OS's CFX Killer
 

Been having a lot of fun wheeling around my little CFX. I've had all kinds of ideas on modding it for better performance, but I kinda like it as it is too - the challenge is part of the fun.... so what to do?

Let's build a new truck! (any excuse to mess with random parts really...) Similar dimensions and still using a CC size body but with the performance mods I wanted to incorporate into the CFX. Sure, let's go with that.

I used this truck as the base and started mocking up a lower driveline that incorporated OD...with such a short WB, I think OD will help tremendously. Started messing around until I had a layout I liked. Proof of concept...kinda. Compared to the CFX in the background, it's much lower COG-wise.

The chassis could have worked, but I wanted to incorporate some changes, and the old one was getting holier than the pope after being modded so many times so I cut up a new one. Really, it was just an excuse to cut up some metal.... incorporated the shock mounts and straightened out the back.

The tried and true HPI reduction...used a piece of ABS to span the chassis and mount it. Seems solid, though delrin would have been better - I might come back and make an aluminum mount later that's a bit stronger.

Mounted up a Hammer t-case set up for OD. Little more OD than I would prefer, but should be ok with the kinda tiny tires. My trans ratio is only 10.89/7.41 front/rear with this setup though - definitely need more reduction somewhere. I kinda have a plan....

Axles are my last pair of TLT's with all the goodies from back in the day... MIP's, clocked C's, HD lockers, etc. I was debating a set of MST axles since they have better steering, and are the perfect size, but the TLT's were doing nothing but gather dust and the MPA axles were $100. So TLT's it is!
https://farm1.staticflickr.com/949/4...66018400_b.jpg
https://farm1.staticflickr.com/965/4...d63cb5ac_z.jpg

Front axle mounted up...it's tight, but it all shoehorns in there. Went with a 3 link w/panhard so I could drop the motor as low as possible.
https://farm1.staticflickr.com/981/2...03cd5fb9_b.jpg
https://farm1.staticflickr.com/964/4...abfe6db2_b.jpg

On the rear axle, I swapped the truss for a Dinky link I found in my stash for more clearance.
https://farm1.staticflickr.com/980/2...a03e264c_b.jpg

Tight back here too, but it all works. I was worried about the driveshaft angle, but it seems ok.
https://farm1.staticflickr.com/954/2...3d2bfe69_b.jpg

Ordered a few parts, so I'm kinda stuck at the moment.

While I was waiting for them to come in, I started messing with other stuff. These old Outcroppers are going back on - they are not comp level tires to be sure, but there's just not a lot of great tires at or under under 100mm, and these seem to work pretty decent - inline with my driving abilities anyway, so using them for now...I did open them up with a dremel a bit which should help. Modded tire on the left

Pretty much it until the UPS guy gets here. "thumbsup"

Re: OS's CFX Killer
 

watching this one like a hawk! stoked to see another tlt build!"thumbsup"

Re: OS's CFX Killer
 

Parts came in yesterday....if I can tear myself away from 'Dega today, might get some work done. :)

Re: OS's CFX Killer
 

Made a little progress yesterday before the race.

Took off the HPI trans to hook up the gear reduction and found out 2 of the three screw bosses broke off. Very strange, never had that happen before. Broken one on the left... thankfully, I have a spare that I swapped over.
https://farm1.staticflickr.com/976/4...76b9d169_b.jpg

I needed more reduction, so I put a 4:1 RC4WD unit inline with the HPI giving me a total trans ratio of 29.6. Should be in the ballpark, if sill a little tall. Used a Tamiya mini motor to power it all, though have room for a full size can if needed.
https://farm1.staticflickr.com/864/4...635cc196_b.jpg

Mounted up in the chassis. Kind of an odd trans setup, but it's fairly compact for what it is
https://farm1.staticflickr.com/958/4...3c5da3c3_b.jpg

Squeezed a steering servo in...had to bend the panhard and add some offset rod ends, but it all clears just barely. The panhard and steering links look off, but that's just due to the bends. I get full movement with no binding and no bump steer. The MIP's give a whole lot more travel than the stock TLT parts - it's right at the same angle as the CFX at full lock.
https://farm1.staticflickr.com/869/4...331e56c7_b.jpg
https://farm1.staticflickr.com/826/4...ef90c320_b.jpg

Wheels and tires back on - got a roller! The 8-holes were already drilled out to fit over the MIP's, so left them on there. They are weighted inside - weight down low is critical with such a short WB rig, and I don't know of any way to add weight to a TLT axle, so the wheels got some lead. The Outcroppers are a little stiff being an older compound tire, so dremeled a bit on the inside of the tire to thin it out and put a super soft foam in. Feels pretty good on the bench. We'll see.
https://farm1.staticflickr.com/959/4...eb7de872_b.jpg

Need to figure out some sliders, electronics and battery mounts and a bumper of sorts, then tear it down for paint.

