Set-up and flight tips.
CG range for the Extra is from the front of the wing tube to the back of the wing tube.
Use the wing tube socket in the wing root to determine the location and transfer this
position to the bottom of the wing using a felt tipped marker. CG is determined with
the Extra in the upright position. Correct CG should be easy to achieve by moving
the battery along the length of the battery tray. Adjust to fit your flying style. One of
the best ways to dial in the proper CG for your aircraft is the 45 degree line test. Fly
the aircraft in front of you from left to right (or right to left if you prefer) at ¾ throttle.
Pull the aircraft into a 45 degree up line and establish this line. Roll the aircraft
inverted, neutralize the elevator and pay close attention to what the plane does.
Ideally the plane will continue on this line for several hundred feet before it starts to
slowly level off. If the airplane immediately drops the nose it is nose heavy. If it
begins to climb inverted toward the gear it is tail heavy. Adjust the battery position
until you determine the proper CG and mark the battery tray so you can place the
battery accurately each flight.
Control surface recommendations are as follows:
Elevator- 10 degrees low rates, 45+ degrees high rates.
Rudder- 20 degrees low rates, 45+ degrees high rates.
Aileron- 15 degrees low rates, 35+ degrees high rates.
Use exponential function to achieve the best “feel” for your particular flying style. I
highly recommend that you take the time to set up rates for precision flying and
separate rates for 3D. The Extra is capable of flying very precise maneuvers, and
proper rates and CG will allow you to experience this to the fullest extent. Trying to
fly precision aerobatics with 3D rates is an exercise in futility. Spend some time
dialing in and trimming your plane and you will be rewarded with a great flying
experience.
Thanks again for your business!
See you at the flying field!
