I was looking thru some of my old stuff and found a video of the time we were doing certification Fatigue flight testing on the Exec 90. No big deal stuff - some might be interested in the strain gauges and computer (big time back in the earliy ninties!).

I'll do a dial up wmv file later - in the meantime you will need either a broadband connection or 56K patience as it's 10 Mb.

That was the best Rotorway flight Video i have seen yet, who was the Pilot? he really put it through it's paces, also what engine was in that one?
at one point the pilot climbed stright up, how high did he get before he transitioned? reason I ask, is I am building a Scorpion with a 162 carb. exec engine,I hope to be able to fly out of the back yard with it once I have it proven and I get good enough to feel safe doing it. I would have to clear 30 foot trees on takeoff. I would be able to run about 200 feet to clear them. but it looks like I could probably do a vertical takeoff to about 40 feet and transition as i am climbing out,just would hope the engine did not burp.
Do you know if anyone has done stress tests on the Vortech/fleck rotorblades?
I have Vortechs now but may try and find some good used 269 hughes blades.
any info you have on the Rotorways and different blades would be great.

that Video sure made my night, i had just come in from working on mine,and footage like that sure inspires me to keep working.
Fly Safe.

Fly Safe.

It was a standard Exec 90 150 Hp engine. The vertical was just because we were having calculated fun - and - I don't normally reccomend or do this for normal daily ops except as necessary due the probability of Low RPM Rotor Blade stall due lack of blade energy if the engine quits . In other words - play safe and use your 200ft for a normal transition and max power/performance take off. With 200ft you can always do a climbing circular take off if the wind is OK. Your flight manual Height velocity diagram is actually an energy image. It tells you where you don't have enough stored energy to make a safe landing sans engine power. Talk to me privately if I can help in any way.

Can't help with other info

safe flying and enjoy your project
