toward precision aerobatics then I recommend setting your CG using the 45
degree line test. Fly the aircraft from left to right or right to left, whichever
direction you are more comfortable with at 3/4 to full throttle. Pull the
aircraft to a 45 degree up line and establish this line and immediately roll the
aircraft inverted. Establish this line and let go of the elevator stick. Ideally
the aircraft will continue to track on that 45 degree line for several hundred
feet before slowly starting to level off. Adjust the position of your battery to
achieve this flight condition. Once satisfied with the location of your CG
scribe a mark on the battery tray so that you can position the battery in the
same location each flight and achieve the same feel and flight characteristics
each flight.
I also highly recommend taking the time to properly set up your rates and
exponential settings. Setting up low rates for precision maneuvers and high
rates for aggressive aerobatics and 3D flight will allow you to experience the
best attributes of the Extra or any aircraft for that matter
Here are some suggested rates to get started with. These are the rates and
exponential values I feel comfortable with. They may feel awkward to you
and if so please adjust to your taste.
Elevator: Low rate-8-10 degrees; 15-20% Exponential
3D rate-45-50 degrees; 50-70% Exponential
Rudder: Low rate-20 degrees; 45-50% Exponential
3D rate- As much as possible; 60-70% Exponential
Aileron: Low rate-15-20%; 40-45% Exponential
3D rate- As much as possible; 50-60% Exponential
Thanks so much for your business! See you at the flying field!
