jangodog
If you are using 'safe' it is vital that the gyro is calibrated to tell it what 'plane level' actually is. This is the attitude the gyro will try to return the plane to when 'safe' is...

Given all the mechanical parts and cylinders are steel you can understand the weight but nevertheless a wonderful example of the machinists art. Just count up the number of ball bearings required!

I must agree with Solentlife.
For a specific airframe the power to fly is directly proportional to its weight. Add 10% more weight and you need 10% more power. If the extra weight creates more drag...
