I am one of the top guys on the waiting list and can't wait to get it!
In my opinion (from what I've seen and heard) is that the smaller MW-54, RAM 500 and a MW44 would be a perfect match for this bird. It is one sleek looking small bird and installing a bigger engine like P-80 would spoil its looks. I doubt we'll be able to go to max throttle with a 17lb thrust engine anyway. I know we can detune the engine but another consideration would be residual thrust! With a sleek, slippery design like that, its not going to want to come down slow.
If I can find a MW-54, RAM 500 at a good price and a reliable running state, I'll get one but untill then, I'm planning on using my trusty GWM FD 3/67 engine on it. The looks will spoil a bit but Landing should be a no-brainer!
