I hoped you beefed up the firewall on your Subaru with that .72 Saito on it. I have the .52 Magnum 4stroke on my Subaru, and it was more than the firewall could handle, and that .72 gots tons more power than my .52. I had to remove the engine, and add some tri stock back behind, plus a good heapin helpin of good 30 minute epoxy which was definately missing in my Subaru. Just a couple little spots of glue holding the firewall on originally, but she good and strong now. Also had to touch up all visable joints within view inside the fuse with some CA. Don't wanna think much about the places I can't see or reach. After this said though, I do enjoy flying the Plane and I like the way it handles. A person just wants to do a real good inspection while assembling would be my recommendation. As a matter of fact I would not recommend that anyone should purchase this Plane. There are much better quallity brands for the same money. All I am saying is that since I allready own one, and have doctored it to make it as flight worthy as possible, it is a fun Plane to fly, and really looks good in the air. I would put my money somewhere else though if I had to go back and make the decision again.
