reprice19: the seagull edge 540 balance came out almost perfect with the os 91fx. i have a 1400 mah battery pack up behind the firewall as the book shows and have standard servos in the tail and wing with the rudder being a futaba 3010. did not use the carbon fiber pushrods. first time seeing them and i could not just trust them with super glue yet till i learn a little more about them. did change the tail wheel to a sullivan type. also i had a little engine overheating problem at first. i did not cut the cowl at the bottom back where it
shows a half moon shape across the muffler. also installed a great planes fueling valve and did not use the extra tube from the fuel tank. blocked it off. also you need to cut the cowl so you can get your finger on the muffler pressure line fitting when cutting out for the muffler. makes it easier to get it on and off. i also blocked the right side of the cowl opening with a piece of thin plywood so all the air would go over the engine head. run the engine a little on the rich side. i have not had any more overheating problems. you will need a starter to start the engine the first time.
running an apc 15x4 prop. it really pulls the plane around. flies real well. have not tried much 3d yet. i had this engine on a sig mayhem
which was not quite enough for me. i put a new os 120 ax on the mayhem and now it goes vertical from a hover like it was shot out of a cannon. the engine mount may be alright but is has a hole down the center of each rail. like i said when i drilled it i saw this hole because the drill dropped through it and that is the way i knew it was there. when i first put the starter on the spinner i noticed it bounced around. the second time it moved all over the place. i stopped and looked at the firewall thinking it was loose but it was fine. i then pulled the prop back and forth in the direction it is mounted. it would probaly move at least quarter inch in either direction. replaced it with a great planes adjustable mount. no more movement. all mounting bolts were tight and loctited. the wheel pants are a little flimsy. could be better. i would try it first with standard landing gear and a nicad battery pack and the lite wheels that came with the kit. i think you will be satisfied with the setup. if do not have an os 91fx yet i would get the os120 ax. towerhobbies has it for about
$40 more than the 91fx and what a difference it makes just have to hold the throtte back. the 91 fx will take it vertical out of sight. this is my son's plane. we were flying the 46 nad 60 size ucandos but mine went in from a complete radio failure. he had the 46 size but after flying the 540 he likes it a lot better. we satisfied with the 540 so far except for the mount and wheel pants.
