RE: Seagull Harmon Rocket
The gear works very nicely. I do have a recommendation, however. If you look at the gear, it has a taper down to the axle. Make the taper sweep to the rear, the straight edge of the gear to the rear, the sweep to the front, or the gear gets borderline too far forward. I can keep it straight on takeoff, but it takes a little work. Occasionally, once I get slowed down on the ground, it's tough to keep it from spinning out. I just have to reverse the sides on the gear, and remount the wheels so they point in the proper direction. That will move the axles back about 3/4" or so.
Mine flies nose heavy, or so it seems. There is no flair at touchdown, and landing speed is pretty quick. I even increased the throw on the elevator to 110% to try and get it to go a little more nose up before touchdown. Flaperons make this plane a little squirrely, maybe I am just spooking myself. I figured for a small homebuilt RV type, this should slow down more and land a little easier. It seems to go fast quite well, handles good at speed. I currently have the CG set at 3.5", maybe I will send it back a little more and see what happens.
