Honey Bee 2 Yo-yo problems

Alright, I have successfully hovered my honey bee 2 for a whole pack and it is great. I go and hover it today and all of a sudden - the yo-yo problem that I have read so much about has started. I have not wrecked it or even had a rough landing. So I have a few questions about this after reading Aerohawks Esky CP thread about this problem.

1) This appears to be a seperating swashplate issue. Correct?

2) Will the expensive ($80 aluminum swashplate) fix this problem?

3) Does that plastic part in the head have to be sanded down?

From what I have read....
1) No, it isn't the swashplate
2) See above
3) The issue seems to be due to excessive friction of the part sliding up the head to change pitch. Various attempts have been made to lessen this friction. Aerohark appears to be having the most success dealing with the issue.

Hope this helps

when I notice strange handling,I take the head completely apart,make sure it is true,and PACK the pitch slider and flybar slot with heavy lithium axle grease.

I usually get about 10-15 flights before re-greasing(by that time,I usually need to straighten the shaft,too).

I still dont notice any porpoising(did I spell that right ),just gets sluggish on the cyclic.

What is the best way to take apart the head? I feel like im going to break it.. Any pointers on getting the thing apart? What tools do you use? Aerohawk1 - you are a guru.

When i had to replace my head witha new one i notice that the head had alot of play. Just take some fine grit sandpaper and sand down the head. No problems after that

be firm,but gentle...

remove blades first,then flybar,disconnect pitch links(oval ones) from swash(no easy way to do this,though I use a flat,wide screwdriver placed between the two and give a firm twist).

remove pin,remove head.

disconnect pitch links(threaded) from blade grips.
unscrew blade grips...thats the jist of it

i'm working on the theory that the yoyoing is caused by the flybar rubbing on the inside of the pitch slider causing sticking. I've packed it with lithium grease, but it didn't fix it. I've only just finished rebuilding my esky after shelving it for a while.

Try sanding the inside of the pitch slider (ie the slot that the flybar goes through) so it's as smooth as possible, then grease it as Aero suggests.

That's what i've done and will be testing it soon. Hopefully that fixes it.

Used a metal nail filer to sand the inside of the pitch slider where the flybar goes through. Works like a charm. Took about 5 mins to get everthing working freely. Just thought I share it with you guys. I finally went to brushless setup with mines. I can get rock solid hovers and no yo yoin problems. My head speed is way over 2000. Too bad I sold it last week. Moving on to T-Rex. I spent countless hours on the honeybee to fix the problems. Got it working rite then one of my flying buddies wanted to buy my heli so I sold it to him. BTW i used the century hummingbird full semi main blades and FFF was amazing. I think these blades flew way better than the stock blades that came with the heli.
