    That's pretty different. Looks like a flying portaloo. What's the name of this machine ? Like the rotor design though.

    The top rotor having to move a lateral distance could be the answer, this is how mine is different to a helicopter or gyro. In the air the machine pitches and rolls about its CG on the ground only the rotor tilts about its hinge.

    It doesn't have an overrun clutch now. However I can still do some investigations, i will do some testing and report back.

    It seems that way to me but helicopters and gyros would have to be the same for that to be true. If they aren't the same then then I'm confused again. 🤔

    Machine leading edge from billet aluminium ? 😉 That's the way I'd go but that's mainly because I have no clue how to build in any other material.

    Thank you. Crop spraying yes. 😀

    It's the same with or without the outriggers. The only conclusion I can come to is it's more weight shift than originally thought. ??

    Part 6 Something I'm wondering and can't quite understand. The tilting of the rotors while spinning close to lift off but still on the ground is hard to move via cyclic stick. Probably twice as hard than in the air, if the tilting of the rotors is 98% areodynamic 2% weight shift why is there...

    Can anyone help? Is this a Mini 500?

    Ha, Yes I thought you US people would think that. Different mind set I suppose.

    Can anyone help? Is this a Mini 500?

    Sorry for your circumstances, it looks a good project from the photos. I expect value would be the sum of the major off the shelf components. If you were further south I would be interested to have a look. Hope you find the right person to take it on.

    Watch this guy flying the Jetson ...

    There is some redundancy still being able to fly with a motor out and a ballistic parachute back up. I agree it will be available to anyone who can afford it. The advancement of drones allowed everyone to be able to fly them, the same technology applies here which is a concern. It's still...

    Thanks Kevin, you never know if people find the jokes you make on YouTube videos funny or not. Glad someone liked it ha !

    The latest video for anyone who hasn't seen it yet. I did about 4 days of testing, the weather was near perfect but it was only the last day where hovering attempts got suddenly better. I reduced over controlling by purposely under-controlling and what a difference that made after lots of trying...

    Thank you for all the advice! Great comments, they will serve me well. I've learnt so much from this forum. I haven't done any blade tracking yet as I haven't felt any vertical vibration until a couple days ago when I was in a brief hover and a wind gust caused some. I need to check the...

    I can see the logic in this, unfortunately sometimes you need more cyclic available. For example correcting a sudden wind gust. Perhaps it would work in an indoor environment ?
