Larry - the WH giles you built for me (the RCU giles) also did the same for me on a paved runway. It just didn't want to come down. I attributed it to the idle maybe being a bit too high but not sure. I have to get more flights on it to get a better handle on it. Only flown it a handful of times due to time constraints and non-cooperative weather in the last year. There was another WH 35% giles at the sussex show that I flew at that also did the bounce thing. Somebody at that meet told me they heard this was not totally uncommon with this plane. I still would guess if you bled off the right amount of airspeed and got the idle low enough it just would stop flying. It does weight over 20lbs afterall