Re: OS's CFX Killer
 

I have 6 of those HPI gru's in trucks and another 4-5 on the shelf. i love them.
i have had one out of all them being used break a nub like yours did. all others are fine.
nice to see these older rigs (parts) still get love.
keep it up "thumbsup"

Re: OS's CFX Killer
 

Get a little more work done on this little guy...

Bent up some 2mm aluminum and made some boatsides. Plan to make some steel sliders to cap off the ends.
https://farm2.staticflickr.com/1786/...89d3cb89_b.jpg

Perfect fit under the Tamiya body, and a nice place to mount electronics.
https://farm2.staticflickr.com/1783/...d6bdf02b_b.jpg

Bumpers back on...rear is a modified Sawback front bumper.
https://farm2.staticflickr.com/1807/...efa776a1_b.jpg
https://farm1.staticflickr.com/884/2...1ef669e4_b.jpg

Zip tied in the old battery tray...not quite sure where I want to put it yet
https://farm2.staticflickr.com/1765/...5de6d777_b.jpg

With all the electronics mounted, it's pretty low profile.
https://farm2.staticflickr.com/1770/...738d41dc_b.jpg

Now onto fabbing up some sliders and getting some paint on. Have to tear down the entire chassis and spray it black as well.

Re: OS's CFX Killer
 

Very nice build, i should try and do a rebuild to my last tlt axles i have left which coincidentally i have mounted the fj40 tamiya body from the cr01.

Re: OS's CFX Killer
 

You should! TLT's for life! :)

I've driven this round the shop a bit, and I'm not sure on the overdrive. It's too much imo... drags the rear tires noticeably. I'll get it out for a test run though first before making any changes. Do need to get my paint shop set back up and spray some color first.

Re: OS's CFX Killer
 

(2 months later)

Everyone is out building VST's, and here I sit playing with TLT's still. :)

SO finally got my paint area cleaned up and ready to go. Been a while since I totally pooch-screwed a body, and I was due for sure. Mission accomplished! My airbrush had a heck of a time spraying the white - not sure if the paint was old or what. But I didn't have much left to begin with, so the white got very blotchy. Unfortunately, the black backing layer really bled through....the white looks terrible. Not to mention the sub par masking job that bled here and there. Of well, what's done is done.

Some of the black is overspray, but sadly, not all of it.
https://farm1.staticflickr.com/854/4...39eb843d_b.jpg
https://farm2.staticflickr.com/1780/...691746cb_b.jpg

Decal time. If you've ever done one of these bodies, you know it's an extreme exercise in patience. Each window is 2-4 tiny, uncut decals that take forever. Hopefully the decals hide some of the paint disaster... hopefully.
https://farm1.staticflickr.com/862/4...36d0e442_b.jpg

Re: OS's CFX Killer
 

That has to sting a little. Looks like it would have been a really unique paint scheme. Can always reshoot on the outside and try to recover?

Re: OS's CFX Killer
 

Building VST's? Did you mean MST there or is a VST something I'm unfamiliar with?

Too bad the paint didn't work out. That's heart breaking. And this would have been a rare non-blue paint job from OSRC! Sad. Hopefully it looks OK with the decals.

Re: OS's CFX Killer
 

VS4-10 T breaker one-niner. Too many letters, I get myself confused. :)

Re: OS's CFX Killer
 

You should run that body over to Jato, you know he loves to paint. :roll:

Re: OS's CFX Killer
 

Ha! Let's not get crazy!

