gnirwin,
I had a Sukhoi that had a HB .61 PDP motor in it. Can you say FAST. With a .61 in it, it makes a great pattern plane. It has a very high wing loading with the .61. It likes to be landed with a bit of speed. What motor are you planning on using? The Cowl is big enough to hide any .61 out there.
By the way I lost my first one to a engine failure, but i got another and will build it this winter.
