hello, this is the built of my second Tlt based "scale " crawler , semi-scale if you consider the frame isn't.

I used a 5poles 400 type motor with an epicycloïdal reduction of 1by100, mounted on a hotbodies rs4nitro center bulkhead and two rear shock tower from a lightning rr, some parts of the tlt kit and i made the other parts from aluminium found at the warehouse:

i have lees flex with the body and it touch the tire so i mount the body higher when rolling.also i must work on the chassis twist when there is nomore traction, and change the ratio of the final gear because it's tooooo slow but with this motor i can run more than one hour with a 800mAh battery having about three times the torque of a stock tlt

i'll post two clips of it in the backyard in the video section very soon....

let me know what you think about it ;) and sorry if my english isn't perfect.

Sweet!!!!!!

RANOVRU · 05-08-2006, 08:12 AM

I like everthing but the stance. Either raise the front up some or lower the rear some and it'll look 10x better.

Nice job on being creative though!

STEEL_CITY_CRAWLER · 05-08-2006, 09:22 AM

very cool, that seems to be an interesting way to go when building 2.2 trucks, using the 1/8th scale rear shock tower approach. and good thinking about the driveline, too. what's the wheelbase on that?? if you want to compete with that, just remember it can't be any longer than 12.5"...

also, i would like to offer the suggestion of ditching the servo saver, and just running a heavy duty servo horn, instead. because at the low speeds travelled by crawlers, the servo saver is not really a factor, in fact, it's a bit of a drawback. mainly because when the servo turns, it is going to turn the servo savers spring, BEFORE it turns the wheels, where as when running a heavvy duty servo horn, you get direct and instant wheel action...

just a suggestion, though...

SammyXp · 05-08-2006, 10:05 AM

Very cool! I am definitely digging the Shock Tower Chassis trend here!

SilverRidge · 05-08-2006, 10:06 AM

Thx, the wheelbase is 32cm about 12.20" but there is no comps for crawlers here in France maybe a national meeting this summer.

and for price of the parts I spend:
shock towers: 2*11€
center diff mount: 50€..outch
home made parts : about 10€
polycarbonate plate: 0

so about 100us$ for the chassis and links

I'd liked to make a double 3links setup but there was no more room between the the center diff output and the motor in the front, maybe making a A arm ...

I have seen that the servo saver is not always a good thing but I have already broken two servos on my clod so I'll do without until I have metal gear ones

dezfan · 05-08-2006, 10:32 AM

A very creative and different approach! Congrats on the build! I love seeing crawlers from around the world!

Great use of parts there, and very sweet ride.

jderreks · 05-09-2006, 05:33 AM

That looks great, quite creative. I like the position of the motor so that it provides some weight leverage for the front.

microgoat · 05-09-2006, 06:27 AM

Very creative build. I like the small chassis. Do you have trouble keeping the driveshafts in? I've never been able to keep dogbones in place; if you've beaten that obstacle, I'd love to hear how.

You might want to put some limiters in those shocks to tame the articulation. 90 degrees is a bit much

Take it down to 60-70 and you'll find it drives a lot more stable.

What's the total weight with the 400 and small battery?

SilverRidge · 05-09-2006, 10:21 AM

The total weight ready to run is 1960gr. with a 1/18th 1100 battery pack but I mostly use a 800mah 9.6 pack 20gr heavier. at 7.2v it's really too slow with this reduction gear.

and I agree with your proposition, put some tube on the shock is surely the most simple way to limit articulation , now the body is the limiter and ...sometime it hangs on.

I' ve noticed no problem with the dogbones on this one, the shaft can fall far lower than the shocks can go down in the front and in rear the parallelogram design avoid it, but on my other tlt( stock chassis with longer links) some time it falls... I think that the point where the links are attached to the chassis must be in line with the dogbone ball , the second solution is to make two different pivot points for lower and higher links so the axle input stay parallel to the center diff output and the distance variations are minimised but it's not efficient for a 4links.

Nice truck man, real nice.

How pathetic is it that people from other countries speak better english than people living in the US?(not a rip on you btw)

nice job btw

Very cool build with nitro parts.

WOODS · 08-31-2007, 03:38 AM

nice pics truck looks good

setecastronomy · 08-31-2007, 06:43 AM

The idea is original, probably it was funny to build it and you can enjoy driving it, but that tranny is definitely not good for competitions.
People debate if Stampede tranny is better than the Stealth or the Losi ones, I believe nothing can be more compact and so low in center of gravity as the R2. During these days I was 'dreaming' an original tranny made with other trucks ' parts but I realized that it couldn't be compared with the R2, so I abandoned the project.

Looks like it turned out good. Kind of different body as well.
