Re: Gaui X3, max speed only 724 km/h?

can the helicopter fly faster than its tip speed? 0.8m x Pi x 2900 RPM x 60 = 437 km/h - Max safe Forward Flight speed estimate = Tips speed * 0.3, before the onset of uncontrollable cyclic handling from retreating blade stall (violent 'pitch up' effect 90º rotor offset to retreating blade), may occ...

Re: model mass

If the model feel lighter, could that be a factor of the "infinite" battery? This would give unlimited power, unless the battery current was limited, by the internal resistance of the battery The recent addition of Goblin 380 it seems like head-speed is more load dependent than most other models. I'...

Crash the tail rotor and keep flying in a circle, there is no speed limit?

Other models do not behave like this.

Autolevel

Quite a few different flight controllers (Ikon, Vbar6.0, Bavariandemon, MSH-brain, Skookum, Naza) now have an autolevel/bailout function, which is why all these DJI's fly around.
Would it be possible to add this function, to keybaoard or a switch?
