450 Pro swash ball tightness
Hello,

I just picked up a 2nd hand pro and was wondering how tight is the swash ball supposed to be? I'm referring to the metal ball in the middle.

Mine is fairly tight that if I stuck the end of a main shaft in it, the shaft wouldn't fall on its own weight if I turned it sideways.

That is far too tight, a little drop of 3 in 1 or machine oil will sort it out well.## Inteligence is knowing a tomato is a fruit...Common sense is not putting it in a fruit salad

Since it is second hand, are you certain the shaft is true? Have you tried rolling it on a flat suface (ie a thick glass table)? If it has a bend or has been crashed, that may be the reason that it is "tight" and won't fall.

As a side note, whenever I build a heli, I always clean the shaft real well with CLP Breakfree and do the same to the inside of the swash. There is a certain amount of "Break in" with a new bird in my opinion, where things will loosen up after 10-15 flights. Never know where she's been when it comes to a used bird so you might want to replace the shaft all together.

The shaft is true.

It's not that it won't fall through the swash ball freely. That is does.

It's when you try to pivot the center swash ball using the main shaft as a lever there is high resistance.

Either way, I was able to obtain a brand new swashplate and it is also snug. Not as tight as the used one, though. I figure a few flights will loosen it up.

I've just never had a heli where the ball wasn't totally free in the swash.

Oh I see. The only thng I can relate to that is a Trex 450 Sport I put together a couple months back. If I recall, it was a little tight, as well, pivoting on the swash. Flew fine.

The less resistance there is to the ball moving, the less load the the servos are under before you introduce the flight loads. This will lead to less current consumption and will probably maximise servo life.
Obviously you dont want it so loose that there is slop as that will lead to wandering.
