From what I've read elsewhere it seems that the ignition on the 202 could be a weak link if not dealt with very carefully. Comments?

All,

I am still somewhat interested in building an Ultralight Butterfly. Who has built one and or is currently flying one? I weigh over 230 pounds and am curious about the MZ202 performance. My goal is to build hours and work toward becoming a Sport Pilot CFI. Plus, I want to have the experience of building a Gyro.

Tom, contact Mike Burton at Airgyro in Utah. He just did the first test flight of an MZ-202-powered Butterfly Ultralight for a member of our chapter, and it had plenty of power, even at 4500' MSL.

Butterfly specifies, but no longer serves as a distributor for the MZ-202. It may have something to do with the fact our local builder had to wait months for the last few parts of the engine to be delivered. But there is a used one available with fresh overhaul for a good price right now in our neck of the woods, should you want to go that route.

Tom,

I believe Ron Clifton with with the Lone Star Rotorcraft Club near Houston has an ultralight butterfly with the MZ202. He has it built, but I'm not sure if he's flying it yet. The last report I heard he was dealing with some wiring issues.

Thanks Paul, I am emailing back and forth with Thomas. I did not ask him, but, why is he selling it?

Larry sold 9 UL's total of which 3 are MZ 202's.

He said he'd use the MZ202 on the Monarch as well when the 582 goes by by. He believes it may be around for a while yet though.

Greg,

I am looking at building an Emperor Butterfly using the MZ 202. I have a PM that suggests using 2.88 reduction drive with a 70" plus 2 blade prop, which gives 360 pounds of thrust. However, I am afraid that the Emperor will only accommodate a 60" prop, so it might need 3 blades.

Finally, there is a used MZ 202 with a 2.55 reduction drive. Perhaps someone can tell me if the 2.55 would be adequate for the Emperor.

I have decided on more horsepower, due to my weight.

Hi, I am in need of some help sourcing the final parts for the Ultralight Butterfly. Larry Neal died before I received the last of the Kit and I'm not getting any response from the company. Specifically I need the MZ202 engine, prop, reduction gear parts and muffler.

any help would be appreciated,

Thanks
