Thanks, it reminds me of the old GLH, just different without the screaming TD up front. There isn't any difference to speak of between the AP and NORVEL, I would guess the plane was going 45 up wind and 65 downwind? I could try a TD on it with a 4 pitch prop [on back plate pressure] to get some speed out of it. It seems fast enough right now for lively sport flying, though.
