And others!!!
IVO seems to support the ultralight. The three blade they weigh in at 8 lbs while the medium would be 11 plus. Many have supported that view which is convincing. Leaves me with an unused medium hub but KF owners seem to all have such a collection. I guess that confirms we are experimental.

I will soon be ordering the 3 blade ultralight quick (ground) adjustable to comply with the LSA rules although I have been a private ASELS pilot since 1959. Keep the aircraft L S A.
