I have a hbfp and it has a bad shake, ck,d flybar seems ok,ck,d blade tracking looks ok, It shakes pretty bad, worse when I change direction like forward and reverse, left and right also tried blades tight and loose, tight is better if I get the blades lined up perfect, but takes several times to do that, has a superskide from extreme and a battery/reciever mount that fixed the balance problem any ideas would be great at this point!

Vibration is a common problem that can be caused by many factors.  Most are from the rotor assembly.  Here is a checklist:

A common problem with RC helicopters is vibration. Excessive vibration makes hovering more difficult, uses up power, causes "gyro drift" and increases wear and tear. Several things can cause vibration, which makes it difficult to identify its source. Below are some of the possible causes:</p><ul>[*]Check the rotor core and look for cracks in the plastic escpecially on the ears were the two bearings hold the rotor blades.  This is usually the culprit.[*]Use the same blades for replacement. [*]Look for small cracks or chips on the blades.  This can cause  vibration as one blade is cracked versus the other blade.[*]Crooked rotor blades. The blades should be at right angles to the fly bar.[*]Rotor blades aren't tracking. They should both travel in the same plane.[*]Rotor blades too tight. If the blades are too tight, they can't self-adjust from centrifugal force.[*]Rotor blades are too loose. Adjust the blade grip screws for these two problems.[*]Main gear missing teeth.[*]Flybar paddles misaligned. The paddles should be nearly parallel to the swash plate, preferably 0 degrees.[*]Make sure the rods from the skids are fully seated and the rubber sleeves snugged up to keep them from shifting. I added a rubber band to mine to keep the skids snug.[*]Finally, you might to check if the main gear shaft is bent.  You will have to disassemble the rotor assembly to get to the shaft.[/list]
Hope this helps.  You will be a mechanic in trainning after this.

Only thing that doesn,t look quite right is fly bar paddles, they look like they are tracking good but they don,t look 0 degree,s,hard to tell ?

I have a HBFP and had the vibration curse for some time. For me the problem was the crash gear. It apparently induced a harmonic vibration which caused the whole heli to shudder. When I took them off it smoothed out immediately. The only other times it happened acutely was when I broke one of the ring links or one of the hub pitch hinges off (the bearings for the head) causing it to vibrate until I replaced it. It did, incidentally, still fly and I therefore didn't notice it until I carefully inspected the head.

Also see this for excellent methodical advice on eliminating vibrations:

One of mine had a shake for a while till I figured out it was the flybar and paddles. They have to balanced also. Easiest way is to remove the rotors and tip the flybars back and forth noticing balance. Shouldn't be any binding here either. I use a metal flybar and measure everything but obviously that's not good enough. Check the balance.
