250lb pilot

[mylinn700@comms]

I would like to know if a Dominator can practicably be set up to haul a 250 lb. pilot and operate at seven or eight thousand feet. Thanks for any information----Ron

Yes, Ron, providing a large enough rotor and a large enough engine. I would say a 25 ft DW rotor and a 100 HP Rotax would be perfect for you. A Rotax 582 will also pull you off the ground but you will be miserable during high DA days. Some auto conversions, like a Soob 2.2, would also work fine but they will make the gyro even heavier. If you can afford it, go for the 912.

My Dominator with 25 ft Dragon Wings and a 65HP Hirth, fuel injected, computer controlled, flys just fine with lots to spare at 8000 ft DA. I weigh 205 and I have extra weight on the Dominator. Radio, heavy battery, ect! It climbs at about 700 fpm (on the EIS variometer) so it should work very well for you.

Ron, is this 8,000 feet above sea level or is this 8,000 feet density altitude? Chances are you may perform a bit better with 27ft Dragon Wings. It is possible to fly provided you have enough power. Some rough figures I considered here in Colorado:

1. Stay less than 10 lbs. per HP (talking gross flying weight here, 8 lbs is better).
2. Disk loading (the gross weight distributed over the disk area) should probably be around 1.2 to 1.3 lbs per sq/ft.

8000 would be above sea level.I think density altitude could easily exceed 10000 feet around here in the summer. I
live in a small valley at about 3100 ft,but would need 6000 ft sea level just to get out. I'm sure it would be early morning flying in the summer. Thanks for the info. It will be very useful. Ron
