RE: 73" yak evolution 26gt
No tuned pipe guys. Quique flew the 73" and he said it was very good power for IMAC and enough power for any 3D. He said performance was great for a small gas engine but not as good as glow like YS 1.40. Pull out of hovers were kind of slow. Weight 11.5 lbs. No videos yet but next time he gets to fly it, there will be videos.
Thank you,
