Klampyz HSP MOA 1/8

[trevely15]

nice job brendan!
never seen a scale 1/8 moa.
them wheels and body make it look soo scale!!
im gunna have to think of some scale ideas for my scx like you lol

 

[klampykixx]

thanks tom. ill be sure to keep ya posted.

edit: and in fact, ive got a small update to come on tonight. did some more drilling. man i love my new drill press!!

 

[klampykixx]

ok. so as i said earlier, i got to drilling some holes last night. didnt get to post pics tho. so, after drilling the stub axles the first time i realised they were a tad tight. so that one stub that has the pin in it, wont be coming out... lol however, the remaining three, got slightly oversized so the pins now sit free, but are grub screwed in.

here is the original offset with the pins in the stock location, washer/spaced out.

and now the new offset, which im hoping the new rims will actually sit even closer in over the C hub.

and ive been playing with geometry. wasnt happy with the amount of droop travel the front end had. it now will compress all the way to the bottom of the shock where before it wouldnt due to the way it was before. made it so that a crossmember was the limiter. so, after drilling some new holes in the shock "hoops" i was able to get the top of the shock lower, so now the shock is the limiter of up travel, and the "equal-and-opposite-reaction" is more droop than before as the top is mounted lower than it was. = win win. more up, more down!!

heres how it looked last night...

 

[klampykixx]

so i saw a thread here that showed how to make a winch from a servo.

so i took a normal cheap leftover Venom servo from a touring car i had way back,

free rotation modded it. gutted it. and then drilled the splined output shaft and the back cover to allow a alu shaft a through passage.

then drilled across the splines and put in one of the screws out of another servo and bent it around for a lock pin (interesting to see what sort of loads i can pull with this as its pretty light duty...)

drilled another hole in the shaft and threaded some rope in.

and after winding about 2m on, replace the back and wallah! servo winch!

 

[klampykixx]

look what i got today!!

they just look so much better!

and way better offset as well. only half poking instead of 110% poke...

new:

old:

much betterer.

so ive been playing like a child and rolling my truck around by hand but have come to the conclusion that i didnt like the suspension geometry the way it was. so with my dremel and a new accessories pack, and my new drill press, i decided to make a new mounting bracket for the front LCAs and the upper rear shock mount.

please excuse the crappy welding. my welder sucks. its either full bore or piss weak. tends to either blow holes or just not weld... but, i do what i can with it as its all ive got...

front LCA mount.

rear upper shock mount.

with the rear shock mount, to get mega flex (and i mean mega) i just need longer shocks. but for now, its second from the top, and it feels a good mix of flex, and stiffness.

current ride height and flex> (i didnt take into account the less angle on the LCA pushing the axle forwards... :/ )

but shes pretty flexxy, and i must say, its better now. less droop, but more tuck. i think i prefer this.

 

[klampykixx]

rear hubs sorted out. now just gotta finish the fronts so they look like actual hubs.

just another random flex shot.

then, something ive been thinking about doing. decided to do it. made a template up first to make sure it would look ok.

then drew it up.

and here we are. gonna finish cutting the lower half tomorrow as its 11.15 pm here atm.

 

[klampykixx]

finshed the main part. mounted up. and its bolted on! just waiting to get my EXO light bar to do the rest.

edit: still needs to be cleaned up and painted, but ill wait till im finished welding and drilling etc.

still thinking about mounting the winch inside the bumper.

"still thinking about mounting the winch inside the bumper"... Do it.

You have a very unique rig started, and unless you are in a real hurry to consume plastic gears, I'm betting the most fun (for all here) would be if you display and refine your talents down to the last detail.

Personally, I would appreciate a running weight total, if you could? Just for reference... the bleeding edge types here have gone all anorexic, and I'm convinced it will be good for all of us (to some degree) in the end. I'm not suggesting you follow suit, I'm most interested in drive train stress and learning what kind of power different rigs need.

