Ok you guys a confussing the crap out of me. My question was with regards to the ability of the .91 4 stoke motor I have already purchased to provide adequit power to the two planes listed. I have past experience with flying and have been through a 40 size trainer and also a40 size low wing sport plane. I am getting back into it and have flown the crap out of the 55" trainer I currently have. SkyPilot seems to think that the .91 4 stoke will be fine in the Edgs 540 60 and the Pheonix 330s whereas others say that at least the egde 540 60(68" wing)would be moderatly if not severaly under powered with that engine.. The hanger-9 pulse 60 is bigger, heavier, and more expensive than the two planes I was asking about??? I do not want to go the 4-Star 60 route as that is a kit and I am interested in ARF's. Does anyone have any thoughts on the Seagull egde 540 46 model. This is a 60" wiing span and suggests a .60 to a .80 4stroke. Would the .91 4 stroke be too much for it. It is a 6.5 to 7 lb planes. As of yesterday I saw a video of the Pheonix 330s a 7 lb plane 64" wing span with the very engine I have in it (Magnum .91 4stroke) and it seemed to fly very nicely. May not do unlimited vertical climb or even hover for a long time but it did hover for abit and these planes seem to glide forever... sometimes hard to get them down as they want to glide right through the runway!! That plane (ARF) can be had for $125.00 right now.
