That's easy the "FTW Nanofox" body. Absolute beauty. If I was running RM I'd be all over it.

I run the finisher MM but I'm sure it would look just as sleek in RM. My pops runs the LW kyosho lid and it looks cool.

I just replaced my gearbox, bearings, top shaft and pinion. I made sure everything was super free in the gearbox and that my slipper was set so that it barely raised the front wheels.

Right now I'm debating whether it is spur gear #8 or b5m #1
It sounds like there is something else wrong if you are going through that many spur gears. May I suggest you set your mesh and then have someone else look it over, including rotating the gears.

No matter how experienced one may be it doesn't hurt to have someone else take a look at what you have because even the best ones get blind eye once in a while.

Okay went to the track today, and I got the car to come a long ways. But still isn't very good...

Here is a picture of my setup sheet:

The car like this is decent, but surprising as it sounds it still is lose in the rear. I'd say it has enough steering (not to much but enough), but still needs more rear traction. Also to kinda explain more, I feel it needs more on power traction, and maybe more off power also. Was going to stay after and practice but their rebuilding the track.

I have yet to try it like this, but I have the aluminum pivot as well as could run a wider rear pivot to free it up on power if I need to I think.
