A student of mine asked me to help him get his blade setup after he had trouble getting the tail adjustment working.

While I was at it, I decided to check his blade washers to see if they were sticking.

I found a few different things with his blade heli as compared to mine:

1) His screws which old the main blades on do not have nuts on the bottom. They screw directly into plastic. Mine came with 2mm nuts on the bottom of the blade mounting screws. I don't think this is an issue with this little heli, but I found it interesting that there was a difference. I don't see the nuts on the parts list. So why did mine come with nuts? Does anyone else have nuts on the blade mounting screws? Perhaps my blade is a male heli and my student's blade is a female version?

2) His head assembly was missing the small washer/spacer which goes between the O-Ring dampeners and the blade holder. This is the one with the little shoulder which should be towards the blade bearing. If someone else is missing this washer/spacer, then it could also cause a problem. I didn't have a small enough washer in my parts bin to replace it, so I just re-assembled the head as it was from the factory. I flew his heli and it seemed ok, but I told him to call Horizon and ask for them to send him the missing parts.

I belive Boyd is headed in the right direction. But, I have read many posts where this didn't help. I have what might be a solution if it makes any sence.
Let me start by saying this is my first heli.
After getting the grips loose I noticed on my bird: (from ouside in) screw, spacer,bearing, bladegrip,bearing flanged washer o-ring.
Would it not make sence to get 2 flanged washers for this?by getting this part?EFLH1162 (this would give you 4 total)
Since I have read that some are not having luck with this fix, and after about an hour of looking(and pulling).
Would it make sence to use the flanged washers on both the inside and outside?
It would seem to me that this will allow the bearing to spin free as a bird,as the head speed rises.
Make any sence?
I have some Photos on my regular site, of what I am thinking of.

I hope you can see. Like I said I am very new, but after seeing this, I had to ask.
I hope this is not out of line here.
tell me what ya think of it.
Hopefully I will be getting pat1162 tommorrow to try it out.

Your assumptions about using two more stepped washers is correct. Unfortunately there are no stepped washers included in EFLH1162.

My Posts This: Topic  Forum		On horizons site,part 1162 shows these washers in this blade grip set.
Unless there are 2 flat washers that come with the replacement.
See:http://www.horizonhobby.com/Shop/By...ProdID=EFLH1162

My Posts This: Topic  Forum		i also just got a set of blade grips and did not have the nuts. THis is actually a better design since it eliminate the need of one. THe hex bolt just go directly down and stays there.

$8.00+ seems extravagant to fix a problem that can be fixed for free. If you are concerned that swapping the spacer and M2 washer at the outer ends of the spindle shaft doesn't get you to a free moving collective (and it did on all 4 of the Blades I have), there is another way to save the $8.00. Simply take the two M2 washers, slide them on an M2 screw/bolt add two M2 nuts and tighten so that the washers cannot rotate. Chuck the bolt into your Dremel or drill and grind the OD down on the washers using a file applied to the spinning washers in the Dremel. Now you will have two small OD washers with a 2mm hole in the middle that will interface perfectly with the inner race of each of the outer grip ball bearings. Buy a couple beers with the $8.00 and pocket the change.

My Posts This: Topic  Forum		I just took my blade grips off to make the change of the M2 washer and the spacer and I found that there are no M2 washers? Just the screw than the spacer and the bearing. Is the M2 washer between the spacer and bearing a must have?

My Posts This: Topic  Forum		Bah, Since I don't have all the wonderful tools yet I bought the grips, so now I have 4 flanged washers for the bearings.
Also I didn't have m2 washers on mine either, just the spacer.
I have a spare set now
Thanks for your time and wisdome on this. Without it I would have never looked into it.
Thanks,

My Posts This: Topic  Forum		After taking the blades off, only one of the screws came loose from the spindle. That figures...so much for it being easy

So, being a newbie, what steps do I need to take to get the other side to break loose? What holds the blade grip to the spindle? If I remove the screw that broke loose, should the blade grip just pull off?

Thanks for all help.

My Posts This: Topic  Forum		The side that you took screw out...Pull grip off and push spindle thru and flip the washers and put back together and fly. You dont have to break both screws loose on the grips to do this. Have fun

My Posts This: Topic  Forum		I tried pulling the grip off with no success. I thought maybe there was something else holding it on.

I'll give it a shot...thanks for your help.

My Posts This: Topic  Forum		We did one at the field today. used two allen drivers, broke one side loose put a 1.3 driver in hole in the spindle, tapped on it and pushed the axle through about 3/16 enough to grip it with a small pair on vice grips between the opposite grip and center block ,loosened the other side and reversed the washers. Checked mine and it was assembled correctly, they probably fired that assembler because it was not assembled according to the plans.

It seems that the 'newer' batch of Blades are coming through without the nuts. This is a better design, it's lighter and you don't chance dropping the nuts and having a hard time finding them as I have a few times!
