Hi

I am still putting my EVO together. I noticed that the tail spindle can move when I pull and push it, by about .5mm

Is this normal ? or should it be slop free. Short of using a washer inside the tail box, I don't know how to get rid of the slop, or whether I should get rid of it at all

Help...

Thanks in advance

Put on thin shims so that it doesn't move at all. I did so with mine.

Its normal - its been discussed here many times. As long as you assembled it according to the instructions, it will work great. Centifugal force will take the slop up when you spool it up.
The shims will defeat the design of the tail and cause premature wear of the bearings.

Guess what? I just saved a ton of money on my Auto(rotation) insurance!

I think he means the tail shaft itself having play inside the gearbox, not the tail grips.

Outgoing shaft is the same.
Different belt pulleys.

Make sure you havent forgot the spacer #2521-061
(that goes between the bearing on the right side and belt pulley)

Yes, A shim would take the slop out and make it a little better. It will fly fine without the shim. Its just better to have it there.

Shim it. Just don't preload those little bearings with too big a shim. Some will sand away one side of the tail case and it will have the same result. I prefer to shim as I like to keep the case halves fitting around the boom nice.
The tail rotor shaft will be able to float when the point of zero pitch is reached otherwise.

I almost agree with Mr. Noodles. Check that you haven't forgotten the 2506-021 washer.

Also check that the tail is correctly inserted in the tail case and that the screws are tight.

My Evo has Zero play on the tail shaft.
