I'm also considering the Seagull Edge 540 and did a ton of reading on here about it.. There is at least one guy who tried using Futaba 3004's and had them strip out on him.. I thought about using the kryptonite or whatever gears, but hear that they are finicky as well.. Probably just bite the bullet and buy a couple of Hitec HS625's.. Metal gears, and fast movement.. It would kill me to lose a plane because I cheaped out on servos!
