jammin x1 crt gearing

[riverat1540]

you are geared for 47mph on 4s and 60 on 5s not including tire ballooning, i think your system is under too much load to get up to speed if u think it is too slow with a 17 tooth pinion and a 2300kv motor, i used a 14t pnion on the 62spur with factory diffs on 5s and neu 1515 1y geared for about 46 and it was plenty fast and was not under alot of stress , cool running setup. also the reason to use a smaller pinion with such a large spur is that the crt x1 has buggy diff's in it and does not use the truggy diff ratio which is why it uses the large spur.
