New build Trex 500e, serious amount of heli for the money

[tomatwalden]

So here's a thing. After posting the vids by "Freddy" - I went back and had a look at my tail. Popped off the control arm to see how freely it moved. To be honest, mine had some binding too unless I undid the screws on the tail slider way too much. The Align instructions mention not to do these screws too tight, but I just wasn't happy with mine. So I tried something ....

The screws - in particular the inner ones attached to the actual tail slider are a barrel->thread type. ie. the thread is only at the bottom part of the screw with the top part being smooth that should turn in the holder. I applied threadlock into the receiving bit of the slider that the threads went in to, but then applied grease to the barrel of the screw - to try to help it turn.

Now, I've got the screws in nicely home and tight. But with the grease in the non-thread bit, the tail slider moves super-smoothly!

I'll try to post some pictures later to better demonstrate what I mean.

Hey.

What you'd probably have found is that you had loctite find it's way into the dog bone link assembly, which then creates a stiff tail control slide assembly as it goes off.
During the build of the tail rotor assembly it is very easy to have loctite enter these screw holes and it's surprising how much this can effect tail movement. By adding some grease you are filling the void between screw and dog bone link and so helping eleviate the possible problem of loctite entering and causing a problem.

Firstly, thanks for all the replies...I just got home from work and having watched those vids, first thing I did was check the smoothness of the pitch adjustment, It felt ok mut with the slightest amount of binding at each extreme. so I greased the slider and backed off slightly each screw. It is now as smooth as silk, and during a very brief test hover the tail is rock solid, with the gain up to 80%, no wag at all!!! Fantastic, I can't wait to get to the field tomorrow afternoon and get this baby flying properly...
Thanks again guys.

glad it's working well! Keep an eye on those screws just to make sure the threadlock is still holding and that they don't work loose!
