I've owned both the FuntanaX50 and a Fliton Edge 540 (same size and weight as the Extra). I hated the Funtana. I put so much work into getting it to fly right...balance, throws, servo position, servo linkage, etc. It never knife-edged worth a crap, hover was awful, harriers rocked like crazy. The only three decent things it did were snap-rolls/blenders, INVERTED flat spins, INVERTED harriers. I grouped snap rolls and blenders together b/c they're essentially the same thing. Inverted harriers are decent, if you're towards the end of your tank and have a nice head-wind. The Flat Spins are always good. Also, you really can't fly it with much wind.

I only flew the edge 8 times before the Rx battery came undone and allowed the plane to land, full throttle and spinner first (destroyed my brand new Saito 100). Needless to say, the edge was still nose-heavy for 3D flying. The edge knife-edged like a dream, harriered like it had gyro's on it, flat spins were flat and tight, spins were tight, snap rolls were deep and crisp and stopped when you wanted them to. My maiden flight was in 15 knots of wind. Didn't phase me or the plane, which flew like it was on rails even in the wind. Lomcevaks were great, and it even taught me how to do a rolling-harrier and a rolling circle.

Yeah, the Fliton Edge isn't the Extra...but the Extra weighs 2oz more and has about 200 sq in more wing area. So, maybe the Fliton is a bit more expensive. It may also require more money for the engine and servos, but that's besides the point. I'd rather have one plane that flies like the Fliton than 5 planes that fly like the Funtana. Get a Futaba S3010 on the rudder, set it up with dual elevator servos in the tail, and a Saito 100 spinning an APC 16x4W. Once you fly that plane, you'll be addicted.
