I was curious if anyone is currently using the Saito 150 Golden Knight AAC:GG engine in a Showtime 4-D 90 plane. Trying to find out about performance, mounting issues, CG issues, and last but not least, firewall / airframe structure re-enforcement needs. I've pretty much ruled out using the Saito 100. I have heard the 125 Saito is pretty good (power wise). Deff. gonna go with a Saito...but trying to make my 1st engine for the plane the right one. Any info or tips would be greatly appreciated. Thanks!
