Hello, Arthur from Norway here...
I have bought a Butterfly Monarch with the 582 Rotax. Do you think its possible to fit a Yamaha like yours in that machine?
Larry Neil said that about 5000 densety altitude was all I could expect from it as is, and the mountains I will fly in is pretty much 4-6000 her in Norway. Limits my flying window.
Is this something you could help me with in the future, possably next year? I bought the gyro in MI and shippes it to me via SLC Utah. I have some Ski-doos sleds that are shipping to me and some friens, and I have spare place for the gyro.
Larry uses the Rotax 912 ULS in the Morarch, about the same output as your setup, but 4X the cash...
Thannks in advance.
Arthur Oysaed
