I've followed the history of a certain Bel Air biplane, built in the 90's, black with silver darts and excellent Monokote work. This plane was built per plans by a local here, won a Monokote contest, flew a little and was sold to another club member. With a Magnum .61 this thing was a rocket and had a very high roll rate.

This club member sold it to yet another, who enjoyed it for a while, and sold it to one of my students. The student tried it, with me on the instructor box, and found it a bit too sensitive for him. He has put it aside, and will spend some more time with more docile planes.

I enjoyed the trim flight and letting the student have control for a bit. Even with mild rates, it was pretty sensitive in roll. Very responsive all around, and quite fast with the .61 twostroke.

Having flown this one, I wouldn't need to change the ailerons for ordinary flight.

Good luck,
Dave Olson
