hyper h2 gearing help
 

hey guys i have a hyper h2! id like to run a 7.5t or a 10.5t motor
what pinion size should i be using. anyone got the fdr on these and pinion sizes they use
thanks for any help

24t on a 7.5 works fine for me, maybe a 26t for the 10.5

I use a 21t but with an 82 spur on a 6.5 works well enough.

thanks guys forgot to mention that the track i run on is dirt starts with a light dust coat after round 1 the grip comes good
i did notice the setup guides that have been posted suggest 24 with the 7.5t
also is the pinion to spur ratio the same as the tlr 22 is that a good guide

Fdr
 

Im sure the fdr is the same as thr tlr.

The geared diff main gear is 51t the same as the ball diff in the tlr.

The tlr ball diff including its outdrives drops straight in the grarbox of the hobao as i have done it just to try it out.

I had a 7.5t and 24t pinion with kit spur is spot on.

the tlr diff is actually 1 tooth less

Where did you get the 82T spur from?

I believe it was a losi spur, its a white one. One of the drivers let me use it as it was the only one that fit. Think i had to shave the hole out a bit but it works fine.
