Regarding the engine, that is a very personal decision and varies a lot based upon flying style. For example, a G38 will fly it fine, but is not enough power for my tastes. I have a FPE 40cc in mine. I think at least a 50cc engine would be better, especially if you like flying long climbing turns. As others have said, extra engine weight is no problem. If I was doing it again, I would look at a 60cc engine, such as the 3W60 or something similar.

I shall want to fly the model in a mostly scale manner with 'scale looking speeds'. So I was thinking the smaller ZDZ40 so I didnt have to throttle back so much and just be putt, putting around at a really low RPM. I dont want it to be able to climb out of sight, just have some positive climb with energy management. I think you would be able to get some real spectacular fast passes with a 60cc but how long will the airframe last? It was designed to fly on a ST3000 and although a 2 stroke this is way less.
Those of you with a 50cc do you have to throttle back to just over idle for scale type level flight?
