Default RE: Finished my Ultimate Bipe

Did the maiden today. Pulled up the weather and it looks like high wind the rest of the week so I took advantage of the light wind today. On take off I allowed the plane to come up on step too much and I could hear the prop hitting the ground. Took it up high and did the trim work then came down and tried some stunts and just general flying. It flies smooth at about half power and doesn't have the vertical pull I'm used to, it's OK but it won't hold a hover very long. The loops were OK and the big stunt is the stall turn. The roll is the worst I have seen in a long time. It's more of a rollop. A very ugly barrel roll. Then I tried the outside loop, it doesn't like that at all!! At the time I was wishing I had more altitude but it came out of it OK.
Due to the weight and the linkage of the ailerons, it gets more throw from the bottom ailerons then the top, I rate this little plane as OK, nothing great but OK. I will be testing props on it though. I felt it was over propped with the 11 on it. My friends are using the 10 inch on the same motor/ESC combo but on a much lighter plane.
I managed to really shorten the prop on take off, over 1/2 inch!! But it still flew OK. I'm sure I can get it to fly better over time.
