TL01 trail rig

[dyahipfakta]

Need some advice gents. The weight of the cab and any rear section I add will really take its toll on the gearing even with a 70t motor. Gearbox reduction unit is out of the question because I want to keep narrow track so. I really need a smaller pinion anyone done this on a tl01 ?

Haven't tried a smaller pinion, but have had success with really high-turn motors (80t minimum, up to 100t in some cases). Power tool suppliers can usually supply very high-turn drill and lathe motors in 540-size cans, and they are often cheaper than those sold for the hobby industry. Worth a try perhaps?

Andy do you have any room at all for a reduction box ? rc4wd do one that only adds 18mm to the length of a standard 540 .

I had to add 2 mm spacers on the rear wheels to get it to fit as is lol. Such is my dilemma. I have read about it but not actually got any information on how to fit a smaller pinion.

Fitting a smaller pinion isn' that hard, but does require a bit of chassis butchery. I haven't tried it myself, but this is how it was explained to me:

Start by sliding the pinion of your choice onto the shaft of a rebuildable motor, but only tighten it slightly, so that you can still slide it off the shaft with a gentle tug. Then mount the motor to the chassis with a single bolt, and adjust its position so that the mesh is correct. Tighten the motor mount bolt, and disassemble the motor without removing it from the chassis. (This is why you left the pinion loose earlier.) You will now be able to accurately mark the position of the second motor mounting hole, using the can as a guide. Once you have done so, remove the motor and drill the new motor mounting bolt hole using a drill press if possible to ensure accuracy. Reassemble and bolt up your motor using the new hole, and you are good to go!

I've read that it can also involve removing a chunk of the plastic material to allow the motor to "swivel" into place around the fixed screw. I've not done it either but its something I intend to try in the future.

Sounds reasonable enough although my modification skills are some what simpler lol. May have to keep an eye out for a donor chassis for practice purposes.

In the mean time I have downsized on the wheels and it runs much better. What size shocks do you guys recommend for abit of extra height?

I'm surprised you're having trouble with heat, especially with that motor. I'm running a TL01B with a brushless 3500kv motor, a Pro-Line tuber cage and short course wheels/tires, and once I fit the heat sink intended for the DT02, the motor gets warm to the touch, but that's about it. It's certainly not a light car. You might want to look at the DT02 Tamiya hopup heat sink.
