RE: Great Planes Escapade .40 ARF
The original main wheels are 3" and the tail wheel is 7/8"
The replacements I had to put on do to one coming off in flight are 2 1/2" ( please make sure you file a flat spot on the axel and use threadlock on the collar pins)
The tail wheel I used was a 1 1/4" wheel but keep in mind I upgraded the tail wheel assembly with the sullivan kit
As for the added weight from the upgraded wheels.....you WILL NOT notice the difference.
Good luck and Happy Flying,
Jerry
