I built mine in 2000!!!!!!!!! Could it be?
On my maiden, I recall not much ground run and "popped" it off and up it went. After that, I was getting too much ground run and tryng to take off in a more smooth fashion. it was not good. No steering on the dolly of course and the plane would slip off or tip over. So I went to hand chucking it. Plane is still alive and well
