sscAVENGER 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 sscAVENGER 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
