After another 10 hours flying I checked the plugs again. They were on the light side of tan- not too bad but I like to see them browner than they were. So I have set the needle clip on the second slot down- midway between Hirth (top slot) and FC (thrid slot). I will check the plugs again after a 1-2 hour flight.

Just to clarify in case you thought I was missing something obvious like the fuel level sightglass strip up the side of the tank- My Nano has a larger 30 litre tank and does not have the sightglass strip. So my only means of sighting fuel level is through the seatback inspection holes.

Further update- Fusioncopter sent me an stl file of a camera mount they use. I 3D printed it and tried it out- works well. It allows a relatively unobstructed view of the flight controls, EFIS and suroundings. Perfecto! Thansk Fusioncopter! I need to firm up the mount- it was only softly clamped in this test- and permanently wire the camera 5V supply inside the side canopy hoop to keep an uncluttered cockpit. A sample video is here- https://www.youtube.com/watch?v=A60hxbm8QG0

A video of 3 landings at the local field. https://www.facebook.com/1034764558/videos/918836509095280/ The nano is super easy to land gently- it just floats along at 20-30 kph in ground effect.

I have posted another video- a bit shorter and tighter editing this time! Aim was to better understand my take-off technique and also try a head-mounted camera. The video is here> https://www.dropbox.com/s/26mqze9e08339go/22.10.2022%20HOME-NZTE%20head%20mount.mp4?dl=0 The head mounted camera is not a good idea- The canopy hoops obscure the view-almost as bad as my head with the bulkhead mounted camera. With your head on a swivel checking traffic, instruments, and generally enjoying the view- the video is too 'busy'. Next flight I will try a chest mounted camera position. Re take-off technique- Above 3000 engine rpm my brakes start slipping, so I normally just go with the flow as in the first take-off in the video. The second take-off I held some back stick above about 200 rotor rpm so the rotor was helping the brakes hold. It felt more in control.

My Nano has arrived in country (NZ), just waiting for release from customs and get it trucked to my field. Great birthday present on its way!

If you always have the trailer there while fitting/removing the rotors, a simple rope/pulley system off the top of the trailer door would do the trick? It also looks like you are using split pins on the rotor nuts. Would safety pins be simpler/reusable alternatives?

Hi Jeffrey- How is your flying going? I have been hanging out waiting for your next youtube video to satisfy my aviationitis till my machine arrives (on ship now, expected late June). Replacement bolts already? Or are these hot spares for further down the track? Stuart.
