Just seen that second pic in Heli Life this month - says they have 4, 2stroke engines, and if one fails the others allow you to fly (I imagine it means land safely!)
I havn't been able to work out how Yaw is achieved on it though???

Another photo, and a bit of an explanation this time...

I was just wondering what this machine is like for a jolly, compared to say an R22 as a personal helicopter? Does it have any terrible traits (other than the ones every other helicopter suffers from)?

Nice one!
Bug,
Looks like you have been busy!
Try not to take too much notice of the nay-sayers, why don't you tell us a little about it?
What engine does it use?
What does the feature on top of the hub do?
What performance does it have?
What are you going to do with it next?
Looking forward to your reply!
CRAN

Looks like a lot of dedication has gone into that little machine, BugDevHeli!
What powertrain does it use, or was it all developed for that machine? Looks like R22 MR G/box. Lot of development...

I'd like to hear more about it!
Was thinking at work today ... how would one go about type conversion to a single seater???!! What do the CAA say about the logistics of adding one to a PPL(H) licence?

whats this then.
crangravyslorotorcraig. Thanks for the less urine extracting fedback. The machine has a total auw of 500lbs a 20 ft rotor span and is powered by a BMW 750cc watercooled engine. Rotor blades are shortened 22 with a carbon kevlar composite root. Tail rotor, carbon fibre. Tail rotor driven via conventional drive shaft to tail gearbox. cyclic and collective via push pull cables with a device that permits the phase lag to be manually adjusted during testing. Power is transmitted via 5 vee belts, the engine being pivoted at its rear end and is pushed down by a motor and worm gear to tension the belts.. skid gear is a mixture of carbon and alloy. The screens are blown in polycarbonate. The little device propped on top of the rotor is a 5 foot model of my patented ring rotor system. This rotor system provides very high inertia without the necessity for a huge hub whilst at the same time reduces tip losses to a minimum due to its blade ring tiplets. Bug 3 is currently being tested ground tethered to prove as far as is possible any weaknesses in any critical components. Once this testing programme is completed a full sized ring rotor, which is under construction will be fitted ,and the necessary testing to verify that the fluid dynamic analysis that has been carried out on the ring rotor,works as the test results would suggest, I may then be somewhere near the goal of producing a vlh machine that is reasonably safe .

I didn't realise it was April 1st.
It is only a simulator, right? 
So why is a part of it for sale on Ebay then?

In reply to kiss my squirrel. 1. The machine on the pprune post is a complete homebuilt helicopter. the advert on ebay is meant to asses the likely market for a simulator that looks very similar to the one you see on prune. So as not to offend ebay by simply using there service as an advertising means, i have offered for sale (as the advert clearly states) a fibre glass body. 2, As it is approaching the festive season i thought it might raise a few serious queries as to what the object was on top of the rotor shaft. WRONG AGAIN ,oh well, perhaps this explanation clears it all up. or maybe!!!
