Hi Duke,
Ray and Woody have spoken of you often. (In nice terms of course). Thanks for the pointers on RC Groups. I am going to have a bit of a moving CG issue as the plane I need to put the gyro in has wing that sweep, roll control is via spoilers and tailerons and there are some variables in performance that I am still uncertain of. Ray has been looking at the original aircraft's behavior and has given me some good tips, but this does not always manifest itself in the model.
The Raiden was around 1/5 scale. I built it around 7 years ago. It has a twin cylinder 64 cc gas engine. It flies very well, take off and landing require careful elevator control to avoid nose overs. Prop replacements seem to have taken place on several occasions.
