What can you do with it Bug, apart from a sneaky hover ?

I'm guessing it doesn't have a permit ?

Other nations are awash with 'experimentals'..but they're useless over here in Blighty

PD

Does anyone have that big balls?

I'd have a go at hovering it but i'd prefer it to have a collective. :ok:

All i need now is the balls
 

The end of the collective is just visible next to the lower part of the cyclic. It is a white disc with a flat on it. Bug .

Bug... that :confused:

Wheels?
 

Surely you can just pick it up...

Don't forget the Fedora and overcoat when experimenting with new types.

What are the wheels on rear boom? Please don't tell me its a belt drive to rear fan
I presume the vertical case is a cover for the drive either chain or belt to a X shaft & then a bevel to the top fanny thing and the tail drive is off the X shaft. I presume that is the reason for the steeped pulley in centre of boom.
I have Small .. so will be of no use whatsoever :E please keep me informed as to your continued health, as my granny said to each his own looks well put together though

it's budget homebuilt.
No need for angled gearboxes :-)
Belt would do. And you get get replacement in homebase..

size counts
 

More substantial seatbelt than the Robbies. Be careful. Small choppers remind me of toy dogs, they can have a nasty bite disproportionate to their statue.

I'm not sure the multiple failure points on the tailboom are necessary - way too complicated!

I think the size of the carton of juice at the top is disproportionate to the size of the machine.

Mitigate the problems that you might feel would arise, wear some good bodyarmour and connect the battery, I think I would have a go but what really puts me off is all those drive belts to the T/r , wind blown leaves would cause those belts to come adrift, they look flat would be better if Vees. and short belt connection to drive a lightweight shaft thru a small G/Box

Get some body to Vid it when your trying, Oh and what about tethering it to a couple of tractors, very interesting! Good luck!:eek:

Same machine, but with a different M/R head? Love the BERP blades and skateboards for ground handling:

after watching that video, just a couple of points!

1. are those flat belts driving the tail rotor?:eek:

2. Is this just a wind up?:confused:

3. I've changed my mind!;)

"Trying it"
 

You could call up the Pilots Office at Westland, and I am sure someone would be glad to give you advice on how to proceed.

Thanks,

I don't know what frightens me more - the cheap, supermarket-style, plastic fuel container, that obviously has passed muster as a fuel tank (please tell me, it's fuel-rated plastic) - or the frightening multiple-belt tail rotor drive system that reminds one of a flat-belt-powered machine shop, of pre-WW1 vintage.

I reckon the life of the whole unit, including the operator (I wouldn't dare call him a pilot - a circus daredevil, would be a more fitting term) revolves around the life of the plastic fuel container - which I would estimate at 3 weeks maximum - and possibly even considerably less, if subjected to strong UV light ..... :eek:

For those of a more technical nature. The small blades in the video clip were only to put a little drag on the drive system whilst testing the tail rotor. The tail drive system was run for several hours at on and a half times its normal running speed. The vee and toothed belts have given no problems to date. Belts provided a lighter method of transmitting power to the tail, negating the need for an anglebox on the boom,helping with the longtitudinal balance. As i have some 80 hp available the extra drag of the belts is not a promblem. The small fuel tank ensures only short runs are possible during testing. Each run is followed by a full inspection of all critical components.The tailboom is extendable via a carbon sleeve, this allows all belts to be tensioned at one go.

I like the belts. Should work fine as long as they don't come off the wheels.

Looks cool!


p.s. Hope you have some recent piloting time or dual instruction.
