Hey RW,
Yeah, I know. I wish Randy had a little more info on his site. But Steve's designs come highly recommended. Like I say, Keith and fell in love with the line of the ship and may have some kits cut yet. In fact, I should get on the phone to Randy and order those plans tomorrow.
But in the mean time, the Legacy and Vector are both highly rated birds. Keith flies a Legacy with a Saito 56 and the nose shortened an inch to balance the heavier motor. Mike Pratt (he designed the Magnum for SIG) flew it and said that it was nearly perfect. Ditto on the Vector. I have a kit stashed away with a Stuka Stunt Works Magnum 36 for power.
My wife was kind enough to get me a Saito 56 for Christmas and I think the Herk might be a good home for it. I'll scratrch around for a picture. I can't recall seeing one lately.
I expect you could use the quik-fills, but nearly everyone I know, including some top drawer flyers, still use the old-fashioned syringe. I think it is a result of needing to watch fuel quantities carefully for flying the pattern. But for sport flying, it isn't critical.
