Actually the pics look good. I'd move the front wheels back a bit to just in front of the on-off switch. I'd add the tail wheel to the strut. You can twist it a bit to get it to line the plane up streigth for takeoff. If you use hot wheels track to control take off you'll be fine. The wheel and axel set is hard to remove. I had to use a small chisel and hamer it free - on the set I took off of the car's undercarrage. ( I have not yet tried the wheels left on a pieceof the cars undercarrage - it's windy out today) The spacers I have used are a small piece of balsa that fits just inside the axel length and is just thick enough to have the wheels clear the plane's undercarrage. I also used a piece of fairly ridged foam block to do the same thing. I don't know if one is better then the other but the balsa is easier to shape precisley.

I'll try to get some pics up later.
