Cody, read the other H46 post and you will see that most everyone that already has the h46 will agree with you on the knife edge part. Mine will knife edge, but if you go past a certain point with the rudder, roll coupling suddenly takes over and rolls the airplane out of knife edge. After flying the H46 for a month, I've gotten better with flying it in knife edge but I don't think it will ever be great at it. The way the plane does everything else more than maked up for it, after all, it's called the Harrier 3D with stress on the 3D part. Mine balances at 140mm from the leading edge, I had to build a balance stand to accertain that as there is no way you can pick up the airplane by the covering at the wing roots to check the CG with any accuracy. With my balance stand I can be sure where the CG is at within less than mm. At that CG I wouldn't call it squirrely, just quick on high rated. On high rates I have the surfaces, including elevator, pretty much maxed out, and I can do a full elevator loop without the plane snapping. In low rates it flies pretty much like a sport plane. It does all the normal 3D manuevers, blenders, waterfalls, tic tocs and walls really good, and in a harrier it is solil as as a rock. Considering the only thing it doesn't do well is knife edge, I certainly wouldn't call it mediocre. You are right about the landing gear, it is much too soft. My son had the engine quit about five feet up in a landing with the nose up last Saturday (funny they won't continue running with the tank empty), it conpletly flattened the landing gear. Luckily, no other damage was sustained. We were at a fly-in flying over grass, if it had been over pavement there would probably have been some damage, including the valve covers on my Saito 82. I have found that the gear also twists backwards after a few landings, causing the tires to slide on take offs and landings. That wore the original tires out real fast. I made an aluminum 1/8 thick plate the width of the fusalage, bolted the gear to that with #6 stainless flat head screws and lock nuts and ran the gear mounting screws through both the gear and plate to mount the gear the the plane. That has stopped the gear from twisting backwards, but it is still to soft. With the backwards sweep that is built into the gear, I don't see any way to replace it.
Super D, mine also has the Saito 82. With that engine and a Tru Turn spinner and the reciever and 600 mill battery all the way at the rear of the radio conpartment, and using Futaba 9202 servos, it came out quite nose heavy. The original balance point was around 120mm from the leading edge. I never checked that with any accuracy, I made two marks at 140 and 150mm, transfered those to the bottom of the fusalage with a square, and set it on the balance stand. It balanced initially at least 20mm in front of the 140mm mark, maybe more. You may be happy flying the plane nose heavy, the only thing that really improved with moving the CG back was the walls.
All in all, I'm happy with the H46. After flying a Funtana 40 for a year with the same setup, I'd forgotten that an airplane could fly this good. The H46 does all the 3D manuevers at least as good as the Funtana, hovers and harriers a thousand percent better and isn't constantly on the edge of snapping, even in low rates. There may be other airplanes out there that fly better for other people, but so far I like my Harrier.
