Instrument panel first switch on

An exciting moment. The G3x immediately found (over the CAN bus) the magnetometer (GNU11) and audio panel. I initially had problems recognising the transponder. Made a software update G3x V6.0 now. Then reinstalled the config file. Then it worked fine. Flaps, inside lights, boost pump. G5 all work fine. I have never used a G3x, so I spent some time getting to know the panel and adjusting the infinite number of settings! The G3x is an awesome piece of equipment. Found couple of errors in the wiring harness. The lane B LED and Lane B switch were wrong way around. Easily fixed by re pinning the CPC connector. The wiring of the IBBS 1 and 2 battery volts monitors were not made in correct locations. Rewired D connectors to set GP3 and GP4 on the GEA24 for IBBS volts. I had to remake four loose crimp connectors at the relays. Found a loose engine sensor probe which was giving an error on the G3x. All systems seem to be working fine now. (no engine start done yet) but only error is the magnetometer calibration not done.

Wiring

Been laying out the wiring harness through the centre console and looking to see how all the required lines will go. Especially how all the lines will go and not clash. Getting past the elevator torque tube. It’s very busy. In the centre console are: Rudder cables x2 Antenna coax x 4 placed in grey plastic flame retardant conduit Fuel lines x 4 used a 3D printed spacer for rudder cables Rudder cable x2 Wiring harness Pitot and AOA pipes Throttle cable Brake fluid header pipe Rear connections The magnetometer has to be fitted in the rear fuselage through an inspection hatch. Quite a fiddly job to do. Brass screws with locktite without dropping a screw that will rattle forever. Then fit a zip tie on the pr existing clamp provided by the factory, so that the magnetometer cable doesn’t go near the rudder cable. 28/2/2022 Tidied up the centre console wiring and added the pitot and angle of attack lines.

Centre Fuselage and Seats

First tasks, checking inventory for the quick build fuselage, firewall forward and canopy kits many items missing. The elevator torque tube was very stiff as assembled by the factory. Had to drill out rivets and file down and realign all 4 bushes. A few special tools are needed to drill around corners in a tight space! 5 hours. But hopefully will pay dividends in smooth flight controls later. Adding rivnuts to the inside centre console. Getting good at this now. Having a bigger rivnut puller certainly helps when it can get into the space. Fitted rudder springs mid-fuselage – tricky leaning through the luggage door. Assembled Rudder pedals assembled and clecoed in place for now. Centre console box. Throttle/brake quadrant. All seats assembled (more than >>500 rivets right there) . Front seats backs spray painted with 2K aerosol (RAL 7005 Matt). Lets see if it’s hard wearing enough. Booster pump – learnt about differnt NPT fittings and torquing them. Hand tight + 1.3 turns typically. Dry fit heater and tubes. Naca ducts and fresh air assembly clecoded. Challenging to fit factory assembled elevator rod, eventually did per assembly instructions. From rear with some force and grease through the mid-fuselage grommet! Some have said that the fresh air mixer rattles and doesn’t close completely, so as it’s easy to do at this stage I added some 2 mm craft foam as others have done. Glued down with Gorilla glue.
