Robbobs bored and building a shafty
 

Well seeing that my Dominator chassis XR is working so well for me and practice seems to be 2 packs a week I figured I might as well start a sporty build. Not much for being 'ordinary' and remembering how much luck I had with my LCC once I got the right setup and learned how to drive I decided lets do it this way.

So having a girlfriend who understands a man playing with toys is acceptable she tells me about a hobby shop closing up. Ya hey lets go see if they got anything good. So I ask the guy, how much for the Nightcrawler in the corner. He says Ill give it to you for my cost. Hmmm knowing more then he realizes I say well how much did you pay? He says 238$ and its yours ..... So I think thats about 138$ more then its worth but I can use the RTR electronics in the Grasshopper 2 I was getting my daughter so SOLD!

On the way home I got ideas just crushing my tiny cranium and cant wait to get on the CAD and start taking measurements.

Out of the box it comes ....... Girlfriend says 'you gonna drive it?' ....... Nope Im taking it apart to build it my way. She just looks at me and says good luck lol.

Still love these tires ......

And a little RTR shot

So seeing that sporty rigs these days are apparently capable of running pro course the first thing I tackled was the front end. STEERING! Stock just wasnt gonna cut it for me. Seeing rigs with the old TAG kits on them I went hunting. Apparently they are as extinct as the truck itself almost is but I did run across the next best idea.

i found Youngbloods (http://www.rccrawler.com/forum/team-...sportster.html) outrunner sportster build and knew what to do. AR nubs and some fabrication. The part that really drives me about this hobby, make your own parts. Why make them when you can just buy them like everyone else? Well as someone once said ...... 'because we can' ........ and thats what started it.

So stock axle and XR donor

Stock axle and AR axle taped where you have to cut it

Cut - Drilled - Losi ears sanded off - Nice and snug

Now for the axles ...... with my copy from Egressor's XR build. So I take some brass pieces and axles from the oldschool clodbuster. Mix that with a drilled out stock and HD locker and boom I got something going.

So then I take the clod axles and dill them out ..... slid a set of XR fronts in and get them welded

BOOM ...... front axle complete and I got steering

Re: Robbobs bored and building a shafty
 

Now lets do this transmission and narrow it up some ...... So I rolled the stock idler up some which lets me bring the motor in closer to the drive gear. While Im at it lets make a real brace for that idler so 'maybe' we wont blow it out.

And well thats about all I got so far ........ Skid material coming next week puts me at a stall for now but whos in a rush really.

Slow but gonna be fun to build up this dinosaur "thumbsup"

Re: Robbobs bored and building a shafty
 

Hellava start, I knew you'd build a sporty soon!"thumbsup"

Re: Robbobs bored and building a shafty
 

Very nice sir !! "thumbsup"

As a die hard Losi fan,-I most certainly will follow this build closely 8)

Very clean and clever front axle!

And really love that compact transmission ! (hint-hint) ;-);-) "thumbsup"

Re: Robbobs bored and building a shafty
 

Really nice work, How will you keep the brass inserts from spinning inside the worm gear ?

Re: Robbobs bored and building a shafty
 

Loctite 609 and a really really tight press fit. ;-)

Re: Robbobs bored and building a shafty
 

Nice job on the XR10 mod!!! Are we going to have a new source for some Losi parts?

Re: Robbobs bored and building a shafty
 

Do you even weld braaah ? You should stick to cutting carbon parts for me and send me stuff you need welded ;)

Re: Robbobs bored and building a shafty
 

Oh I'm sorry that when I quote from my phone it doesn't give me the option to select specific parts to quote to keep the size down so you're more "satisfied with the size"

Re: Robbobs bored and building a shafty
 

I *think* you should start with the HD worms instead of stock

Re: Robbobs bored and building a shafty
 

Don't know yet ..... maybe but right now its kind of a one build run. The Losi was/is a great truck but I think parts are less found then the XR.

Maybe some small run things to go with other stuff already out but probably nothing big.


That would be a NOPE ...... Braze yes but welding was never a good point for me. I had my ex-father inlaw do this for me. Nice simple flux core "thumbsup".
Sexy doesn't get hidden inside axles ..... 'looks good to me' does :lmao:


Its ok ..... we still love your tapatalk. :mrgreen:


Hows PA been? Ready to come back yet? :ror:



iMAC ? ................ and I thought so much more :evil: :mrgreen:


Yup doing just that. Did the stock one first to see how it was drilling out the locker and fit everything. Now I got a spare stocker and spare HD if something should happen.

Re: Robbobs bored and building a shafty
 

Are the HD spools faster or slower..and where do you get em

Re: Robbobs bored and building a shafty
 

HD's are faster,- 21t vs stock 25t ;-)

Losi part # is LOSA3187,-can be found on Ebay for example "thumbsup"

Re: Robbobs bored and building a shafty
 

And I thought I scored big when my LHS had one set hanging on the wall. Of course he was surprised I knew what they were through all the dust that was on them. :lmao:

Re: Robbobs bored and building a shafty
 

Will the stock worm pinion work with the hd spool?

Re: Robbobs bored and building a shafty
 

No, it won't.

Re: Robbobs bored and building a shafty
 

They come as a set - you actually get two in the package. One for each axle. We generally only use one in the front to spin them faster giving a sort of dig effect/better turning.

Re: Robbobs bored and building a shafty
 

Nope, the pitch is different

Re: Robbobs bored and building a shafty
 

Hey RooBoob, what's that grease feel like?

