Always good to run across a fellow New England combat pilot! What part of Maine do you live in?
If you're planning on flying Combat in New England this season, drop me a line at
[email protected] for the latest contest info. Most NE contest dates are still in the planning stages. But, the North Eastern Nats will be held in Salem, CT on June 14th, Hadley, MA is usually held in Late July and Ellington, CT is usually held in ealy September. Bloomfield, CT might be able to have a combat contest this year. Several combat contests might be held in NH, but there are some changes going on with the folks up that way and we'll need to see what happens.
As for launching, underhand is the the method I prefer as well.

The transmitter is in my left hand (out of view) with the antenna pointed down and away from the plane.
To help with the "swing to the left from torque", try launching with the right wing down as shown. MUCH more managable.
