Tom255, that is a nice setup, fantastic fabrication work. I don't quite have the machining resources you do so I have to keep things pretty simple. I was thinking of doing the nitro type mount with the slotted holes for adjustment with a Mega Motor but since I have 4 feigao's laying around I decided to use them instead with a regualr endbell mount.

Sparky, that is one nice buggy. Very creative regarding how you handled the braking (ESC and mechanical). Very clean. I think I will go with the dual (front and back) mechanical brakes for now, and if that doesn't work out your ESC/Mechanical brake solution sounds very interesting.

On the battery tray, I am using Maxamp lipos, and they are good packs for the money. But they are a little fragile. The indivdual cells are not bonded together so under hard impacts they can slide around within the shrink wrap which distorts the pack and can rip the tabs off. That is why I don't just strap/velcro them to the chassis, which would be light weight but would not secure them enough for my needs. I have since taken my packs apart and bonded them so they should be more durable, and I may go back to strap/velcro only in the future to loose some weight.

Thanks guys for the great feed back, that's exactly what I was looking for.
