Don't have a head but curious about the 'fly'. How is it turning out, final weight and flying characteristics? Got mine in hanger doing final assembly and rigging.

Flies excellent. Climb rate is pretty good, somewhere between 5-700'/min, which is surprising given just a 277, but then it is light. Weight is between 260 and 262, we are hoping to get an A&P friend to weigh it soon on his scales and sign off the papers that certify that it qualifies for part 103. We have a hand deployed parachute that weighs 9 pounds, so using the 25 pound leeway the FAA gives you for a parachute, it will "legally" weigh 246 pounds & qualify for Part 103.
Initially we had a lot of problems with vibration, have eliminated most of it, still trying to smooth it out some more. We replaced the rubber motor mounts with new ones ($ouch$) but can't tell any improvement in the vibration. Modified the muffler mounts once, will be modifying them again because we are still not completely satisfied with how they are working out. The muffler keeps wanting to hang crooked.
If anyone has an old Fisher style muffler that has the long straight expansion cone, and you want to sell it, let me know. Or even just the expansion cone.
Also be interested in buying one of those Balance Master mercury rings if someone has one of those for sale.
Next step will probably be to add a third blade to the Ivoprop, that ought to help the vibration some.
There is going to be a Fly-In at Greenville airport (GCY) this Saturday, we are planning to trailer it down there, put it together, fly it, and trailer it home, so that will be the first real test to see how well it does what we made it to do.
