Flybear FX 820 SU 35 2 Channel RC Airplane Flight Test Review
This 2 channel RC plane is shaped the SU-35 fighter aircraft.
Pros
- Good looking fighter airplane shape of SU-35.
- Simple two channel controls of throttle for climbing/descending, and yaw for turning right/left. Yaw turns are accomplished through differential thrust of its two motors.
- Common 220mah battery with white Losi connector. Should be able to easily find spare batteries.
Cons
- The instruction manual claims gyro stabilization. However, phugoid oscillations and roll over with hard yaw suggests that this may not be not true.
- Calm day flier only. Not for windy days.
- Yaw turning control is only slightly proportional. Best truned with short multiple bumps on the yaw control until the aircraft is flying in the desired direction.
This airplane was made of 5mm and 10mm depron foam , balsa wood and plywood, carbon fiber rods for the wings mount , white vinyl and all the stickers were cut in a plotter machine
