- Total Flight Time
I would say that's all basically accurate, but I thought I would point out that I am 195 and my CFI was near 250 and we always managed fine in my Magni, with a full tank and just the 912 ULS. The 914 really only gives an extra 15 HP, and only for five minutes (of course at higher field altitudes the turbo will matter more).You can't even have an instructor like that with you in a GA 2 seat trainer airplane with full fuel. Most gyroplanes are designed to take 1232 pounds gross weight. Usually to have proper structure you can only achieve 45-55 split. That means useful load max in any light sport aircraft will be 45% of its gross weight. And that is the best one can get. Most of the time you only get a 40-60 split. In reality what you are asking your gyro to do is to lift its own weight or more in flight. That is a tall order. It can be done with composite structures and things like that but that increases the cost. Every pound extra costs $$$ in flying. There is no way around it. I at 145 pounds as an instructor on east side of the US can get away with an AR-1 with a 912ULS as even a trainer if I restrict my students to be 225 lbs or lower. But if I was also heavy I would have to pay $13k more to get at least a 914. All costs $$$
Last summer I took off with a guy who was more like 260, on a hot day. I took only a half tank of fuel and I decided to take off from the county airport, instead of my home turf runway, but again, no problem.
I will say it definitely helps to have the prop pitched to achieve near max RPM (5800) on takeoff. That means I can't go quite as fast in cruise anymore (risk of overspeed), but I'm happy to have that extra zip for takeoff, especially when near max gross (what would be really great is one of those DUC click-adjustable props, but I can't really justify that expense at the moment.)
