Default blades slipping

My blades keep moving when I slow down the rotor speed, should I glue the blades or should I get new blade grips, I have a EP Concept, No more stock foam blades, I have the MS Composite blades now, does this require different grips or glue?
I tightened the blades so much that I squashed the blade grips flat.

Don't glue them...they need to be able to pivot n case they strike something. This helps reduce damage to the main shaft and gear train.

Most helis... the blades pivot relatively easilly. The inertia (centrifugal force is really inertia) of the blades auto-aligns them with the head when the rotor is at speed. No big deal if they seem to pivot some as the head slows. Add throttle, things will line back up on thier own.

I posted this in the Kyosho section, but nobody owns one that can help me, so i'll repost here,

After I got my heli, I did the setup like the manual said, and as long as the rotor blades were across from each other I had no vibration at low rotor speed, well, I crashed from a 3 foot hover and broke my foam stock blades, I got a new set, but these are the MS composite blades, I also got a better pitch Gage, It's the Robart's pitch meter, I did the setup, now here where the problem is,

20% rotor speed, I have it set up as 0 pitch,, I'm a beginner
when I hit about 30-40%, I get such a bad vibration that it will knock the blades outa whack, also at this speed the blades are outa track about 1/2"-3/4".

60% rotor speed, the blades are in perfect track, and the heli starts to hover,

I'm having a hard time trying to keep the heli in a good hover without having to monkey with the sticks, "I'm inside no wind"

could I have a bent main shaft, or the blades out of balance?


Thank you for answering the question on how tight to put the blades, but during rotor slowdown, they have swung and hit the boom, putting 2 nice dents in it, thats another problem

I do not have one, but from experience I can tell you that if you broke the blades you have also bent the spindle. Take the spindle and the main shaft out and roll them on flat surface. Also, if you've flattened the grips I would change them right away! don't try to fly like this! you don't want one of the blades flying out when hovering! Out of shape grips could also cause the tracking problems.

well I started the dismantlement of the heli, I disconnected the rotor head and all the links, I then hooked a battery up and turned the shaft using the motor to drive it, I saw no wobble in the shaft,
I'm going to look deeper in the rotor