Paint and decals done finally. Holy cow, does this thing take some time to decal up.. Since I'm running TLT's and a Tamiya body, decided on a modern Rough Rider theme. Think it came out OK - would be far better if I didn't screw up the white but I can live with it.

https://farm1.staticflickr.com/852/2...4c6feae0_b.jpg

Drive-wise, it has a very low COG with the motor hung as low as possble so it's pretty stable. Those old Outcroppers are still pretty grippy and make cool whooshing noises when they spin on the rocks.

Using the RC4WD t-case as overdrive gave far, far too much OD to the front wheels. Was literally dragging the rear end up and over stuff. Sometimes that's good, but I had no drive at all in the rear, so the front was doing all the work. That's no good. Motor was super hot after just a few minutes of testing which I hope was due to the axles fighting each other. Going to remove the OD and just set it up as a std. t-case

Too bad there's no "vintage class" of crawlers...feels like I should have a Stampede trans stuffed in here. :) Compared to a newer kit, the steering on this is just laughable. BUT it is fun to wheel regardless. Still needs sliders and think I'll finally break down and paint the chassis.

Re: OS's CFX Killer
 

Man, that came out looking really sharp! That's one for the "is that really an RC?" thread.

The white actually looks good too decaled up...just gives it sort of a dirty/driven appearance. A good modeler, like a good carpenter, relabels "boo-boos" as "character". "thumbsup"

Nice job! Hope your regearing solves your issue.

Re: OS's CFX Killer
 

Man-o-man does these pictures bring back memories..... The TLT started it all for many of the oldschool RCC members including myself.... You might be starting a new trend here my brother....... Great work on the chassis and floorboard/sliders.....

Re: OS's CFX Killer
 

Amazing what a bit of time with a Sharpie marker can do to a lexan body...

Speaking of vintage, I've got a few sets of WK axles, Proline 2.2 mashers, a bunch of stampede transmissions, and a few old style chassis laying around. Hmm.... Vintage crawler build? Got the wheels turning for sure.

In the meantime, tore this truck down and sprayed some paint yesterday between storms - pics to follow. Apparently all the rain that should be falling out west is bombing the east coast. This is getting crazy. My pool overflowed last night for the first time ever.

Re: OS's CFX Killer
 

Been chipping away at this thing over the past 2 days. First thing I did was get rid of the overdrive. Flipped the t-case, swapped the input to the other side, drilled 2 more holes and it's good to go. Piece of cake! Before and after:
https://farm2.staticflickr.com/1815/...da29468c_b.jpg
https://farm2.staticflickr.com/1791/...e5b808f6_b.jpg

The ABS mount I made might have been strong enough, but there's a whole lot of weight hanging off of it, and I feel better with something more solid. Found some old server rack mounts I brought home from work that were made of 6mm aluminum. Two hours of sawing, filing, and drilling later, I had an aluminum mount instead. The sliders on the boatsides are made of brass. I had a slight mishap with the brazing involving flying magnet shrapnel and took the easy route.
https://farm2.staticflickr.com/1833/...b8df23ef_b.jpg

Stripped the chassis down and sprayed everything flat black.
https://farm1.staticflickr.com/940/4...0f06076f_b.jpg

Feeling better about the motor/trans mount...much more solid.
https://farm2.staticflickr.com/1814/...20ec4664_b.jpg

Axles back on and almost a roller
https://farm2.staticflickr.com/1780/...398901ba_b.jpg

Wheels and electrics. Good to go!
https://farm2.staticflickr.com/1794/...1cbd4c94_b.jpg

View of the front. The shocks were hydro-locking with too much fluid, and really, really inconsistent with a bit too little. Not a fan of these at all, I cannot get them to operate smoothly for the life of me. Drained out the oil for now so they at least cycle smoothly. It'll be a bouncy test ride for sure. I'll dig into them later to see what I can do.

