Just got my Edge ARF into the air over the last few days. Awesome! I am using the OS .91FX with a Bisson pitts muffler.
My plane came out very light compared to what I have heard other people saying theirs weighs. 7lbs 15 oz RTF minus fuel.
The .91 pulls is around very well at this weight. TR's and hovers are comfortable at half throttle. Pull outs aren't fast but enough to make it easy. Only things I changed on the kit were replace the metal hinges, put the elev servos in the tail and run the rudder on a pull pull system. It does the coolest walls and parachutes! Needless to say, I really like this plane.
