Can i fly it indoors?
Budgevheli
Give it a go and video the experience for us, but i should maybe hang in my 50 Norwegian Krone here. I would definatly be wearing a helmet, as you never know whats going to hit you in the bonce once inside, and if your barn is not as big as what Devil 49 suggests then you may be wise to get an extension on your barn before trying, or it could end in tears.
Vfrpilotpb i don't think rule 5 counts for inside buildings....does it?
Let us know how you get on.

And all most of you can do is rant on about how you would not fly in it. No one is asking you to! Just because you have a bigger chopper does not give you the right to criticise someone with bigger b***s than you.
Thomas Coupling has been the only one who said anything about not being keen to fly it. And that was fairly light hearted and followed it with sensible comments.
I thought in all every post has been either supportive, sensible or informative (or humourous).

Can I hover indoors
Thanks for the feedback so far. I realize that when you post on prune, you have to be prepared for all comments, so no problem with a bit of urine extraction. As observed, this is not the first machine that I have built. MK 1 Bug hovered on tethers but had insuffient tail rotor authority. It was powered by a 500cc Rotax. MK 2 Bug was a development from MK1 this time powered by a K series BMW unit. the carbon composite boom and belt drive system on this machine proved to be unreliable. MK3 as you see in the picture, is almost ready for a ground run. When I raised the question of testing such a machine indoors, the man from the CAA could not give a positive answer. I was therefore interested in Pruners comments. Regarding the effects of turbulence when operating a rotor system indoors. I have conducted a series of tests using a fifth scale rotor test rig in an enclosed enviroment , and feel confident that the feedback rate of rotor induced turbulence given that a seven to one ratio of rotor span to barn space is observed, even I as a NON RATED LEARNER can handle . Should Buggy not post on Prune again you will know I got my sums wrong. ppheli this machines got a bigger kick

Bug,
How many rotor diameters is the barn roof above you?
I heard of a case a couple of years ago when a guy with a Rotorway tried something similar and created suffiecient pressure drop under the barn roof that it callapsed on top of him...BEWARE!
The other point to recall is that the vortical wake underneath a helicopter in the hover is unsteady and persistent. Therefore, the turbulence that you experience will get worse the longer you try to fly. So if it gets hairy, put it down sooner rather than later.
As with a couple of the other guys my advice is to run it outside - less variables and will be easier to handle.
I hope all goes well! Tally-ho.

One would hope that an Englishman's home (barn included) is still his castle.
As such, one should be at liberty to indulge the darker aspects of one's character; whether they be Morris dancing, starting a Lu Zuckerman fan club or even the flying of a kit-copter!
Surely not even the U.K. CAA have "Authority" over the airspace in one's abode
Maybe Flying Lawyer can assist with this point of law (assuming he's not too busy listening to "stories" about Bolkows falling off the back of ships. As if!!!
)

might be safer to fly it in a fenced off area (to catch the bits) rather than indoors with all that recirculation.
As far as the legality goes who knows. I would say it's your barn, your machine, etc. might want to take some precautions wrt to medical and fire. Get some extinguishers and hire St Johns.
(I think they give you a murray mint for broken bones) at least then you can say you took precautions etc etc
The web cam is a great idea.

Chopper Chopper Chopper chopper
Several years back, at the HAI there was a machine you could attach to your helis to keep it under control - semi tethered. It would allow you to yaw as required or control it if possible and allow you to hover at about 5 foot as well. Without the chance of rollover or tail rotor strike etc. You seem handy with your hands so a version of your own would seem easy enough to make!
Good luck, and yeah..... film it.

Hmmmm
As my Mother would say looking at it pondering.
' Just be careful, and give me a call when you arrive'.
Have fun brother, good on you for having a go and I take my hat off to the size of your Kahunas....I think !

MightyGem is right, Hanna Reitsch did it - in the Focke-Achgelis, in the Deutschlandhalle in Munich.
She test-flew before they let the punters in and all was well, but when the audience filled the hall the machine refused to perform. Reitsch figured the extra heat and humidity was the cause and ordered the massive double doors opened, leading to later claims that she had flown through the hall.
The audience, incidentally, had come for an exhibition of German triumphs and were bored rigid by this noisy machine going nowhere.
While we're cranking out useless information, I was amazed (being a Limey) when I found out that in the USA, if you're building a RotorWay, you can go to the factory, get 7.5hr dual training, then even if you have no other flying experience you can go home and hover your own machine until your teeth fall out - as long as you don't go anywhere. I think they may have lifted the minimum to 12 hours since I first found this out, but I pretend I don't know that and tell it the old way, sound better.
