I've got a really old car.... a Kyosho Pro-x... it started out as a buggy but I enlarged the front forks and replaced the 3" shocks with 4" ones. Kinda fun having the extra ground clearance.
I also fly planes. Been flying for a little over a year now, and I think this is my 4th or 5th plane. I slightly overpower my current plane with a Supertiger .51 ... nice engine
I also have a small electric pylon racer... runs off a speed 400 motor and about 7 cells. No where as near as fast as my glow engine, but still kinda fun.
