Helo Jordan:

You and I are in the same boat. I am scratch building the same size Ultimate Bipe. 63 inch wing span.

Mine is a scaled up Goldberg Ultimate kit. For a cowl I am using an Ohio RC 62 inch fiberglass cowl.

I will be using a Moki 180 on mine. Cost of no nitro fuel is $9 per gallon, not as cheap as gas but I can live with this price.

I have my bottom wing framed up and will start on the fuse this weekend. Hope to fly it around April.

I have not sourced a canopy yet. Do you have any ideas?

Zimpro marketing makes a ARF Ultimate, 62 inch wing span. They recomended the Moki 180
