you cant do over a 39/18 pulley for short belt.
anything bigger wont fit on belt.
use.
39/16
22/14
39/18
equals 77%
or
39/15
21/14
39/18
equals 80%
good to start with and can get using CS pulleys

39/19 still can use the short belt . You need to switch the hex bearing holder to the correct position.

hmm.... how to remove the big pulley to change the pulley?
need to "force" ?

RTECH

There is a long allen key screw inside the "cups". Loosen it to remove the big pulley.

+1 39/18 is the biggest you can go. 19 is very tight and puts stress on your rear drive.

Hi bros,

Been facing this problem with the OTA R31: front steering rack seems to be vibrating when turning no matter how much I grease those parts which have to be greased. anyone has any idea how to solve this? does aluminium wheel hubs play a part in this?

btw, anybody has a good servo to recommend? preferably a high response one. I understand that KO Propo has different versions. anyone can guide me on this?

hi,

just wondering if you guys have any feedbacks of body shells not fitting nicely into the R31 chasis?

I have some difficulty fitting in the HPI Rx7 body shell
