Thumbs up proper gearing

i was wondering if anyone could tell me what the proper pinion gear is that i should be using in my associated t4. i am running a novak gtx speed control and a co27 pro stock motor by trinity with team orion 3400 lipo packs. the spur gear is the stock spur gear that comes with the team associated t4 race spec. i also wanted to know what the best temperature is to run it at. thank you very much to any one who can help me and give me the right information.

It really depends on your track, but I geared my co27 with a 19 tooth pinion. The rule of thumb is to keep gearing up until the motor starts getting close to 180 degrees at the end of your race. For me at my track it happened to be a 19 tooth.

Also depends on your driving, better drivers can use a bigger pinion. They carry more speed through the corners and crash less, makes it easier on the motor. If you are not yet running nice clean smooth laps perhaps start a tooth or maybe even 2 lower. Good luck!

Between a 19-20 would be a good starting point but you might have to gear to your track. I never geared my motors to get over 150 degrees, over that it put more wear on it faster. Dave H has a good point also.
