In Montelimar there was a small company called Helitech, they had fitted a mosquito with an artic cat with a double injection/double ignition

the engine was crazy powerful .... nothing to see with a rotax as a matter of fact



this is my airstrip, and my hangar, I am flying there !

they were designing a second version with a double twin 2 stroke engine (2 half engines connected to a free wheel) ...

but the boss died on a LH212 with a trainee on board and the company closed it's doors

one of the anti torque rotor blade broke ...

I love it!
Sweet little helicopter.
I'd love to own one!

The Arctic cat 800 is a monster!
Barry Thigpen put one on his ultralight phantom and the thing takes off and climbs like a rocket.

to make a long story short, I build not one but 2 tandems, at least the parts of two tandem

Invested 9000 euros in an artic cat project in association with a guy who was suppose to build a dyno, and convert an engine, the deal was that I would make a gyro for me and on for him , pay the engines and proove the world he would be able to do this and then sell engines..

it lasted for years , he only sent me pictures of the engines and an evaluation of the thousand extra euros to finish the job ...

I stopped this ..

and as far as I know except speaking of engine on the forum he did nothing

I don't mind I make a descent living and I can afford loosing money ... but it pooves that appart from mounting an running engine with it's original component on the gyro , it is impossible without deep knoledge to implement a custom injection/ignition system on an engine block

conversions must remain simple stupid

and obviouly it works

I used to watch some guys on a farm move 44 gallon drums of fuel around with schweitzer 300 or hughes 269... (I can't tell the difference) helicopters... they would knock the barrel over, then roll it to where they wanted it, then stand it up again... then set down next to it and fill up... then roll it back to their hanger

In that vid with the bottles... can a R44 hover as long as it likes without doing a short flight? I guess they have a transmission overheat warning? I know some of the big rescue type helis have to do a short go around (even have a go-a-round button to do it automatically) ... evidently they can only hover for like 3 minutes without a go around? Hillbilly... do you know?

They are the same oh and TH55 LOL

Unless your over gross or out in the African Sahara in the middle of summer, it's hard to over temp a gear box

Doing long line work your in a hover out of ground effect and we never had issues... DA was the lift limiting factor

Hughes 269 had several models

269 pilot right seat fuel tank left side manual clutch with a small buzz saw for a tail rotor, small instrument panel
269 A pilot left seat, electric clutch fuel tank right side bigger tail rotor Small instrument panel
269 B Same with an up rated engine, big instrument panel' better tail fin
269 C Same with a bench seat better tail fin

TH 55 An A model with ugly seats and electric clutch

Early helicopters like the flying banana had issues with heat, Early S 55s had a short TBO with its main gear boxes
