Brushless Gearing! Help!

Ive bought a 6.5 motor that isnt quite here but not sure If I can run the stockm spur (81 teeth) with a 17 tooth pinion, does anyone have this combo or does it not quite reach?

josh, when i race my lrp 5.5 at the club i normally race an 81 spur with either a 18/19 depending on the track, But i turn my throttle curve to about 30-40 so it doesnt get to warm

Does the 18 fit well. Im thinkiing 17 is a bit low and 18 would be about right. Does the 18 tooth get far forwrd enough to mesh good?

What i found is that the lowest you can go with an 81 spur is a 17 tooth pinion. A 16 just wont move far enough

Cheers, think Ill go with the 18. LRP/Nosram say 12.4 for a 6.5 in 2wd and with the 17t it would be 12.39. But lookign up people are using 20t pinions on 5.5s! So i think a 18 would be about right for me. Speed wont be an issue if you saw my car at Bury, I need some!

I've got a 6.5 with a 19tooth pinion on the 81 spur.. no problems. But i am running lipo so it's got the power to push it..