Side view.
https://farm2.staticflickr.com/1814/...04a875ca_b.jpg

Front axle setup. Great caster and pinion angle from the clocked's c's - they make a huge difference on the TLT axle imo. Motor is as low as possible up front given the short wheelbase.
https://farm1.staticflickr.com/935/2...b6af28dd_b.jpg

Re: OS's CFX Killer
 

Body back on and ready to go. Swapped the wheels for a set of old white ones I've had in my box-o-parts since ... well, forever. I have no idea how old these things are, but finally found a truck they look decent on.
https://farm1.staticflickr.com/858/4...4cd74fe5_b.jpg

This body looks great with 1.55's, but all the ones I've tried are just too much offset with the TLT axles. I need a wheel that will narrow the track width as much as possible, so I've been sticking with the 1.9's. Think I've got a good amount of tire coverage with this combo.
https://farm1.staticflickr.com/854/4...1b0c51c0_b.jpghttps://farm1.staticflickr.com/935/2...38a5583b_b.jpg

Gotta have a flex shot or two. About the same as the CFX/CMX.
https://farm1.staticflickr.com/939/4...57610fde_b.jpghttps://farm2.staticflickr.com/1832/...d358e90e_b.jpg


Comes in at 5.6lbs and a 53/74 front weight bias. Right where my CFX is - should be an interesting comparison! My only concern is that mini-motor up front. It was way hot on the first test run, so I'll be keeping an eye on it. It's geared way down though, and the motors do fine in my CC chassis, so we'll see how it does here. I've got a regular can 35t on standby.

Re: OS's CFX Killer
 

:shock:, super nice job on them tlt's, the body looks really good to, anxious to see your final test results i will definetly take some notes from your build for mine.8)8)

Re: OS's CFX Killer
 

I'm building a "test course" so I can compare Apple's to Apple's. Fun project... hoping i can dial rigs in right in the backyard so i dont have to load up everything and drive out to my local crawl site all the time.

Re: OS's CFX Killer
 

That looks great! Love the double GRU type transmissions, white wheels go well too! As you said fun to drive!


I haven't done the Hammer tcase OD mod on my TF2 because I was thinking it would be too much OD and the way it works, I'd need to gear down more. I'm already at 11T pinion and spur has no room to go bigger. Great job! "thumbsup"

Re: OS's CFX Killer
 

Thank you good sir!

I know the OD mod is very popular - maybe it works better with a longer WB? I haven't given up on it, but I think I'll have to make my own for it to work.

Re: OS's CFX Killer
 

Finally got my CFX sorted out the way I want it, so as soon as the weather cooperates, it's time for a comparison! Is the "CFX Killer" going to live up to it's name?

First, some comparison shots and info. Forgive the crappy pics, my cell phone (Samsung J7) has a straight up terrible camera! And it apparently doesn't like humidity since it wouldn't focus worth a damn.

I painted up my CFX with the same body and WB, though it's running 1.55's ilo 1.9's.
https://farm2.staticflickr.com/1891/...88f930a8_b.jpg

The CK has a wider track, and sits a bit higher. The stance didn't look right with the wider axles sitting low, so it's a bit jacked up.
https://farm2.staticflickr.com/1884/...f122c612_b.jpg

Overall ground clearance is about the same though.
https://farm2.staticflickr.com/1864/...51860164_b.jpg

Flex-wise, the CFX wins. Though the CK has 80mm shocks, the 70mm shocks on the MST have a bit more actual travel. Not to mention, they are much smoother. The CK still needs some shock work for sure.
https://farm2.staticflickr.com/1819/...6bf3f28b_b.jpg

Chassis shots of each. The CK has the motor much, much lower in the chassis, though the battery sits a bit higher. With the wider axles, it's COG is much lower overall.
https://farm2.staticflickr.com/1873/...1a5a5111_b.jpghttps://farm2.staticflickr.com/1838/...d85de058_b.jpg

I'll be throwing my CMX into the mix too. Why not? :) Maybe even a CC01 since they all use the same size body. Tiny tire trucks are taking over here in my shop lately. As they stand right now:

https://farm2.staticflickr.com/1852/...4d59943e_b.jpg
CFX Killer: 2564g, 49.3% on the front axle. Tamiya X-Axto motor, Xcar 45a ESC, Tactic TSX45 servo
CFX: 2406g, 55.3% on the front axle. 35t motor, WP1080 ESC, Tactic TSX45 servo
CMX: 2389g, 53.5% on the front axle. 35t motor, Xcar 45a ESC, 645MG servo.

THe CK has a rear weight bias - that's no good. I'll be giving it a test run first and I'm pretty sure that the Tamiya mini motor will get swapped out to a standard size 35t - that should bring it at least even balance-wise.

Ready to play - if the rain ever stops!

