I really want to get rid of the heat sink and Old school brushed motor with speed control and drop in a brushless motor and ESC. so my real question is that if I were to order parts for the ta03 will it fit or are there certain key things that I should look for when ordering parts for this model. I would hate to order parts that wont fit or are wrong. Im just getting back into rc after a very long hiatus
ahh ok... front motor = you've got the TA03F
std wheelbase is ~259mm (axle to axle) and if its a lot shorter than that
then you've got the TA03FS like pictured immediately above
Before you do anything, check that your car has full Ball Bearings.
Every moving part in the transmission has to be supported by BBs,
it needs various # of size 1150, 1510, 1260, 850 & 730.
It would be best to buy a BB kit suited for TA03... F or R doesn't matter.
TA03 has beefy drivetrain which survives any "reasonable" brushless fine.
EZRUN 13T like above is barely more powerful than a Sporttuned brushed;
you could even go EZRUN 9T... note EZRUN are smaller than std motors.
With a std-size motor maybe don't go lower than say 8.5-10.5T.
Best change the pinion to a steel aftermarket unit,
stock tamiya aluminium is too soft & wears out fast.
Once worn it'll damage the other gear too.
With TA03 parts, all parts (except for the F or R-specific bits obviously)
will fit all cars but there's not many hopups that make worthwhile difference.
Std CVA plastic oil shocks work well when built right,
Tamiya TRF alloy shocks are the ultimate if you want an upgrade.
Universal driveshaft is worthwhile, these are same as TA02 front.
Best 03F hopup is probably the "koala nose" bumper shown above.
This takes some of the impact, if the 'blade' on the motor case takes
the full brunt then the motor can shift forwards & ruin gearmesh.
