Hi folks,
Thanks for the add. I have not yet flown a gyro. I have a half dozen hours of flight instruction logged for my fixed wing sport pilot certificate. After that I’ll get gyro CFI training.

In the meantime I picked up a Butterfly Ultralight gyro frame. Previous owner flew it regularly but passed away and while his home was vacant it was broken into and the rotor, engine, prop, and electronics and cables were stripped off the frame. The estate sold it to me for $500. I have a 582 with B gearbox and 2.58 gears, a 64” Powerfin B 3 blade prop, an older 24’ Rotordyne rotor, and a tall tail for it. I plan to widen the main landing gear a bit too. I’m restoring the original electric prerotator that supposedly will spin up the rotor to 220rrpm.

Can anyone comment on this particular make and model? It was originally part 103 compliant but with my changes it will likely be a good bit more than that.

I’m a big guy, 6’2” and 275 lbs and live 800’ above sea level in northwest Virginia’s Shenandoah Valley.

Is this combination of motor, prop and rotor sufficient to get my fat a$$ up in the air lol?

Try PM ing Dropbear - Others here too.

I'm a helicopter guy but the weights and power seem good = Average numbers

800 ft above sea level is good too.

Ken Brocks freedom flyin was in the El Mirage dry lake - had all types there

Welcome

Keep it light. At your weight you cannot put any extra weight on the gyro.
My old dominator weighed 330 lbs. rotax 582 60 in prop, my weight 175. 23ft rotors.

The 24ft rotordynes will make good lift but not a lot of speed . you should be fine just don't add lots of extra stuff to the gyro, keep it light.

Great, thanks. With my size and while I’m learning I think I need the lift much more than I need speed, and I’m told these “float” better while landing and are more forgiving in general than the more modern / aggressive rotors. My goal is just to cruise and sightsee, not high speed. In the future I can upgrade to a more modern rotor.

Usually on a small gyro if you are "hindered by weight" the larger blades can compensate up to a point by providing more lift.
There are charts and graphs and spreadsheets to calculate weight/rotor size rotor Rpm etc. Dragon wings do not like to turn slow they must be kept in a certain rpm range, other rotors are more forgiving.
you will learn all this as you dig in.

Be sure that it has the newer design front-wheel U-shaped fork not the original one-arm L-shaped front-wheel" fork" - that broke on several Butterfly UL's and balled up several machines!