Good choice on the wheels. Steelies have that no BS look that makes scale work for me.

good as done! ive been assessing how much space is actually in there. and theres plenty below the grille.

thank you when you talk about refining my talents to the last detail, are you referring to the scale factor or driving style?

as of saturday, old bumper, body and rolling chassis, no elecs. it weighed 6.6kg which is getting pretty close to spot on as far as scale weight is concerned. im in no way close to competing with the bodiless chassis'ed super class crawlers, but would certainly love to have a crack! :lmao:

also, to add. i have a pair of turnigy2.2 lipos. theyre 2s and 2200mah 20c. one for each axle basically

Good choice on the wheels. Steelies have that no BS look that makes scale work for me.

thankyou very much. I love these rims! they look so tuff, no nonesense. i still might get the next size up tire. but for the moment, the crushers are growing on me for sure.

 

[ekd]

I was referring to your fab and your problem solving skills.

Those tires are just right IMO. They look like just the size your tire guy would sell you for an offroad work truck... if he was a friend.

I'm trying really hard to avoid (as long as possible) being bit by the scale bug (I hear it's pernicious). You are NOT helping.

ha ha! yes the scale bug bites and doesnt let go without copious amounts of scale therapy. and that only eases the pain by treating the symptoms lol. i must say though, the longer the bug stays the harder it is to get rid of it!

my problem, is i bought a crawler. it broke, and i let the bug win!

thanks for the kind words.

ill be having a crack at a winch mount tonight. i made the bumper have proper mounts so is 100% removable.

 

[klampykixx]

so heres a thread i started on lipo charging: http://www.rccrawler.com/forum/electronics/391792-parallel-singular-lipo-charging.html

that leads to this>>

which goes in here>>

and then looks like this>>

so these can live in here>>

What an awesome build, i had one of those HSP crawlers a few months ago and just made it extra super, never even thought of turning it into a 1/8 scaler! What steering servo are you using for all that weight, and did your HSP come with rear steer equipped?

 

[klampykixx]

hey! thanks for the kind words steering servos are just an ebay 12kg servo, one at each end. not here yet tho. had rear steer, but was setup on lockout. so all i had to do was introduce the servo and hey-presto rear steer. especially easy to do knowing all i had to do was shift front setup to rear and do chassis mounted servo up front.

im almost certain the 12kg wont be enough for the fronts but it will be better than what was there.. 6kg?? i think... and for the fact its not a "crawler" i shouldnt need on-the-spot steering power like a crawler would. just drive forwards a touch and frees up the steering.

anyway. im in the process of sorting out where the elecs are all going, so ill be posting progress as it happens.

 

[klampykixx]

so more electronics been sorted out tonight.. not a fan of the tiny soldering. or wiring the truck for that matter. consider it a PITA!!

anyway. pics!

6v relay and micro servo board ill be using to switch the 14.4v light circuit on and off with.

and my crappy soldering job...

messy or what!?

and a shot of under the tray showing wiring for tails.

 

[klampykixx]

just playin around with the suspension. i love how soft it is with currently no shock oil.

Do you mind if i ask where you bought it? mine came with HSP-branded 9kg servo's which died within a few months, but come to think of it i did do quite a few winter missions. If yours are 12kg then that should be fine, but i found my 9kg's stalling out fairly often. Mine also came with a pre-mixed 3ch radio for crabwalk, rear steer, front steer, or dual steering, as well as rear steer already quippefd and running. I purchased mine from a local dealer here in Ontario, RC Hobbies Outlet Canada. Did yours come with a HSP dual-motor ESC? I had major clod stall problems with that esc, never quite figured out how to solve it.

As for the electronics positioning, I replaced the awkward lower battery tray with the upper electronics tray and put all my electronics there. For such a heavy beast it seemed to work just fine.

I found an couple old pics of mine and a link to an old video in my yard taked by my cousin.

:nice:

i got mine from a friend so not sure where it originally came from. online i think.. currently has the red anodised servo in it and according to ebay, the hsp replacement seems to be around about 6kg. so i found the next cheapest option lol. got two at $8 each. Stall torque: 9kg/cm(4.8V),12kg/cm(6V)

 

[chris78cj7]

I cant believe this is the same truck i just got... Wow really nice work and thinking outside the box with this Hsp. Never would of thought..
