Go to rcuniverse.com and then to "Electric indoor and Micro..." and then to "Air Hogs Aero Ace" and p54 post 1351. Not such good pics yet - too far away. But you will see the wheels at this stage. I think that the weight might be a bit too high to get a rolling take off and so I might sand the rims narrower. (leaving the axel to have a wider contact to avoid tipping of the wheels on the axel - I'll sand from the inside to maintain the max spread between the wheels) I will also probadly make the axel wider since the plane tends to be tippi on rolling takeoff. As far as I know you would have to buy a new hot wheels set at a toy store. I have never seen track separate. I am working on a wooden track piece that might work but that's gettinga bit ahead of the story. The balsa spacer piece (or foam piece) to hold the wheels is about 3/4 '" (20mm) wide to go between the wheels and about 3/8" inch (10mm) high. Just a bit more then 1/2 the wheels diameter to clear the planes undercarrage. If I widen the wheel spread that will change things a bit.
