The request for the Yak 55 wasn't for a 3D plane, but for IMAC mostly, everyone who has see and flown the Comp-ARF 3.3 meter knows how sweet it is. The problem with it is the price and the need of a $2000 engine to power it. You cannot compare the Yak-55 to the YaK-54 they are different in many ways. Plus if anyone is sick of something, I'm sick of hearing people saying they are YAKed out. Until you have flown a YAK 55 you can't even comment on it. Another reason I brought this up was because I wanted Tom to know many comments have been made by IMAC guys saying they wished there was a YAK 55 out there for a DA150 size that didn't cost a arm and legg. Oh and if you want a 40% 540 start your own thread, I'm Edged out LOL
