Gearing help RC10B3

[2500M_Sub]

Awesome, I installed the new motor and speed control last night, got the body painted over the weekend and should have the radio, battery and charger early next week. My wife got me the remaining items. I asked for another battery and reciever for Christmas though in anticipation of using them in a gold pan car. I popped off the gear cover and realized I had a wierd 18 tooth pinion on the motor. The body is metal and the gear teeth section is yellow plastic. Must have picked it up at the lhs back in 97 or so, maybe it was hightech back then? Guess I will start with that and maybe try something in the low 20's.

Regards,
