Nov 02, 2022     Finding Elevator trim problem - (12 hours)       Category: Controls

I wanted to set the trim parameters with the G3X but was having issue with the sensing. I had to try to trouble shoot the problem from the wiring connections thru the G3X setup... very tedious to find the problem. The trim would move normally on the stick and the G3X test panel but not indicate position consistently. Finally, with multiple passes thru the wiring the offending pin was found and corrected

Now that the wings are attached it is time to get the flaps and other control surfaces connected. Started with the flaps and worked my way thru the ailerons.

  Dec 01, 2020     Flap Motor & Aft control stick mount - (3 hours)       Category: Controls

Installed the flap motor. After I lay out the wire bundles I will go back to this to wire up the connectors.

Added the aft bushing mount on both control sticks.

I have found an issue with the autopilot aileron servo mount. It was supposed to mounted under the spar but it arrived unattached. I am still trying to figure out how to get this bracket installed properly.

  Nov 18, 2020     Rudder Cables rear fuselage - (4 hours)       Category: Controls

Been off the build for a week. Back to work.

The cable go thru the center fuselage, by the springs, and cross over each other to the rudder. This was to install the rivnuts for the guides . Be careful installing the springs! One got out my hand trying to pull into place. I'll get them installed tomorrow.

  Jul 31, 2020     Throttle & Brake Quadrant - (10.5 hours)       Category: Controls

7/31/20

My 1/8 BSP (British Standard) die arrived today so I changed the 1/8 NPT to 1/8 BSP and fitted to the Parking Brake valve. The Throttle/Brake assembly was completed with the cable bolts and brake line fittings left finger tight for final installation.

7/26/2020.

Added the 1/8 NPT fittings to the hand brake cylinder but I could not fit to the parking brake valve. It was a different thread.

An email to the factory got the following response:

>>>The thread on the fittings is 1/8” NPT and inside the valve is 1/8” BSP – the 2 threads are almost the same but don't quite fit. What we do is get a 1/8” BSP die nut and clean the thread of the fittings. Apologies – it should be in the manual.<<<

So off to Amazon to get a BSP die.



7/24/2020
Assembled most of the throttle and brake quadrant. This is a steerable nose wheel with a symmetrical hand brake system. I will add the brake line plumbing tomorrow and the parking valve.

As is throughout the whole kit ALL M3 Rivnuts are to be upgraded to the M4 size this has required much time reaming the M3 sized holes to the larger size (and the screw holes as well). This assembly was 18 rivnuts alone and I know I am approaching over 100 holes reamed out....very time consuming.

  Jul 28, 2020     SB # 18 Insufficient swaging of oval sleeves on the rudder cables - (4.5 hours)       Category: Controls

7/31/2020

Completed the SB#18. This is a 2 part process: first, inspect the crimp width of less than 8.9 mm and then to put corrosion resistant grease on the fittings. It was not required to re-wrap the ends but I did anyway.


7/28/2020

Received a SB for inspection of the Rudder cables crimps. So a read over and inspection will push aside the next few days plans. I will need to order some materials to comply.

At least I get some of the SB's during the build so it is relatively easy to take care of them. The numbering system is a little odd even though it is SB#18 it does not mean there are 18 SBs for this particular model.

  Jul 14, 2020     Setting control Tubes (part 2) - (6 hours)       Category: Controls

After compliance with Service Bulletin regarding the elevator stop brackets I then completed the installation of the Bushing parts and part of the seat mounts.

Also, The factory has decreed that all M3 rivnuts should be M4 size now. So much time has been spent reaming the holes before setting the new size.

  Jul 01, 2020     Rudder Pedals - (6.5 hours)       Category: Controls

Assembled and installed the rudder pedals, stops, and rod ends. The mounting plate was already installed in the fuselage even though they sent me the plate anyway. This made installation a bit difficult as it would have been easier on the bench and the rivet the entire assembly in place. I made good use of a swivel head hand rivet gun
