yeh, a stock tamiya runs a 27t motor and a crap ESC. Well, the stock STK esc isnt anything to ride home about either, but youd think tamiya would have updated their kit ESC's by now. Their esc's dont even have BEC. There is an extra wire coming out of the ESC that has to be plugged into the batt port of your reciever in order to power it. Its very old tech.
I have the stock 1800, a 2000 and a 3000mah nimh packs to run at the track tomorrow. And if I can find my temp gun Ill try a 2s lipo pack. A 2s will push the ESC but Ill only know if it can take it if I try it!
Worst case, I drop in a Tazer 15t esc I got off ebay for $23. That will handle 2s and the stock motor (or even a faster one) without issue.
With the increase in cheap brushless systems, some decent brushed ESC's can be had for very little. The tazer 15t, losi 12t and traxxas xl-5 can all be bought for $25-$35 (used) on ebay. All can handle down to a 15t 540 motor as well as a 2s lipo pack. And on a race track brushed power is plenty fast!
I prepped the body by adding gorilla tape to the inside. I also put in a popcile stick under the hood to keep it flatter. The body was a bit smooshed and that was what caused the fenders to touch the wheels a tad. Gorilla tape is very sticky and super strong. It will not only help prevent cracks, but should one form it will keep it from getting bigger.
Tape around the body mount holes and in the fenders will keep the body pins and wheels from rubbing away the paint.
Now the wheel wells look much better.
