I have used Fiberglass Specialties before and exchanged a couple of emails with them today. I bought the Sig 25% Spacewalker cowl which pretty much matches up with the Seagull Spacewalker with a few minor adjustments. I have an Evolution 26 gas engine in mine, the engine comes from MVVS and was offered by Horizon Hobbby. They no longer carry it but it is one great engine. I am thinking of buying the Evolution 40cc from one of my flying buddies. It is also an MVVS engine and I think Horizon still carries them. I have a plane in mind for it.

Thanks,
