A Few Questions*

[Stampedeguy]

I am thinking about getting a trinity speed gem diamond 12t motor for my RS4 rally. Is This a good motor? Also what size spur gear should I use, I want speed. Also what do you guys think about the Associated IPC forward only ESC? I Am going to take the existing motor from my rally it is 15t and put it in my stampede, is this a good esc?

1. the 15T in a pede is an awsome choice, i had one in my Pede
2. im not a gearing expert but try maybe a 16-18 tooth pinnion
3. never used the ESC so i dont know

I heard that 17T motor is the best for a RS4 rally. It just not the fastest. If you have the extra cash get a D4 instead of a speed gem. The same turn motor will still go faster. I myself have a 16T speed gem because I only had 25.00 bucks for a motor. I didn't want to wait to save the money. Go luck with you Rally car. I would try to get a set of pinions. This way you can go fast or try a lower tooth pinion for more torqe and acelleration
