Rob, you're funny. I think Sheepdog calculated like 50" long or something!
Craig, I might make some of the engineers and machinists here crazy, but I work in "about" rather than in .000001s. I removed the spacers that went with the 5" wheels to keep each "set" the same, and I used 1/4" spacer and a machine shim (about 14ga) on the inside of the hub, and a 1/2" spacer on the outside. Because my axles and axle nuts are not drilled equally, on one side I had to use another machine shim to find a happy place for inserting the cotter pin through the nut.
Dave, my right main has a bit of hop that feels like a balance issue between 29mph and 34 mph. It is not noticeably present before or after those speeds. I'll pull each back off and actually try balance them, trying to move the tire's location relative to valve stem rather than using weights if at all possible. I'm not sure if it will fit on my spin balancer, but if not I'll try to static balance it.
While it was a little disconcerting at first (in fact, I did some "medium" speed taxiing around and the first time I felt it I stopped, shut down, got out, and reinspected EVERYTHING) I did end up doing a couple of full stop landings and nothing felt unsafe or unpredictable--just a little annoying, but I'm sure it can be corrected.
I fly out of Greeley, work in Lafayette, so if you want to take a closer look sometime, you're welcome. I'm heading out of the country for the next month though, so I'm really happy I got to fly and check 'em out before I leave!
I also noticed that my left main rotor was noticeably hotter than the right side after taxiing, and when I lifted the tail, it wanted to go left. My suspicion is that brake is rubbing just a little bit, so I'll take a closer look at that as well. I wasn't getting too worked up about anything as the rotors had a less than impressive finish on them upon arrival, and I figured I'd let the brake pads create their own surface anyway.
In all, I was really pleased, and it was pretty cool to see a bunch of guys at an otherwise quiet airport stop what they were doing and look up as I taxied by. I got one thumbs up, and I'm pretty sure a couple, "WHAT THE ****s" as I went by.