Re: OS's CFX Killer
 

Great comparison, I agree test it first and get it dialed in better, fullsize 540 motor would help bias and power. Maybe move the lipo cross the frame rails just ahead of the ESC and transfer case. :)

Re: OS's CFX Killer
 

Way ahead of you Natedog! :) Got a bit done over the past few days.

First thing to tackle was the shocks. They were completely hydrolocking with oil, and sticky to boot. Pulled them apart and found the holes in the pistons were blocked by the e-clips. Yup, that'll do it. Used the dremel to semi-scientifically notch the pistons so oil can flow no matter where the e-clip is. Also swapped out the old, swollen O-rings with some Tamiya red rings. Not great, but they actually function now.
https://farm2.staticflickr.com/1847/...c3488833_b.jpg

Battery moved up to sit on top of the t-case longitudinally. With the motor swap, brings me to a 55/45 weight balance - much better.
https://farm2.staticflickr.com/1883/...9f87c0af_b.jpg
https://farm2.staticflickr.com/1871/...2e6f6517_b.jpg

Have a bit of clearance issue at full comrpression up front where the driveshaft hits the trans mount. Switched from a WB to a GDS driveshaft as it was a bit thinner. Still hits, but just barely. I'll keep an eye on it.
https://farm2.staticflickr.com/1868/...63a7391c_b.jpg

Swapped in a 35t motor/WP1080 ESC as well. Mini motor probably would have been fine as geared down as it is, but I could use it somewhere else anyway. These Gool/Hackmoto/whatever $10 motors are pretty nice for the price. Especially compared to some other throwaway motors at the price.
https://farm2.staticflickr.com/1873/...9ccd80be_b.jpg

Did some testing. Tires are just awful...I remember them being OK out on a trail run, but on rocks and plywood, they were just terrible. Well, they did make cool whooshing sounds as they slid/spun, I guess that counts for something. I forgot to vent them, might have something to do with it - very bouncy.
https://farm2.staticflickr.com/1900/...3066281a_b.jpg

I figured the gearing for a 1:1 t-case, and later decided on the RC4WD case which has more reduction in it. So the truck absolutely crawls. doesn't even do walking speed. Couldn't get up the 50d ramp - first truck to fail to do it.
https://farm2.staticflickr.com/1858/...0c77dcc3_b.jpg

*Sigh* 1 step forward, 2 back. Back to the workshop for some changes.

Re: OS's CFX Killer
 

Back in the shop to make some changes...

First off, even though the shocks were better, they still sucked. Period. Fronts came out better than the rears for some reason...still sticking a bit, and very stiff. Since the rear were the worst, I started experimenting. I found that Axial shocks limited by 10mm with MST springs from my CFX worked out very well. A bit more travel and far, far smoother. Just had to change out the mounts on the bottom.

Before:
https://farm2.staticflickr.com/1852/...bc427bdd_b.jpg

After:
https://farm2.staticflickr.com/1867/...eb2190a0_b.jpg

All done. I actually have suspension action again! I'm out of shocks ATM, but the front will be getting the same treatment.
https://farm2.staticflickr.com/1899/...93bb2977_b.jpg

Though the double GRU might seem like an odd transmission, it works out very well. 3 screws to remove the trans, 3 screws in the HPI GRU, and 2 in the RC4WD and the entire "transmission" is out and open in less than a minute. Replaced the 4:1 with a 2:1 hoping to get some wheelspeed back. Took all of 5 minutes.
https://farm2.staticflickr.com/1891/...cb3f50df_b.jpg

Back to testing.. Can't emphasise enough how nice it is to have a place to test right outside.
https://farm2.staticflickr.com/1844/...2232e230_b.jpg

Wheelspeed was better, but still a bit slow. Thinking a 1:1 t-case might have to go on. I think it'll be too fast if I remove the RC4WD GRU, but I might try it anyway before coming up with a new t-case setup.

I did swap on some 4.19 Hyraxes and traction was much, much improved. I think they look a bit big, not sure if I'm leaving them on or not.
https://farm2.staticflickr.com/1858/...fbae2ba9_b.jpg

Still failed the ramp. Mostly, made it once just by a fluke. Just doesn't have any wheelspeed.
https://farm2.staticflickr.com/1869/...f89c50c0_b.jpghttps://farm2.staticflickr.com/1870/...9262fc98_b.jpg

So - much better...still some work to do on the driveline and front shocks before calling this one good.

