I decided to glue the tail boom supports directly on to the frame. This was to ensure the tail boom is kept exactly horizontal to the air frame in general:

This is how I made sure the yet-to-be glued CNC supports hold the boom horizontal to the air frame:



I used ballancer bubbles which I taped horizontally to both the frame and boom:

And therefore, this is the end product of both the bearing case(s) mod and tail boom extension:






Edit: I needed to extend the tail support by 17 mm as I am running 453 grooved belts which I bought from Dave of Heliworkz.com. Only $ 2!!

Concerning the motor mounts - on this frame, the motor mount also comes with the mounts for the two front servos:



Therefore, when I moved the motor mount further to the front, the servo mount also moved, with no place for mounting!:


Yellow arrow is the original servo support mounting.

Well, the solution is pretty easy. I just lopped off the front section of the frame which I wasn't going to use, and use it to extend the servo mount:



Red arrows are the parts cut off, to make the servo mount extensions (yellow arrow).

Here's the finished product:



I added additional CA powder + CA to the areas around this extension, to ensure good support.

Next to be built is the guide rollers. I am running my tail via a belt driven directly from the main shaft. Therefore guide rollers became a necessity:

I bought these Align alum tubes (HS1188) from wattsuprc.com:



They were great for building the cross support to the guides:



I did not buy the stock Shogun V2 guide pullies as the shogun tail boom is only 9 mm compared to the Trex tail boom of 12mm - therefore 'pressing' the belt to go through a 7 mm guide (for 9 mm boom) appeared as an added unwanted friction area to me.

I've been having some issues with my 401 Gyro off late. Its keeping me busy and away from posting here. But I'll be back as soon as I'm airborn again (does that make sense?).

Anyway, good luck, and keep those skids light.

So with the belt guides in place, the frame is more or less fully modified. So here's what it looks like with the main gear, bearings and bearing case on:

Installation of the electronics could now begin.
The motor and two front servos went in first. I'm using JGF 400DH motor - very light at less than 50 grams, with huge 4000 + KV, and low 9T pinion.
I get great flight times with this motor, while the ESC and lipo stays super cool.



On the flip side:

For the three cyclic servos, I'm using HS 65s. They are great carbonite servos, high torque, and super silent. Movement is smooth which also translate to smooth collective control:

There was another item I didn't buy from Jeff of xmseller, and it was the aluminum spacers for the two front G10 supports (arrow):



These I had to cut myself from two of these Align alum tubes:

Now for the canopy mounts - I'm using standard Align Trex XL canopy. I think the stock shogun canopies are much much too small, and anyway, the way I install it, I don't have to take them off or on when I put my Lipos in/out:

For the top mounts, I use the Trex bearing case mountings:

Instead of using screws, I cut a lenght of the Trex flybar rod (the threaded ends) to make a long 'screw'. This screw not only holds the bearing case in place, it also has a dual function of supporting the canopy:

On the other side, I use the same mounts to support my eileron arm - so 3 multi-functions for this rod (yellow arrow)!
