AVENGER Reflex Tips
There's a very simple indicator to determine if your ailerons are reflexed
the correct amount.
Here are the steps and a simple illustration:
1) Get your AVENGER trimmed to fly straight and level.
2) Fly into the wind at full power and quickly pull the power off.
3) If the nose dips quickly when the power is removed you need to reflex
your ailerons. Two turns is usually enough and a good place to start.
4) Continue these adjustments until is just coasts with the power off. Now
you'll have plenty of elevator authority to grease it in on landing
