My son Lucas was able to maden his Alpha Sport 450 this past Saturday. We were able to get two flights on it. The first flight we handed the transmitter back and forth, which did not work so well. The second flight we borrowed a buddy box and cable which worked much better.

We are looking at the same airplane. Did you like how it flew?
Are the wheels large enough on the grass?
Scott,
Ya, it flew nice. We did put some 2 1/2″ wheels on it. It taxied well in the grass with the larger wheels.
John
Were you able to buy the wheels locally or did you have to order them?
Scott,
I have some 2 1/2″ wheels in my shop. But I think I was some Dubro 3″ wheels on the wall at Cobblestone. Also, I know they can order the 2 1/2″ ones and have them in a couple days. My 2 1/2″ ones seem to work well.
Thanks John.
