Having only just noticed onetrack,s concern over the fuel tank. Rest assured cobber, it,or rather they, are indeed designed to carry petrolium spirit. I note too your observations as to the pilot,clown,nutter, or whatever other noun you choose to describe yours truly. Permit me to say this is the uk mate. we breed em tough and fearless here. wich is why i shall resist giving you a tongue lashing on this occasion. Peace to all men, and a safe 2010

Good on you Bug!
Bug,
whether the MK4 ever flies or remains an engineering passion for you, I wish you every success.
The world needs more people like you -- you cheer us all up. Well me, anyway.
And I'd rather be in your machine than in that weird Japanese 4-engines-just above-your-head-thing that we've seen here in previous posts.
Having said that, I think both yours and the Japanese one look great fun -- and there's an American one to check out as well -- the Air Scooter. (I don't know how to add the links).
Happy landings!

Quite simply brilliant. Go for it!
Youth passes - but with luck immaturity will last a life time!
Good luck and best wishes for a simply exciting new year - keep us all posted

Seriously, anything you can adjust the c of g of, just to tension the belts? You serious?
You say the belts have been tested up to higher speeds, how about increased loading due thrust from the tail?
Good luck for 2010. I'm all for homebuilds, exciting stuff but I don't think it'll ever fly.
If it does, please post the vid up here to prove us naysayers all wrong.

The tail fenestron, blades and sliding guide tube are carbon, the shafts are titanium. The digree of movement to tension the belts has minimal effect on the c of g which remains within limits with up to two inches of tail movement. The belts, blades,and linkages have undergone several hours of full load and movement. to date no problems. I thank you all for your replies, and of course will post a vidio when i have succesfully flown the machine. May i quote Otto Lilienthal It is easy to invent a flying machine, more difficult to build one, to make it fly is everything

Looking at the "collective" I am assuming it is a fixed pitch heli? And your knob that you call the collective is a throttle perhaps?
If that is true then good luck, my model helis were a pain to fly as a fixed pitch machine, there was a noticable delay between inputting power and the aircraft gaining altitude. The normal point for noticing this is when descending too fast and needing to stop the descent and praying it reacts in time.
I'm being anal here but you don't have a Fenestron, a fenstron is what is on a dauphan/ec155 etc, the tail blades enclosed in the tail fuselage. You have a normal tail rotor but I don't know if it has a specific name.
Good luck and be carefull, but we want a video of the outcome good OR bad.

The Vid of the run up must be the LHD export model, is that why the belts are on the port side?
Still like it, but with a few reservations

So it looks as if the Rotorheads are pretty much in agreement, as we all seem to like the 'idea' but I have to say, the more I think about it, I feel that Bug is running 3 cans short of a six pack!
I'm looking forward to the flying video. Bit like 'A Chopper is Born'!

Bug,
I have nothing but good wishes for your adventure. To build something like this takes a lot of nouse and I tips me hat to you.
Good luck and take it slow (and low).

Homebuilt Ultralight G-1 Helicopter
And heres one where the plans are 24.95 or 2 for 26.95 , but if you act now we will throw in the graty as well
Also note that they will pay for any flight video

I thought i had sort of signed off on this topic, but cant resist. In answer to points raised. Firstly "fenestron" stand orrected on that one. perhaps its impenage or something similar. Second. tail rotor is driven vai pulleys both sides of the boom which are not interconnected. The system will drive on one,or both sides. Any lateral flex in the tailboom is restricted by the belt on the .side that would tend to lengthen. The machine has a conventional collective lever with a twistgrip throttle. It has built in correlation,that can be overidden where necessary. Bug. ps i have a question for more knowledgeable folk than myself. Is it safer to tether the machine for initial lift off, and risk the snatching about at around twelve inches off the floor. or should i go for the full monty,and just grit my teeth.
