If the .30-.50 unit works well I have an all aluminum 50-60 one to sell/trade at reduced cost.
What is it exactly that you have to sell? Any pics?

It's easy to find an excuse to do wrong. Hard is not to find an excuse to do right.

Sorry , no pic, but I have the Century Diamond .50-.90 5-blade all aluminum head. Never used just mounted to 10mm shaft. I only plan to sell/trade it if the Diamond .30-50 5-blade fits better and I hear good reviews. No since getting rid of one head for one with same fit issues to a 10mm shaft.

Thanks,

MadDawg

Just fitted one to my Trex 600E. They do require some work. I used .0015 shim stock between adapter sleeve and the head, and a piece of .001 shim between the shaft and the adapter. Fits really nice now. I'm using 550 blades simply because I had a couple of single blades already. I painted the heaviest and weighed it. I then painted all the rest of the blades to that weight. Then I found the heaviest after painting using the blade balancer. Balanced all the other blades by putting each one on with the master and adding paint until balanced. Took a while, but they are perfect!

What local vendors do you get shim stock from? Also, is shim stock the technical name I would use when asking for it?

Also, like the painting method for balancing. Provides a better look and no tape to deal with.

Thanks,

Shawn

You can get at a "real" hardware store...not a big box store.

Also from Grainger, or similar stores.

I used SWE CF blades on mine. 550 blades will be about 12 mm shorter than 600 mm blades on the stock head. 530 mm blades may be the way to go. Less torque for the tail to overcome.

Seems 530mm blades are a little harder to find. I have found Carbon Fiber Heli-max. Know of any others?

Alan, what sized blades did you use? I know most builds have been using the 530mm with the larger Century head. So, I'm guessing these will still be a good fit.

I'm using 550 blades, since I had some single blades to choose from. My son flies for Outrage RC and has an Outrage 550. Thus the selection of 550 blades for mine.

This is what I'm using:

NHP, SAB and Century/Funkey do 530mm blades. I'm putting a set of Century ones on my Trex600e powered MD500.

Anyone have the instructions for the Century Diamond .30-.50 5-bladed head. I can figure out most of it but the order of thrust bearings and washers needs clarification. I'm guessing the large silver/steel washer goes in first next to the bearhing, then the thrust bearing set, then the smaller black washer then the bolt to hold it all in.

Another question is the thrust bearings is there a specific order they should be put together and/or certain side going in?I seem to recall when building the Trex600 head the thrust bearings went a ceartain way.

Thanks,
MadDawg

There are a couple of items that I'm not happy with. First, 4 out of 5 thrust bearings had 2 outer races.
WrenFlyer,

Can you tell me how to know what the thrust bearings should look like? 2 of the 5 grips I have, do not spin freely when tighten. When I loosen the hex bolt they are fine. So I think I have possible thrust bearing issues and need to know what to look for. Maybe I have them backwards or something.

Thanks,

MadDawg

Remove one of the free spinning grips to see what the thrust bearing arrangement is. Then remove one of the problem grips and do a comparison look see.

One of the thrust bearing races should fit very loose, this one goes on the inside. The tighter fitting race should go on the outside, next to the bolt. In my case, there were 2 outside (Tight) races in the sets. I happen to have some spare Gohbee thrust bearings to replace the bad ones.

Thanks will take a look tonight as I have some my time to work on the Heli. Unfortunatly if I do have improper thrust bearings it will be a call to support as I don't have spares unless thes ones on the original Trex-600E grips work.
