Carbon chssis wont handle driving about on roads etc. Plastic tub wont crack break or chip (TT01, TB03, TF5, TC4)
OK, dont get a TT01 for high power brushless, it is entry level & has some
major design limitations, least of which is the motor mount system & very limited gearing range (Ive had one by the way).
Start buying hops for a TT01 & you will spend alot more than if you bought a TB03 etc etc. Some guys spend over $500 on their TT01, only to find its still only a $100 car.
TT01 is just a basher, DONT WASTE MONEY BUYING HOP-UPS on it
TT01 is VERY VERY low spec
, even some of the generic chinese cars are better specced.
Get a Tamiya TB03R instead. Its like a modern TT01. Race capable(for stock racing), will cope with a 9T brushless IF you get the metal diff outdrives. I had one for a basher with a 9T BL motor.
It shaft drive, 2 ball diffs, fully enclosed gears,TRF shocks,metal centreshaft, CV,s instead of plastic dogbones, same suspension as TA05.
The OFNA linked previously would make a great basher as well i'd expect, with out of the box performance 10 years ahead of the TT01.
