I just wanted to ask for some opinions---

I just installed a GTB 4-cell with a 4300 motor in my TC3 and am running 6 cells with it and was wondering what kind of temps are too much for the 4cell GTB ( I have a temp gauge but I only took the car out for 10-12 laps to see if it felt ok). I went just a bit higher on the gearing that the SS speedo reccomends for the TC3 with a 4300 motor (the manual advises 23-24 tooth pinion and I used a 25 tooth pinion as the track I run on is basically an oval with one jog in the backstrait with a little less grip than ozite).

I know I should have stuck a 6 cell GTB in it but I was being lazy because the 4cell version was already in the car(was going to set it up as a VTA car).

Let me know what you guys think.

Thanks and later,

Mark

I actually ran a 4 cell in mod truck with an 8.5 on a li-po 3200 pack and had no temp issues as long as I ran a fan

What kind of temps are you getting? If its only gettin up to maybe 110-120 then you should be alright. If it goes higher, i would put a heat sink and fan on it.

Does your 4300 have the bonded or sindered rotor?

WHat is the difference between the 4-cell and 6-cell gtb?

6 cell has a larger heatsink and a fan. Also, the 6 cell has plug in harnesses for the switch and rx leads.

4 cell has a flat plate heatsink and the wires for the switch and rx are soldered on the board.

Thanks for the responses guys.

CClay---Not sure of the temps yet (I just ran the car for 2-3 minutes to check to see if everything "felt" alright.) I will put a full race length (4-5 minutes)on it this weekend and will check the temps then on the esc and the motor. BTW---Do either HT North or south carry the BRL heatsink?

98Ron---Not too sure as the car is not with me at the moment but I think it is the sintered rotor as the guy I bought it from is a oval racer and also works at a hobby shop so he probably didn't go the cheap route. Not that it matters though as the place I race at runs TC open as in any motor any battery and last year I finished 2nd in the points with a 13.5 and 3300 6cell packs, so this is just one step up in power and hopefully enough to move me up one spot in the standings.

Neither Hobbytown has the BRL covers. I havent really checked out where to buy them, but they should be available on-line somewhere.
