Thanks for all the replies.
Yeah I'm aware of the GRPs but they're so small and look stupid on a Talion lol.
F/R diff weight is 50k/30k.
I've gone down to 500k in the centre but not tried it yet.
Its probably to do with my setup. I do have a steering gyro which is built-in to my Radiolink rx, but I don't know how to set it up. When I activate it, the wheels just wobble and becomes very unstable.
It could also be to do with the face that I'm running an SSS 4092 & Max6, even though I've got a 22T pinion on there it's still pretty powerful. Temps never get above 45C though...
Sounds like its your gyro gain being set too high. Upgrading to a faster servo will help but I'd turn the gain down before I did anything else..
