My 15th addition to my aircraft fleet is a Helicopter, the C186, based on a German (1970 present) Messerschmitt BO105. The real copter is an aerobatic flyer but this model is more stable like a drone. It flies with optical flow to help stabilise it (CORRECTION: this version does not have optical flow, hence the sticker), yet still it needs some inputs, probably due to the updraft it creates. There is a fair amount of air movement in my confined front room. I have flown drones that are more stable.

Had good fun though. 1st flight was a success although short. After that whilst trimming I managed to hit my settee a couple of times. I tried it outside briefly but it was too windy with 16mph gusts.

This is a flybarless machine meaning it does not have a flybar for stability as this would be unsightly in a scale model. This is an addition rotor style bar under the main rotot used for stability. Instead this machine does it electronically with gyros etc.
