New Tail Rotor Assembly for my E620 SE.....

[rickc]

I received a Tail Rotor Assembly this morning from KASAMA. I installed it right away on my E620 SE. The craftsmanship is excellent, slop free....

In some previous posts I seen that some of the other Grips pilots were trying during the development stage were longer which made the need to run shorter tail blades. With the Kasama Tail Rotor Assembly I received today the grips are the exact same length as the stock TT grips. (35mm) So I installed my 95mm blades right back on. I think I was sent the finished product ready for marketing. You can see the assembly and the price here. www.kasama.com

Here are some pictures.

Thanks KASAMA.......

I think you missed the Food Network forum. You may want to post it there too. :mrgreen:

Just spreading some pics around of a nice product, 1 thrust bearing 2 radials. Nice improvement. I thought others should take notice of a very nice upgrade.

I found that the Pitch Links need some fine sanding on them to free up the movement of the pitch slider with the assembly of the Kasama grips. This just takes a few mintutes and the results are a very free assembly with no slop. I'll enclose a pic of what I did.

So if they made the od of this sleeve a tad smaller this sanding would not need to be done correct? The should just do that for future tr kits being released imho. Your process is simple and easy to me, but to some it may be abit of a hassle. Just a thought that Kasama should modify his end to accomadate the existing.

I think it may be intended this way, Kasama does not like slop at all. Just like the Kasama head assembly, we needed to file the links to fit on the arms for a precision fit. This sanding of the pitch links only takes a few minutes. I hope he leaves things as is and just explains what to do. It's a zero slop setup, great improvement over the stock assembly.

What links did you file to fit arms....?

[rickc]

The plastic washout links, as per the instructions, or email I was sent . The ones you chose not to use the set screws on the pins if I recall correctly.

Kasama Head Review
Written by Ron Henry
Friday, 04 August 2006
Having put several gallons of fuel through the heli since installing the complete head, I decided to write up my impressions so that anyone considering it would have another pilots opinion.

------------------Build Impressions------------------------

First of all, the packaging, fit and finish of all the components is second to none. Everything goes together very very well and the tolerences are on par with heads that come with FAI contest machines. Flanged bearings are used in the locations that pivot and carry a load such as on the bell-hiller mixing arms and washout arms. This makes for a very tight system and one that'll stay that way as more time is put on the components. One assembly note that may not be 100% obvious to everyone is that the radial bearings to metal grips is slight interference fit. So you have the heat the grips up before installing the radial bearings. When I did it, I put the bearings in the freezer and the grips in the oven set to 350 degrees for about 10 minutes. The bearings then dropped right in without issue. Doing this will make getting them fully seated easier. You'll know that they are when you're able to fully tighten both spindle bolts and the grips still rotate freely just like stock. You also will want to lightly file the inside of the plastic arms that connect to the washout arms to get the fit perfect. They'll go in without the filing, but it'll be a bit snug. A few passes on the file on the plastic arms will result in a tight, slop free fit.

Oh yea I didn't have to do those.
