Gaui NX7 - Maiden and second flight (Flights #1 and #2)

Maiden of the NX7

I had some motor issues (hence the short 3 minute flight) as the motor is running rich (not helped by me richening it up two clicks before flying) but ended up with the glow plug dieing.

Replaced the glow plug and the replacement was a dud, so replaced it again and this one was OK.

I ended up leaning the high needle off back the original richening of two clicks then an additional two clicks. This helped a lot, but it is still running really rich, so may need some more.

There appears to be some vibrations throughout the heli, so will have to strip it down and balance everything again.

RIsto also suggested that I may need to add an additional bearing on the torque tube to help with vibrations.

The RPM telemetry was nice to have. Will leae it on there as it will help with trying to diagnose vibrations.

I also dialled down the gains while I was at the field. Haven't flown it with these settings yes.

Two little flights of 3 minutes and 7 minutes
