I built this TLT for my son(got tired of him driving mine all the time).Took some cutting and thinking to get everything to fit but I think it turned out great.My son loves it! Performes really well.

specs:
cut tlt chassis
center skid made out of a cutting board (Target $1.89),cut to 2 3/4' X
2 3/4".1/2" x 3/4" cut out of each corner to clear the link mounts and edges rounded so it doesn't get hung up
55t lathe 12t pinion
pede tranny,locked 87t spur
TLT axles,locked
Stampede sliders(traxxas #1951-2 bags)
Traxxas rod ends(#1942)
Traxxas output yokes(#552
Links made with 6/32 treaded rod and 3/16 aluminum tubing
maxx shocks w/ losi yellow springs(losa514 with 15wt oil and 3-hole pistons,left rear has 25wt and 2-hole.
single narrowed front pede wheels with 3.75 oz of stick on lead weight on each rim.Reducer washers as rock rings.2 1/2" fender washers glued to
the inside of the rim for a little extra weight
TLT wideners from the Crawler Store
Tq2 ,Novak XRS esc and Towerpro MG995 servo.
HPI MX-1 body
10 3/4" wide

Looks good. Nice use of the stock chassis. I'd shorten the top links a little.

Why did you lock out the rear like this?


Just courios .

actually the angle isn't as bad as the pic.Camera angle makes it look worse for some reason.The drive shaft angle at the axle yoke is the same at full droop and at full compression,just opposite.

I couldn't mount the short link to the servo plate so I just mounted it to the axle.I'll probably make another for the other side if I can get it away from my son for a few minutes.

Keep the rear axle like it is, you get more clearance before things hit the driveshaft and yoke. The front axle should sit close to zero caster, or even laid back a little for the best steering.

Good job!

looks really nice 72blazer and i may be at the next comp when we have one i hope

Thanks! I shortened the front top links a little.Seems to work a little better.

Crawlsalotlooks really good, what did you use to cut the chassis?

jig saw with a metal blade.Used a dremel with a sanding drum and a file to clean it up.

Rich,hope you make it to the next one,whenever that will be.

Great job.Where did you buy the cutting board and do they have a thicker one other than the one you've used for your center skid?

[rocpede]

the cutting board u can get from wal-mart or a grocery store, and they are about 1/4" to 5/16" thick i think.

72Blazer, the rig looks great! You have given me plenty to think about, thanks.

Hey Rob Do You Run Wheel Wieghts In Your Crawler And The Washer On The Inside Of The Rim Does It Go On The Bead Or
The Back Of The Center

Shaun,I have 3 3/4oz wrapped on the rim and the washer glued to the rim bead.Its exactly the same diameter as the rim.

Hows the steering with the axle tipped down like that. That negative caster would be really bad in a 1:1, but there's no speed here. Does it increase servo load?

Nice build!

THanks! I checked it against my other TLT thats not angled like this and the turn radius is the same.Since the pic was taken I shortened up the front,upper links a bit.Seems to work a little better now.And I never noticed any extra servo load.I'm also running a Towerpro MG995 servo which has a lot of torque to turn the Moabs.

Looking good mate, just wating on a tranny my self, how did you attach tha tranny to the white board?.

I'm using Stampede shafts,Traxxas# 1951,need 2 bags.Had to lengthen them just a bit to fit.

Like Rich said,I mounted the tranny using the 4 screws on the bottom,not the holes for the hinge pins.I actually cut off the hinge pin mounts.I drilled and countersunk the holes in the cutting board and used 4x14mm flat head screws to mount it to the tranny.Or you could drill out the holes in the tranny itself and then bolt it to the skid.There really isn't too much room to mount the tranny AND have a place to mount the links AND be able to mount the skid to the chassie so make sure you really think it thru before you start drilling.
