Fair enough! It is probably worth following the RR2 thread on GTM to see if anyone is having problems with each bleeding edge build before trying it.
I've tried it, putting the forks on two gearboxes. The first at 10-0.1 and the second at 10-0.5. The forks move at the right speed, but they're completely useless.
If I try to lift them with any weight on them, they just go limp and fall back to the floor after about half a second.
