You will have a hard time flying that plane with a 30 on a 4 blade. You will be disappointed in the lack of performance. I have the Hangar 9 P47 150. It is almost the same plane. I have a G62 on mine to swing a 4 blade and it fly's great. The G62 is twice the size of a 30. If you want to do a 4 blade go with at least a 50.
