Video of Jim Ryan's 1/24th scale, tandem rotor Chinook helicopter. Video was shot at the VOA field North of Cincinnati prior to the Cincinnati Soaring Society's May Memorial contest.
The CH-47 is set up for DCP, and I have gyros for both pitch and yaw. In addition to the gusty wind that day, I was getting some radio glitches. In calm conditions, the heli is stable in pitch.
This is Jim, the builder. As for stability, bear in mind that it was pretty windy that day, and this thing is a handful in the wind. Pitch oscillation isn't normally a problem, but it's somewhat loose in the yaw axis.
Jim - Very Nice. Seems unstable around the elevator axis though. Does your setup allow for DCP (Differential Collective Pitch)? If so, I recommend putting a gyro (elevator axis) which keeps the heli level by applying corrections through DCP.
FUCKING AWSOME man damn!!!

"Chinooks don't fly, they beat the air into submission!" - LOL What a line! You should be a copy writer!
Great job building that yourself Jim. Twister have only just released a production model but have cheated by using a stabilized dual co-axle design.
