e-Mikado Logo 400 500 600 > Stiff Blade grips

Hi,

My blade grips are really stiff to move on my Logo 10, All i've got is the shaft through the haed and the 3 O rings on each side smallest one nearest the blade grips. The blade grips move fine on the shaft but as soon as you tighten the M4 bolts the blade holders hardly move.

Any Ideas

Also my tail blade grips move fine until you connect part #2450 is it worth changing it to the upgraded version #3030 (i think) ?

Do you have the thrust bearings on your helicopter? How much do you have to tighten your blades? Are they too thin at the root so you have to tighten it too much? I don't see how tightening your blades can make the blade grips hard to move?

It isn't necessary to change them unless it broke? I would just wait until it broke then change it to a tail pitch slider from a 30 size helicopter, like a Ergo 30 or something like that. It works great and it's stronger then the Mikado ones.




Take Care,
Cheers, Patrick

Yes, I recommend getting the upgrade tail pitch slider (part# 3030). I got it for mine as the stock one didn't move very well at all, it had very sticky, movement and didn't return to neutral properly. The upgrade made a big difference, but still wasn't 100% right, so I oiled the tail shaft and now it works great. I also heard the stock one can break very easily.

Cheers, Hayden.

Patrick:
I don't think the Ergo30 TP slider will work with the stock Mikado tail blade grips. I took your advice and mounted the Quick50 metal blade grips but found that the stock Mikado slider links (both orignal and #3030 upgrade) would not stay on the blade grip link balls due to fact that they were not angled properly for that blade grip. Your suggestion to try the Erog30 slider worked great and it is a nicely made piece.
I would think then that the reverse is true as well - the heavily angled Ergo link on the slider would be almost impossible to secure on the stock Mikado balls.
You apparently have hit upon an excellent hybrid adaptation and I would just suggest that anyone interested upgrade both parts as they fit and fly very well together. Great discovery. Thanks!

(BTW: Did you find that the TP slider arms tend to hit that extension the bell crank mounts into on that Neeno tail rotor housing? You surely have to use a gyro with servo limiting like the Fut401 with that config.)

No thrust bearings, when its all assembled shouldn't the 2 M4 blots be tight up against the washer and shaft ?





Would of thought there would be another washer between the first O ring and bearing, could try some grease ?

As the reponse to your post on LogoMania said, it will must likely be just fine. And, just how stiff is stiff? If the blade grips are nice and free when not up against the o-rings then it should be just fine.

And, yes, the two M4 bolts should be snugged up to the spindle, but not overly tight. Use a dab of Loctite as indicated.

> maybe I should upgrade to the thust set ?

It will not change this situation. But, if you plan on using a head speed higher than 1600 RPM, you do need the thrust bearing upgrade.

Ray, you sure the tail pitch slider arm hits? Do you have a picture so I can see where your talking about? I looked at mine and I can't see anything that hits in all positions of the tail pitch slider arm.

Take Care,

I used the Ergo 30 tail pitch slider with the stock Mikado blade grips and they work great.

Did you actually go through the trouble of removing that metal tail assembly and remounting your stock tail to prove that point? But you are correct it looks like a fit - Now how about a photo with the stock Mikado TP slider on your Quick50 metal grips! I couldn't make that config work.

No that was a picture before I got the metal tail blade grips. I broke the stock tail pitch slider and found a 30 size tail pitch slider in a junk box so I thought I'd give it a try and it worked.

I don't think I'll try the stock tail pitch slider with the metal grips, too much work. I trust you that it doesn't work.

Take Care,
Cheers, Patrick

That one caught me off guard and caused a minor crash before I stuck on the 401

I've got the thrust set #2345 is this right



It didn't come with #952 washers ? do I use all 3 O rings ?

Also the shaft is very stiff to get through the bearings.

I just finished putting my Logo 10 together last week, and the head was a pain in the ........
My problem was getting the bearing all the way in. They were a very tight fit, and they go in farther then I expected. I didn't want to damage them while installing, but once they were all the way in their place, the blade grips were fine.

If my wife finds out how much these things cost, she's gonna kill me!!!

Yeah, I don't know about the shaft that you have, but the thrust bearing setup (which came in my kit) doesn't clamp down on the bearings to cause binding. They are a snug fit in there, but once they are flat and seated, the screws should not restrict any movement of the head.

I had the same question about that assembly (even with the thrust bearing) and I asked the guys in the back (in Hacker and Aero-Model) and they confirmed that if the bearings are seated correctly with the thrust bearing setup, the screws will not cause binding.
