it’s time to fit the wings so I need to add the connectors to the trim, landing lights and heated pitot looms that I have already run in. I’ve also run in the radio coax cable so need to terminate that and carry out a final tidying up of the wiring.

As mentioned before I decided to use superseal connectors as they are failproof and waterproof. I’d already completed quite a few of the connections but was distracted by another job. Whenever I’m distracted I always document what still needs to be done in my project plan.
With all the connectors added the next job is to add an Amphenol to the end of the coax cable. It’s quite a complicated connector so I needed to test i on a cut off first. Once cut and trimmed the connector is soldered on to ensure a good connection.
The finished connector, fairly straightforward but just needed to be thought about before committing,
Now time to fit the wings so I can set all the ailerons, check the pitot, trim, flap, strobe and landing light circuits are working as wired. Ian and Peter Sharpe have offered to help and as usual Ian wears his designer gloves for the wing lift process. He looks quite fetching 🙂
Peter Sharpe at the ‘sharp’ end adding invaluable assistance.
Once the wings are attached the main bolts need to be tapped home with a small nylon mallet before the nuts are added.
With the wings added she’s a tight fit in the hanger with just 6″ between the front door and rear wall. If I had fitted the prop she wouldn’t fit!
Now all the wiring has been completed and checked I can start to tidy th wiring. Ovrall I’m quite pleased with the results. Circuit Breakers…
…Bus Bars…
…Equipment trays and connectors…
… and switches. All look a lot tidier now.
She’s coming along nicely now and it won’t be long before I can start engine tests…

A lot to do today, as every day! When the delivery arrived I found that some of what I had ordered was out of stock. It’s not a big problem as there are lots of other jobs to do. So I’ll wire up the power side of the system and label, install and test the radio and transponder coax cable.

Time to wire up the power side of the electrical system. I’m reusing the wire that I have leftover from the other circuit wires that were trimmed back. There’s plenty to do the job although not a unified colour as long as they are labelled it will be ok.
My new friend. A Dymo Label Manager 200 that I bought some years ago. It’s been invaluable and luckily I managed to get some label cartridges.
The +ve bus with 11 of the circuits completed.
The circuit breakers connected, some tidying will be required but it’s mostly complete.
The complete panel powered up for the first time. The system shows a 7 amp power drain which is roughly what I had calculated.
My DPD delivery was a day late but got delivered at 10am so I could get on with the wiring of the Transponder and Radio with the coax.
The radio coax cable runs through conduit in the fuselage and is terminated with a TNC connector that I’ll do tomorrow.
With all the cables protected with sleeving or conduit and secured in place I can fit the interior trim.
The rear of the cabin. I’ve checked the radio/headset loom and it works fine so I need to mount the LEMO headset connectors and then I can fix the interior panels.
Right side of engine. All the sensors are connected except the Tachometer, soft start module, magneto wires.
Left side of engine.
Looks a bit busy but with a bit od tidying it will look a bit neater. Quite pleased with the progress so far.
