Robbe BK117 Gyro replacement and test flight

I can no longer adjust the sensitivity of my GY401 gyro. For this reason, it needs to be replaced. Luckily, I have a repaired one that had the same problem.

Beautiful. You are like the Chuck Yeager of test flights. I had a Robbe Md500e with Fututa SE mechs. I sold..one of my regrets in life😢

Yes, the size is impressive when the helicopter hovers next to you.
