Hi,
After all the mishaps that I have had with models, I'm not sure I would get into a full size, although they look pretty safe.
You guys in Finland have it made. You just crash in the snow and pick it up and fly again.
My gyro looked like yours in the video only worst. I installed a new electric motor on my little Rotorshape and tested it several times in the shop with the power analyzer. I'm using a prop saver, the one with O' Ring holding the prop on. I knew by the sound on the first flight the O' Ring was holding well enough. So put on another O ring. This time that little motor had so much torq before I could do anything it went straight up into the sun. You guessed it!
] Couldn't see it and probably couldn't have done anything about it anyway.
That is one of the problems with a DC gyro. Without a conventional elevator you just can't get the nose back down. Anyway, rebuilding for tomorrow and good luck in the snow stay safe with that full scale.
