Dampening Microheli blade grips
I installed the MH blade grips on my 450XL. Used the standard two O rings and metal space ring. They feel quite a bit more mushy Than the stock blade grips. I'm not sure why they would be, but they are. I tried to add the spacer that came with the blade grips, so have two O rings and two spacers per side, and that made them too solid, no give at all. I tried them with three O rings and one spacer on each side, and that also made them too tight. Not sure what to do.

Hi kileak

The QNC head is designed so that you can have options of using single O-ring on each side for better stability or 2 O-rings on each side for faster response for 3D pilots.

When you use single O-ring option, you need to use the aluminum spacer to replace the space of the second O-ring. When you use double O-ring option you do not need any aluminum spacer. In both options you need a delrin washer on each side.

Please take a look at our instruction that is included in each package.

If you have any question please feel free to contact us at support@microheli.com

We glad to help out.

You must not have the two end screws in tight enough or are not using the metal head piece. I have the metal head piece with the mh blade grips (two O rings and the smaller plastic spacer per side. Seems fine. My main issues is with getting the blades in the grip itself. Can't really get a good fit for the blades.
I've tried one metal washer (they supplied) per side and it helps but it's not as good as I'd expect. two of those metal washers per blade grip (one on top and one on bottom) won't fit and is too tight.

Tiny-flyer,

All of our washers are CNC machined to ensure top tolerance. We designed these washers according the the stock plastic blades. If you use wooden blades or some after market blades with different root base thicknesses, you may have to find some other washers or just simple using some sand paper to sand down the wooden blade a little bit, it would fit just fine.

The wooden blades are not always at constant thickness, so with just some simple work you can fit it in easily.

Our main blades are designed to work with stock main rotor hub too and our main rotor hub is designed to work with stock blade grips too.

If you have any questions just send us email to support@microheli.com and we will work with you.

Best regards,

I have the align metal hub.I ended up using a small bearing from the align plastic blade grips as spacers. Makes it pretty stiff, but has some give to the damping now. I'll try it if it ever stops raining. I had to spread the blade grips open slightly to fit both of the blade washers.Seems the washers should have been CNC machined to a little thinner top tolerance.

On a different note. Tonight I installed the upgraded front tail drive shaft from you. Its a bugger to get in without completely splitting the frames but doable.
The only complaint I have is that the allen key and the allen head grub screw do not fit together very well at all.
The key does not get a good bite into the metal. This makes it very difficult to get the grub screw to seat with any positive assurance. I used blue Locktite and will test it tomorrow.
Hopefully it will hold without coming off like the Align original one did.

I had a similar issue with the rear pulley and shaft. I decided to get the Align grips instead. I don't like the washers you have to use with the MH ones. Now I have to try to sell the MH ones.

You are selling because you don't want to install a couple of washers? It would seem this decision should be based on performance of the piece or possibly even asthetics but not because you don't like how many peices there are......am I missing something else?

My main issues with the mh blade grips is the support arm for the ball link has two socket screws holding them in and one is loose. I cannot locate a stinken allen wrench small enough to tighten these. Therefor these have rendered themselves disfunctional until I come up with a remedy.

Unless mh can mail me something that fits these...

It's not just because of the washers themselves. I had to spread the grips slightly to make the washers fit. The grips now don't seat quite right on the blade roots. It's hard to get the correct tension on the blades. Then there is the issue with getting the correct damping. It seems kind of jury rigged to use bearings as spacers like I did. I could find some washers to use as spacers though. It's just a matter of how much fiddling do I feel like doing. I'd rather just have a set of grips I could put on and go fly the thing without all the adjustment issues. I think it would be better to have to clamp the grips slightly than to spread them, but I'm no engineer.
