Kallin,
Brilliant thank you very much for the pictures they helped a lot. I have found the Varioprop on the German website and intend to go the 4 blade route. Do you get any damage to the wing around where you put the batteries when you go inverted, as they seem able to move in the vertical, or do you put foam on the wing? Mine may be a little lighter due to not having the sound system and my 3 x 3600mah(1 retract 2 powersafe rx) batteries are placed in the ready made battery box if the C of G allows. What flight times are you getting with your set up?
