Hi Ted,
I was the pilot and typically end up about in the middle of Advanced, flying a classic airplane with classic power. No expert by any means but on a good day I have been told I can fly a pretty respectable pattern. The day the tank video was shot we had a 12-15 MPH wind and it was by no means a 500 flight but all the maneuvers and corners are there. The only places I fudged were the reverse wingover and the exit from the clover. Just as I was climbing vertically out of the last loop in the clover I felt a pretty good wind gust so played it safe and did the wingover into the wind at about a 45 instead of 90.
I am not sure I know how to explain how the TwistMaster handles the extra weight and drag of the camera system. It wobbles a bit more in tight corners but other than that I really didn't notice much difference. It doesn't fly "heavy" like the Bipe did and would still go where I pointed it. I didn't see any real difference in the effect it had on the TwistMaster verses the Magnum. I am convinced the switch from a Saito 30 to a Saito 40 had allot to do with it's ability to handle the extra weight.
How about this deal, email me your address and I will send you a tape, if you like it send us $20.00 if you don't just send it back.
