I was never to happy with the head block being perched at the top of the main mast, with the Jesus bolt through the first hole on my N5. There was a fair bit of movement that you had to try to stop by squeezing the block onto the mast with one M3 bolt and nylock.

So, when I got my N5c, I decided after it was mainened and was flying well I would change the head block position and see how it felt. I bought some turn buckles from Midlands which are around 16mm shorter than standard, and then installed the head in the top hole. the head now mounts 16mm lower, so I had to reduce the length of the pitch rods from the arms to the swash. This was a bit of trial and error untill I felt the swash would sit at the right level for +-12deg, and with full cyclic and pitch, the swash is just away from the top bearing support, and the swash driver above it.

The results are a much tighter fitting head on the main shaft, and also the heli rolls quicker and tighter. There is still bags of room between the blades and the boom, so no fear of a boom strike.

One of the guys I fly with moved the arms from seprate base to the head block by bolting the arm to the head block using the hole that the clamping bolts are in. He placed a steel washer between the arm and the head block. This eliminated the seperate base and two bolts leaving him plenty of room for the swash.

That is the beauty of this head design. I run my head in the middle hole. I have not tried the bottom hole yet.

I am running the head in the lowest position on my E7. You do need new push rods. Easy to find the Ti rods these days.

What length is the length of the turnbuckles for the lower position?

You can also do this.
Parts needed are two Thunder Tiger 50 motor mount steel tapered washers (PV0107) and two 25mmX3mm bolts.Tapered washers go between the head block and arm/bearing.

Now that I like!!

Can the 3mm bolts be tightened enough this way, as they are the pinch bolts for the head block? If they do fully tighten up, this is a great way of getting zero phase and a very neat design.

Nice one, thanks for sharing.

Yes, The 3mm bolts can be tightened down with the use of the steel tapered washers. I had to grind the end of the main shaft to get the head block down.

I will get more pics tonight and post them.

Thanks for the part number, but it's a whole engine mount kit.

Looking at my spare head, I can machine 2 spacers that can fit into the holes flush with the outer edge, and then bolt the swash followers to that.

Great, thanks for the close up pics.

I was wondering if the tapered washer could be mounted backwards, so it locked centrally in the existing head block hole. This would also bring the arm in slightly to the block. What do you think?

You can get just the Thunder Tiger washers without buying the motor mount. The part number is PV0210.

Lowered the Head this weekend and mounted the followers directly to the head block and flew it yesterday. I already liked the N5c now I love it. Guys you should definitely try this out.
Todd thanks for sharing
