Motor Q's

[da_ticklah]

Greetings all I've got a few questions about the TC3 RTR I just got. The main thing is the car feels slow (my other car is an NTC3)

I know it's got the Associated Power 19 motor in it but is that consistent with other 19 turn motors or is that a pretty crappy one. I have done a lil searching on this board and see that there is a concistent cast of characters for reccomended 19T motors(Assoc Quad Mag, Trinity Chameleon, Team Orion).

Would I be looking at a noticeable jump in speed if I went with one of those or would I be better off trying to squeeze in a 17T Speed Gem in there, I'm trying to hang on to the stock esc for a lil bit.


Side Q
This will probably date my electric knowledge but when did stock motors get adjustable endbell's?
I remember stock being 24deg or less fixed 27T motors


Thanks!

Yes, you will notice a healthy boost in speed by using a competition stock or 19-turn motor. The motor in the TC3 RTR is decent, but it's not nearly as good as competition motors.

Side A-
Stock motors don't have adjustable endbells, just removeable ones. Trinity released a stock motor with a removeable endbell in the late 90s, theorizing that it would actually save racers money if they could disassmble the motor and replace individual parts. Timing is still fixed at 24 degrees, and the removeable armature doesn't really make it any easier to cheat: Those old tabs holding the endbell on wouldn't be much of an obstacle.

Right, today's stock motors don't have adjustable timing, they're still fixed at 24 degrees(there's only one way the endbell can go back on the can, which locks the timing in place & even help make sure it's not installed backwards, which would really mess up its timing). Trinity introduced them a few years ago to make life a bit simpler for many of us, since now we can rebuild them just like we can mods(& most importantly, we can do it with a mod lathe, so you don't need anything special to work on a stocker). And about the 19 in your RTR & competition 19's, also right, a good competition-ready 19 will blow away that motor in your RTR easily(though it would be a good idea to have a selection of pinion sizes available, so you won't have one over or undergeared)... :cool:

Thanks for the responses guys I'll go dig thru the plethora of 19T motor threads and make a choice

ok so what pinions would be the best to get or should I just get a wide range of em and try?

I'd definitely get as many as you can, to maximize your tuning options(the high-torque motors will need a MUCH taller ratio than the high-revving ones do, but they all vary so much it's near impossible to just give out one ratio that'll work).... :cool:
