Thanks mrasmm - have some more info interspersed below - will attempt to get some pics up tonight.

yeah, it sounds like something is off, and it sounds like you are right in the trouble spot. The neg collective should be the same as the positive -12 or 13, and you said you are only getting 6. I would also make sure to use some 3 in 1 to lube the swash and the shaft and the main bearings, and work it out so you can get rid of that binding.

I adjusted the servo linkages on the swash 2 full turns (lowered the swash) so now it is more like 9/16" below the top of the main shaft. This eliminates "bottom out" with full negative collective. Adjusted pitch to now have -12/13 to +12/13 with 0 at midstick. This seems to be 2-3 degs too much, though and bogs down the motor at higher throttle. Now about -1/0 to +12/13 in normal mode. Pitch links are as short as I can get them so no way to remove anymore pitch in normal mode. Seems like this is still too much pitch with no way to adjust it further.

I have lubed the swash, but the binding on left/right cyclic is (seems to be) due to too much servo travel/limits of swash pivot. The mainshaft gets pushed (temporarily bent) to the left or right (maybe 1/16" at the top) with full left/right stick. Perhaps it was like this all along and I just never noticed. LHS seems to think so, but who knows.

Also check to make sure that your main pinion is not too tight or loose against the main gear. There should be some play, but not enough that it skips teeth or would rip them off.

I have tried several gear mesh settings and all have the same result. Right now it is as you suggest, a little bit of play but no chance of skipping teeth.

Guy at LHS suggested using a 10T due to the altitude here (~6200 ft). Bought one but haven't tried it yet. Still, it isn't performing nearly as well as before the rebuild.

Will get some pics up tonight and thanks again for the help.

you've probably already done that, but like you said, your problem is probably in your swash or head somewhere. My servo arms do not sit level either for the same reasons.

Go ahead and upload some of those pics, and we can look at it to see if we can see anything =)

oh yeah, and no prob here with the length of the post. I would much rather see a longer post with all of the info needed, than a 1 liner =)
