Well finally got my little project finished and all i can say is wow! its faster than I expected it to be :)

I've got a 9920 with 540c 8xl. So far have only been able to run on 12 cells and its a lot faster than stock on 14!! but i have a few observations.

The grub screw on my pinion continually came loose which was a pain to fix in the field. Not a big drama to fix and I figure some loctite will sort it out but is this normal? i did it up pretty tight and have a decent notch on the motor shaft.

It cogs quite a lot at low speed on the 12 cells, the batteries I have are gp3300's (the others are IB4200) Once i put some throttle on it goes away and I havent yet tried on 14 but should this be expected on 12 cells?

Recommended slipper tightness? I've tried a few settings tight then back off 1/4 turn and also 1/2 turn but it will flip far too easily, either with wot or hitting the brakes. will loosening soften this effect like it did with the stock slipper or will the power just mean i shred the slipper pads

Brakes. The brakes on the 9920 seem pretty much an instant reverse and not very gradual like with the evx. I followed the programming instructions in Mikes sticky thread. Is this normal or should i reprogram to get more granularity in it?

I cant wait to get this out for a run with the nitro boys :)
