Just add a little oil to the ball, it will wear in very quickly. The tollerances are very tight onn the machine. If it is a problem I will obviously replac it.

i put some triflow on the ball and it loosend up a bit. im sure it will break in nice now. there is no slop in this swash! but i have noticed that the main gear has a little bit of up and down play on the auto sleeve. but other than that it spins freely and its not wobbly like my old t-rex!

The up and down play in the main gear is normal. That is a small amount of gap between the gears and the auto unit housing. Without that small gap it will all bind together. Most 50's and 90's are actually the same way.

yeah, I noticed the same thing, any tension at all and they get notchy, but you also have to realize they are thrust bearings, if you pull out and turn they smooth out, they will have a lot of centrifigal (spelling) force when flying. my theory anyway lol.
dont know how to prevent it you have to tighten them.
where are you in ga

If they feel notchy after the grips are assembled it is usually not the bearings, they are being preloaded by the dampers. If you glued the dampers in as suggested this is almost always the case. The tip is to make sure when you glue the dampers that you go all the way around them will a small screw driver or 1.5mm driver and make sure the dampers are flush with the edge of the head. If they stick out at all they will load the bearings and they will seem notchy after the head is assembled. An easy test is to mount the blades to the grips and pull outward on them and turn the grips. If the notchy feeling is reduced or goes away the dampers are sticking out of the head and need to be repositioned. If the bearings are notchy in the grips without being mounted send me an e-mail and I will send you a new set of bearings, as they should not be like that out of the box. Yes they can get damaged in a crash, but should be smooth out of the box before mounted.

I hope this makes sense, if not let me know and I will help in any way I can.

thanks for your reply. i mounted the blade grips the way you described glued the dampners flush with the headblock and i got one thats silky smooth and one that feels like it has sand in it. very notchy. took it appart and i have the same result, one silky smooth and one notchy bladegrip. just my luck eh? other than that everything else has been going together pretty good so far. i got the tail boom and tourqe tube installed and my servos.

long link 26.22mm
short link 12.64mm
swash height 10.21mm

my arms are set at perfect 90 deg. and that should put the washout arms flat with each other.

There should not be play, make sure everything it tight.
