From what I have heard the Satio 100 is a solid engine. I'm going to use a Saito 125. The guy I bought the CMP Hellcat from has been building planes for over 35 year. He bought it to build for someone but the customer back out at the last minute. Some of the planes he has done are starch built from pictures. I have seen his work at his house and this guy is the real deal. My point is he told me you wouldn't need anything larger than a 91 (4) stroke in this plane.

The guy that trained me and who builds also; and has been flying since he was 14 (he’s 56 now) said to me...These war planes that we are flying are really just sport planes but do have certain tendencies of war planes. Both these guys told me if you over power a war plane they become less controllable. I'm not an expert but I do a lot of research before a build a plane too. I also know a guy that has a Hanger 9 Hellcat it’s a little smaller but he uses a Saito 91 and it flies like a bat out of hell.

So with all that being said I like the Saito 125 because it’s light and powerful but I think a 100 4 stroke would also be okay. Depends on what kind of flying you can handle and of course what kind of flying you want to do. I know a lot of people say the bigger the better but that’s always true when it come to engines, weight is an issue.

Another thought is to look at the dimensions of the 100 and compare them to the 125. I haven’t looked but I think they are close in size. Try the 100 and if you feel it isn’t enough for you then could go to the 125. What ever you decide just remember to keep this plane as light as possible.
Good luck and Happy Flying.
