Hehehe! Way to go!
Out with the Nitro in with the new. Brushless is deffffinitely what it's all about now.
Great job on the cut-outs there! Personally, I would recommend a single screw 'pivot' hole and radius slot, due to the extra power. I reckon you've built a wheelie monster there! Motor nice and high, Lipo batteries to keep the front light, job done!

Put a wheelie bar on it!
I converted a Hot Bodies Lightning Stadium as soon as it arrived from good ole ebay. I've never used nitro, never will.
