this should be an entertaining series! Haven't had a chance to watch most of it yet, but I've raised an eyebrow!
That looks like a Darwin Award waiting to happen!
No sense of self-preservation from the onlookers in video 1 either - where do they think all those whirling bits are going to end up when he rolls it over?
He has already had one lesson in an R22 - he mentions it in video 2 - so why not go and learn to hover properly before trying out your home built death trap?

He doesn't even turn the nose into the wind.

I see it's got fixed-pitch rotors too - no thanks...

I saw 3 "episodes", can't find any more. Bad omen..? :sad:

I saw them too, seems to be tail heavy even with the weight hanging off the nose. With it being tethered to the group with a 1 ft leash not sure he'll ever fly

Not necessarily, the last episode was posted on YouTube just two days ago so there might be more in the pipeline.
He mentions the RRPM is 730 in the hover - I wonder if he has thought through its ability to autorotate, the blade area is small (hence the high Nr required to generate lift) - how is that disc area going to provide enough auto force to keep the rotors going when his engine stops?
And since he doesn't have a collective, how would he cushion the touchdown?
Definite Darwin Award territory.......

I don't think it would be achievable - if you've got enough pitch to actually fly with variable rpm only I doubt you'd get enough airflow to actually drive the blades? Kinda like trying to do an auto with the collective fixed halfway up - might get away with it if you were low, fast and flared all the way in!
However, in the chap's defence he's quite open in the comments about only aiming to get the thing to a few feet and hover taxi about. So if it's going to be horrendous, it'll be because fast spinning machinery has gone wrong!
