RC Equipment: All other RC equipment should be installed on the dome under the canopy, where
also the hopper tank and engine ECU found their place. This support is 100% level, so it can be
used to mount a Gyro in the right attitude. It is advisable that you reinforce the mounting surface
with a plywood from the inside to stiffen especially the Gyro mount against vibration or G-load
movement during flight.
CG and Control Settings: The Rebel in general is very forgiving in terms of CG and control
throws. No bad habits at all. What looks right, most certainly is right.
The CG of all Rebels is the rear edge of the wing tube. This should be easily obtained with all
batteries installed in the nose, but it can vary 20mm forward or backward with no problem.
Elevator, aileron travel: 35-40 mm 20-30% expo
Rudder travel: 60-70 mm (20% Expo)
Low rates can be set to 70% of the above.
Flaps: 25-30 mm Take Off position, approx. 60 degree for landing, Down elevator mix
proportionally approx. 8-10 mm at full flaps. Use a 2-3 second servo delay function when
changing flap modes
A Cortex Pro Gyro would be set at approx. 25% gain when setting procedure is done with the
high rates as above.
A few words of caution, though: Avoid entering into a controlled SPIN with your Rebel. That's the
only maneuver it doesn't like. A recovery from a full autorotating spin, especially when the CG is at
the further back position, will take full throttle and several rotations! So better do not attempt it in
the first place, as it has to be forced very hard into a spin, it doesn't want to stall in the first place
- leave it at that!