Re: Robbobs bored and building a shafty
 

I've found this grease very similar to Mobil XHP222 . I have ran this grease in all the rigs thruoghout the years - AX, Losi, Berg, Bully2

Re: Robbobs bored and building a shafty
 

Nasty shet .... Funny story first and recommendation. CUT THE TOP BEFORE SQUEEZING! I took the cap off and squeezed for an instant memory. The bottom sides blow out spewing grease everywhere.

So after remembering that .... I would have to say very close to the Mobil stuff like Heido said, maybe a little thicker. Remember trying some of this stuff before with all the heat/grease talks.

Re: Robbobs bored and building a shafty
 

Been there..... !! :lmao::mrgreen:

Re: Robbobs bored and building a shafty
 

Ok so everything is hinging on how my skid idea turns out ....... think im on the right path so far.

In between some orders and inventory runs I managed to get a skid cut and pocket milled. Its actually smooooth to the feel even seeing the tool marks. Flat tip 2 flute end mill with a .02 step over ... cosmetically I think a .05 step over will get rid of the lines better but good for mine and trials.

And some CF (of course) but for what?

http://i208.photobucket.com/albums/b...ps5bc4hxcb.jpg

The idea is to pinch the lower link pins inplace and not have to use the Losi pieces or change the triangulation from Losi.

And how do we hold the tranny in place? With some delrin mounts of course.

Re: Robbobs bored and building a shafty
 

Dayum Bobbor!!! That's some Krazy sexiness right there!

That CF really pops w/that red labeled HH Crawlmaster Pro in there... ;) mmmmm mmmmm

Re: Robbobs bored and building a shafty
 

Awesome !! Very nice parts !! "thumbsup""thumbsup"

Re: Robbobs bored and building a shafty
 

Got a little work done on the fun box and some stuff done to the Losi ......

Little shot showing the lower links inplace
http://i208.photobucket.com/albums/b...psari1sbkb.jpg

And some of the chassis setup ..... Ill be honest I dont liek the front shock angle so thats gonna be worked on before I commit to any CF material. The rear shocks are on a similar Losi style adjustment. Two screws hold each arm and allow you to rotate them up or down about .125 to alter belly and shock angles.

Thats about it for now but I do have my front axle plate made and was wondering about interest in it. I can say it probably wont fit well between a stock axle but works with the Youngblood or Teng mod.

If theres enough interest I could see us bringing these to production ..... whats everyones opinion?

Re: Robbobs bored and building a shafty
 

Brilliant...I would buy one.

Re: Robbobs bored and building a shafty
 

Ok, so I let me crawl out of my hole and ask a couple questions, as I am not in the now on losi goodies


Do the worm drive trucks handle an over driven front as awell as a R&P truck does?

I seem to see people welding shafts together more often these days. Does it seem to hold? I am a fabricator for a living now, and can tig some shafts together.

Why did you chose clod inners? Cool factor?

Will you cut me those trans parts?



I recently got an itch to fart around with a losi, and was thinking of offering XR conversion junk. But Im not sure how popular they would be, or if anyone even does losi stuff these days

Re: Robbobs bored and building a shafty
 

I drove my old LCC for a long time with the HD gears in the front. I cant say I ever felt it wasn't enough but that was also in a pro class with digs. Never felt any bind or like one axle was dragging or pushing another.

I chose the clod pieces for two reasons. I felt that if I can get all that steering into the truck then it would help the axles telescope a little and take some stress off the joints.

Also using the splines I had more of a hold on the axles in the locker and less of a chance of rounding off the stock square ends over time. Who knows though I could wind up spinning an insert with the luck I have at times.

Also it was easier for me to drill the clod stub out and slide the Xr axle in then to try and butt the two pieces together to weld them.

PM me on the tranny parts .....

Re: Robbobs bored and building a shafty
 

I'd buy some xr conversion parts :)

Re: Robbobs bored and building a shafty
 

Ok so not much of a build thread compared to some of my past ones, just dont seem to have the minutes left in a day to update everything. My fault but I do have a runner.

So after some talks with Jens on the front axle plate I made some changes to it. Noticing I couldnt get all my steering and the battery was stuffed in the wheel I brought the servo and battery in a bit more.

So we went from this .... notice the top screws and servo location ....
http://i208.photobucket.com/albums/b...psugcirhnd.jpg

To this and counter sunk screws
http://i208.photobucket.com/albums/b...psj0u5qyqu.jpg

There is a v3 coming though that moves the servo back and over to center a bit more plus the battery over as well. This should clear me up for max throw.


So heres my infamous paint job that brought me luck with my old pro rig .... and some shots of the under carriage.

More to come later on ...... got some skinny things coming in for a change. Got a couple packs of practice and was pretty impressed with its first outing. Some more test n tune for her and Im sure shes gonna be a front runner with a real driver behind her :mrgreen:.

Re: Robbobs bored and building a shafty
 

how long did your axles end up after you welded them. i am scheming my next build and i really like the direction you went with on the axle. great looking build , i hope to have a sporty built by spring.

Re: Robbobs bored and building a shafty
 

Boy you like running those unpainted bodies. I had one that looked just like it.:roll: it just got painted last week.

Re: Robbobs bored and building a shafty
 

Wow.....

Alot of Cool stuff in this thread..........."thumbsup""thumbsup"


Very nice........






Oh....
i know someone who has a nice purple & pink xciter body in the vender section,
he might be willing to trade.......:ror::ror:

Re: Robbobs bored and building a shafty
 

I still have to fix the axle weld I broke on the first course of its first comp ......... :shock::roll::ror:

That was 3 months ago lmao .....


I love the clear bodies though - I get distracted easily :ror:
