I am still debating using an OS FS 120 because I have one but I wanted to get into gas. Now that I am looking at the kit I know installing the 120 would be a lot easier, however I still am itchung to go gas. It is hard to compare the output between glow and gas. For instance the MVVS 26cc says it has 3.8HP or 2,8KW @ 9000 RPM. Now that definatley sounds like more output than the Zenoah G26 or the OS FS 120. Can you just look at these figures and go by the numbers or is there something else to look at. I don't want to put too much power in the Stearman, but I have too many planes that I wish I had bought bigger engines for and I don't want to make that mistake again. Sorry I am rambling, I guess I just want to make sure that the MVVS 26cc actually has quit a bit more power than the OS fS 120.
Thanks
