Helicopters swing effect? why??

Hi guys!

I have a question that I have never solve on helis and want to know if theres an explanation for this issue.

I had a 600, 550, 500, 450, etc... and on every size I experimented sometime a pendulum or swing effect on the heli, but I see it only happens when doing sport flying, by that I mean, at kind of low rpm... I didnt concern too much about it because most of the time im flat on 100 throttle, but recently, I bought a 450 sport super cheap clone and testing it on my backyard It started to do the same effect on normal mode.

Please dont say that it happens because it is a clone, that happened to me in every single 450 to 600 heli I had with the exception of protos 500.

I have been four years flying helis now, and dont know where is the swing crew to adjust...

Any idea???

Low head speed.

My BL mSR X even does it if I'm flying below 33% throttle. All about the head speed. Check to make sure the new 400's head speed in normal mode is what it should be.
