To support the bottom of the canopy, I drilled two holes for the mounting screws like so (yellow arrows):




On mounting, I just bolt the nut (red arrow):

Well, I've been flying the shogun for a few weeks. Its real nice and easy to fly. Didn't think there was anything else to upgrade, until these guys ran out of hollowed shafts:

Without this cheap shaft to keep me flying, this bird is as good as dead.
I also figured that the #36 / shogun is a dying breed, and parts would eventually run dry anyway (or get waaay too expensive).

I therefore decided to move away from mechanical mixing cyclic control and make that giant leap into the fabled CCPM.

I bit the bullet and forked out my last 'upgrade' budget to get this:



And therefore, in the next few days, I shall elaborate on how my shogun got itself hybridized even further into a CCPM bird.

Some say that Align's metal head isn't the best (swash keeps coming apart), but I figured I'd go with the big guys, just to make sure I'll forever get parts.
After all, this is the ultimate and FINAL upgrade for this bird:

First off is the most difficult part of the mod - the installation of the Elevator servo and anti rotation bracket.

To ensure that the servo arm and its ball link is exactly below the swash plate ball link, I used a plastic servo mount (arrow) to make a temporary installation guide:



With the above, I could precisely work out the location of the servo in relation to the swash plate.

I could also figure out the height of the anti-rotation bracket support on the adjecent frame. The anti-rotation bracket is installed just above this plastic servo mount:



The support on the other side of the frame:


The height of these two supports must be exactly right, so that the anti-rotation bracket is exactly paralel and verticle in relation to the main shaft.

Using the plastic servo mount, I found that I needed to make a notch on the frame to enable the servo to be mounted snugly:

Here's how the notch functioned later:



I found it (the notch) to be absolutely helpful in ensuring the alignment of the servo is horizotal to the swash plate above. It also added additional side support to the servo.

Well, apart from CA holding this servo mounting on to the frame, the mounting screws for the tail belt guides also gives additional support:

Here's a view of the servo notch after the servo mount had been CA-ed on the inside of the frame:

Now on to the anti-rotation bracket.
Considering its a simple static structure, I didn't expect it to give so much trouble. Well, it did.
First, its location had to be JUST right, so that it could hold on to the swash extended link, at ANY pitch. On top of that, it had to clear the movement of the servo underneath. After I had gotten this two right, I found the fly bar rod could hit the top:



I'd say of all the parts going into this mod, installing the anti-rotation bracket was the hardest.

Well, to solve this, I cut off the top and rejoined it lower down. I used CA and nylon fibres to rejoin the two.

Whereas the bottom had to be cut/filed out a ensure free elevator movement at maximum negative pitch:

All in, the anti-rotation bracket took the longest to do - and IMHO the most difficult part of this CCPM conversion.

Still with the anti-rotation bracket - I drilled a hole on the bracket support to reduce weight and to enable easy access to the servo arm screw:






(Additional holes were also drilled on the frame itself during this time, mainly to reduce weight).

Well on with the Pitch and Aileron controls. I had to buy another set of the push pull arm from xmseller:

I therefore had two sets of this push pull arm to connect my servo arms to the HS1111 swash plate:

Positioning of the ball links for this push pull arm - (as well as with the elevator ball link) - is exactly under the ball links of the swash plate.

This is the best photo to illustrate the vertical positioning of the ball links to the swash plate - as best I could all are set at 90 degrees at zero pitch, and seen from above, the arm ball link to swash ball links are directly under each other:
