The big moki is more than you need but will be a lot of fun.A friend of mine is using one in his H9 cap and is way more than he needs.I,m using a OS 160 in my edge and it is plenty for the plane for hovering and is pretty good on fuel.I own some saitos but they don,t put out the power like my big 2 cycles and they suck fuel so i use them in scale planes for the sound.The mokis are powerful but they like a lot of fuel so i would only use one in a plane that can use that much power.The 160 would be a good choice for this plane but thats just my view.
