Biker, I haven't flown mine with the stock wheels yet but I hear they are only good on pavement. They are to small for the plane. I didnt want to chance tearing her up on landing if a gear folds up so I ordered the Century Jet retract with oleo struts and a set of Robart 3 1/4" dia. wheels. The plane went to gether nice but for $200.00 I didn't expect a set of nice retracts.
