After assembling my new Ely-Q competition I noticed how tight the main blade grips are and was wandering if this was normal. I'm assuming they will loosen up after some flights. Can't wait to get it in the air. The quality of this machine is great. Great aluminum and pretty much not a single bit of play in the parts. Can't say the same for my T-rex 600. As for how it flies, can't say anything yet since I haven't flown it. I will get back on that part.

the main blade grips may be tight if the dampers are not all the way in. i would take the stock dampers out and replace them with the 80 durometer red ones from the raptor 50, much smoother.

mine are also very tight, too tight IMO. I'm going to take the dampers out and shave them down a little on each side. They seem to be flush with the hub so I think they are in all the way but the head is too tight.

Heya All,

If the dampers are all the way in, and the blade grips are tightish and notchy do not panick!

This is because the grips and the thrust's are not "loaded" Pull on the grips and twist em notice how there not as tight and are free running? this is because the Thrusts are loaded..

Now you can imagine how much force the blades will load the blade grips and thrust's so it should wear in after a hand full of flights!

Regards
Callum

yea, but once the heli spools up and gets some head speed, it will loosen up. if you grab the blade grips on each side and pull outward on them, they will become smoother. i wouldnt shave any material off of the dampers because you would have to do it on the outside of them. i just swapped the stock ones out for the r50 red ones and it smoothed out the heli well.

One way to help get the stock dampers completely inserted is to add a bevel or rounding to the inside outer edge (the side toward the head button) by sanding them a little, or shaving a little off with a razor blade.
When I say taking off a little, I mean just a little. I ended up trying the raptor 50 red dampeners. I can say I like them. I do plan to try various methods of working the stock ones back into place. One of those methods will be to shave or sand off about .5mm off the head button facing side of the damper, changing the length of the dampers by .5mm.

The Raptor Red dampers are about .8mm shorter than the ElyQ stock dampers and seem to have a much more "free" fit. By free I mean snug, but it doesn't take a 9000lb. elephant to help you insert the dampers and spindle like it does with the stock ones.

well, thats just it, some are just fine and some are having problems. replacing the dampers with the tt 50 red dampers is a good move for this heli

Thanks for the advice, I think the tightness is good for now. After a few flights, I think they should loosen up.

You would think they would loosen up, but mine never did. Even after 4 gallons of fuel. I can agree that in flight there is a ton of pressure on the head which would most likely take out the notchy feel.

That being said:
None of my other helis have notchy thrust bearings when I tighten the spindle bolts. Therefore, I always assumed that any notchy feel in any head design would be unacceptable. With the stock dampers pushed all the way in (I did it with a vise), each spindle bolt had to be loosened about a quarter turn to remove the notchy feel. I was not comfortable with that. The Raptor Red dampers fully inserted did not produce the notchy feel when I tightened the spindle bolts all the way, and there was no lateral play in the head. The head is tight, but moves freely.

I had tried 2 sets of stock dampers and 2 spindles to make sure I didn't get a buggered batch with the kit. They produced the same result.
This tells me that the tolerance is off somewhere. With the stock parts either the spindle could be longer, dampers shorter, or flap collars shorter. The latter 2 are probably cheaper to address in manufacturing. According to my measurements the total measure of tolerance required is off by 1.5mm plus or minus .3mm laterally along the spindle on my heli.

alex is right. with the stock dampers being so hard, almost like hard plastic, they dont give any when locking down the spindle. all dampers have some give to them for this reason. a simple replace the dampers with the tt 50 red 80 durometer dampers would resolve the problem.

I've got a few flights down on this heli and I love it. Very fast cyclic with the direct swashplate mounts and it tracks very well also. Seems to fly lighter than my T-rex 600. It has more go with the same equiptment. And as for the head dampeners, they did loosen up. I don't know about everyone else but mine are definetly way smooth.
