Moki vs OS
The Moki 210 ia a bunch of motor for that plane but it would never be any where under powered. I had an OS 160 swing a Pro Zinger 18/6 and the poer to weight was damn good but there were a few times I wished for more power. The Moki 210 is a real beast and would be an fantasic combo but the Moki is pretty hard on the fuel consuption but there is plenty room in the tank compartment for a larger tank.
