This heli difinitely needed a lot more R&D. I did all the mods that everyone discussed. But find more issues.
Tired of waiting for the torque tube. So I was going to finish the heli up and fly it this weekend with the belt drive. When setting up the pitch and cyclic. Started noticing how much the head is wobbling back and forth. All kinds of slop in all directions. Tried pinching the hub closed more. Because the bolt wont tighten it up and then shimming the sides. But having problems still.
Out of 15 to 20 heli's I've never had to do this..

Do they have a new version head coming out that actually fits? They could of milled down the bottom of the head and put a locking collar or something. It just seems like theres to much material there to pinch it on the main shaft.

Just frustrated

This is common to the Competition...there is a new head block on the way (please don't ask when ;o) but what I did was to increase the slot in the head block by 2-3mm. then pre-tension the headblock before installing on the mainshaft by gently squeezing the slotted end together (I did mine in a vice). Use a larger washer on the jesus bolt than the one they provide; the stocker eases its way into the recess when you tighten it up.
Don't tighten up the plastic flybar guides too tightly as this spreads them, causing the flybar to bind. And use M2 nuts on the mixing arm ball links - they will loosen otherwise...

You'll enjoy how it flies when its all together

Cheers

I ended up pulling the main shaft back out and using a vice on the head block. Then using a press to push the main shaft back in. Now it seems like it shouldn't loosen up later on.

Thanks for the tip on using M2 nuts on the mixing arm ball links.

The nut is supposed to recess into the aluminum when tightening the jesus bolt. Is you need to get the nut out after it is recessed it is as simple as taking a hex driver and inserting it through the bolt side to pop the nut out with a little tap. Once the nut has been recessed into the head, it makes it much easier to tighten the jesus bolt.

I cinched the latest head block I bought in a vise. I did not cut the slits higher and it works fine. On the prior head I had cut the slits higher. It may depend on your particular installation as to whether you need to cut the slits higher or not.

If you do not increase the slot in the head block, it will loosen up again. You can pre load it every 15 or so flights, or just simply increase the slots, and forget it forever.

I lengthen the slots 2 to 3 mm, and pre load it as well. I have over 100 flights on my head with 3 crashes, and it has not loosened up yet.

Hope this helps

My headblock is tight on the mainshaft, are you guys having trouble form new or after a number of flights?

May be it was certain batches that were loose?

Tim.

Again. Simple fix, 5 minutes of your time and it will go away.

I agree that you shouldn't have to do this. But I am here to help you guys. Increase that slot, and tighten the heck out of the jesus bolt, and you will have success.

I do work for the company, but I will not sugar coat anything, nor mis lead you, I simply want to help you guys resolve your small problems so you can get out there and get some flying done. And this is the easy resolution to a small problem. If you feel you want to try a different head block, simply contact the dealer where you bought the machine and request one, but I will warn you that you will end up with the same situation, even if it is tight in the beginning, it will become loose within just a few flights. The tolerances on the slot are off from the factory, so increasing it will do the trick.

Here to Help.
