After a year of just looking at the Sundancer after building it, I got the courage to fly it. I fly off of a grass field and it is a bit bumpy. The plane wants to nose over unless one uses the elevator on high rates to keep the tail firmly planted. On the first take off attempt I let the elevator stick spring to neutral after leaving terra firma only it was trimmed with a bit too much down ... and the plane came down fast on its belly. All that happened was to bend the landing gear (almost flat)! Nothing broken! I re-trimmed it on the ground and put some expo in. The next flight went like a breeze .... except one of the screws came loose that holds the landing gear on and the landing gear was askew. So after flying for about 15 minutes, I landed in soy beans. Again no damage. The next day I flew the plane and really like it. It is very stabile, easy to land (except for nosing over) and it does great general aerobatics. I found no restrictions climbing straight up either. It just seemed to go. The YS 63 turns 12,000 rpm with a 13 x 4 W prop which helps the plane slow down too. I have had NO problems with this engine and run it on 15% with castor. If you like biplanes and have the room to transport it assembled, this is great plane!
