Great idea with the grommets. Even if the little grub screw backs out no chance of loosing your wheel. Excellent idea. Actually it looks very similar to the RC8T hex setup. They have a round spring clip that does the same thing. I wonder if it's same diameter. That would look factory. I have quite a few of them spare. I just need to find them.

I just wish I had the time to get in my garage and play with the toys a bit. Work has been a killer at the moment and leaves me no time for RC at all. I have 3 brand new toys sitting in the garage that I haven't had a chance to use at all. Really sucks.