Re: OS's CFX Killer
 

Are the GDS metal driveshafts female half splined all the way through? Agree that the Hyrax look a little too big on there, but I'm sure the performance is 10X better. :)

Re: OS's CFX Killer
 

I'm not sure, but I'll check next time I have it apart.

Re: OS's CFX Killer
 

Finally got the driveline sorted out. I was looking at different GRU's and T-cases to get the FDR right... it was a bit undergeared previously. Great for torque, but wasn't quite at walking pace - not going to work on a trail run.

I ripped the Revolver out of my Wraith a while ago and it was sitting on the bench...low RPM's, gobs of torque...hmmm. Bolted it right to the HPI GRU with no other reduction and it's absolutely perfect. Great torque and just enough wheelspeed to get down the trails. Not to mention the smaller size works out perfect. I'll have to keep this setup in mind for future rigs.

https://farm2.staticflickr.com/1874/...cd53f3b5_b.jpg

And thanks to all the of the room I had availble, finally got the winch wired up. RC4WD controller stuck to the side of the servo.
https://farm2.staticflickr.com/1874/...cd53f3b5_b.jpg

I started adding lights to the truck as well. I'm not big on lights per-se, but so far it's looking decent. Does need an interior or something, the body has a lot of windows and it's mighty airy in there.

Re: OS's CFX Killer
 

Last time I was out wheeling, I made the remark "I'm totally done with lights"

1 week later, I was adding them to my truck. :) I had a Tamiya light kit sitting around, so why not. Though I was more focused on performance with this truck, I went ahead and added a roof rack too. Think it all came together pretty nice.
https://farm2.staticflickr.com/1951/...14d8c6a0_b.jpg
https://farm2.staticflickr.com/1915/...307daa87_b.jpg

Added some lightweight "cargo" up top and tinted the windows out back a bit. It's a sad substitute for an interior, but it'll work for now.
https://farm2.staticflickr.com/1926/...e4360125_b.jpg

Re: OS's CFX Killer
 

Finally got the little TLT truck out out for some proper wheeling. Funny, of the 10 or so guys left after our main trail session, not one of them ever even heard of a TLT. :) After driving the TRX4 for 4 hours, switching to this truck was a rude awakening.. :) Steering is not the best, ground clearance is much lower, and the tires are just awful. Nevertheless, got the feel for it after a while and had a good time crawling around.

NO MOTOR VEHICLES!
https://farm5.staticflickr.com/4870/...3cef50bc_b.jpg

Wet, mossy rocks and 10 year old Outcroppers just don't mix.
https://farm5.staticflickr.com/4822/...37776207_b.jpg
https://farm5.staticflickr.com/4903/...85114eb3_b.jpg

Did get up some pretty serious inclines though...mostly with wheelspeed and some luck.
https://farm5.staticflickr.com/4835/...4578a66b_b.jpg

Very happy with it though. Went fine down the trail, which is what I was hoping for. Even though the tires were not the best, the weight balance and overall handling of the truck were very good. And it came back in 1 piece after 90 minutes of pretty serious trail time. I'd call that a win.

Re: OS's CFX Killer
 

I remember TLT axles, did a build with them once, they worked ok, not my top choice but they worked. That rig is sweet looking though I really like it!

Re: OS's CFX Killer
 

Whatever happened to this cool old school build?

The stacking of reduction boxes is genius, yet the revolver is even better you say? Would you say the revolver will creep as good as a brushed motor running twice the reduction ratio?

I still have a functional tlt axled rig. Built it from mostly spare parts for my kiddo to run. Just wish it turned tighter. Any chance some place still has MIPs for it that you'd know of?

Still have it, it's doing a great job of keep my self from flying up and hitting the ceiling.

Revolver is a good match as this truck has somewhat tall gearing, and was way too fast/low torque with a 35t motor. An outrunner by nature does not rev nearly as high, but produces much more torque so it's a pretty decent match for the tall gearing. Newer Revolvers creep along amazing at low RPM, no special gearing needed.

No, no idea - pretty sure TLT MIP's are long lost unicorns at this point.
