The biggest challenge will be finding someone to launch it open exhaust..
If I don't like the way it throttles, I'd be tempted to have Jett make a replacement with a suitable bore size. The carb I put on the OPS .65 works like a charm so far. And it would look kewl.
Oh, for those in line for short kits, all the wood parts and all the spars are cut. I need to pick up a case of mailing tubes and get some plans printed (I have some but too much humidity cycling, they're headed for the wood stove), then we're good to go. Sorry I'm a bit slow guys but we're just about there.
