What motor are you running?

damo77 29-01-2014 08:05 PM

24t is standard. I run 21t on both of mine with standard 78 spur and lrp 6.5 motor

I have a 21t but my hobbyking 13.5 won't move all the way over so won't connect

damo77 29-01-2014 08:56 PM

it should do. ive had a 20t on mine, unless it has a smaller spur fitted. see what size the spur is. I have a standard spur or a 24 pinion if you need them. I found mine over geared on 24.

ive just checked the spur size. its 76t standard not 78t

adon30 29-01-2014 09:31 PM

I run 25t or 26t on a 7.5T hpi and think I had 27t on the 8.5T

Not sure on a 13.5T but the kit 24t may be a good start.

I'm running my H2 rear mount in the stock 17.5 class and I'm struggling for top speed. Running a Speed Passion motor car just seems to run out of legs halfway down the straight. Using the stock spur with a 30t pinion. If I use a bigger pinion the motor becomes to hot and it lacks low down punch to get over the double jumps. Guys in my class with the Losi 22 and the same motor seem to have more low down and more top end punch:(
