Right Wing Closeout & SB0014
With the trim servo mods completed, I spent the last few working sessions closing the starboard wing. There are many hundreds of rivets to install, and sometimes the holes need to be reamed open for fit, so it’s just time-consuming work. I also had to carry out service bulletin...
Aileron Trim and Wing Electronics Module
This past weekend I finished up most of the aileron trim servo installation. My remaining tasks were to glue down the doubler, and to install the connectors for the wire harness. Before gluing down the doubler, I decided to increase the number of screws holding the plate from 8...
Aileron Trim Servo
It’s been a little bit since my last logbook entry, but have some great news to share. I recently made an exciting career change — I accepted an offer to work for a startup company called Merlin Labs and I’m helping create an autonomous flight system for retrofitting into...
Right Tank Pressure Test OK
After replacing the one bad rivet on Wednesday and letting the sealant cure, I re-pressurized the tank on Sunday afternoon. 24 hours later, the pressure reading was exactly the same, so the tank is good. As before, the zero point for the unpressurized tank was 16” WC, so I...
Right Fuel Tank Closeout and Leak Test
Over the past few weekends I worked on closing out the right fuel tank. I attached the last accessory bits (fuel pickup, vent) and then proceeded with applying the sealant for the back channel/cover. Having the wing turned 90° definitely made it easier to set the fuel tank in...
Engine Transport Success
When I bought the engine way back in December 2020, I planned to bring my plane to the airport to install the engine. I found space inside a community hangar at the Nashua airport, which I where I will perform final assembly. The hangar manager graciously allowed me to...
Refueling Options
As I’ve been building my second fuel tank, another thought has re-entered my mind: how to get gas to my plane. Leaded gasoline has been in the news lately, with a not-so-great spotlight being shone on aviation’s 100LL AvGas as being the last major producer of airborne lead emissions....
Right Fuel Tank Accessories
I spent some time this weekend adding components to the right fuel tank in preparation for closing it up: the fuel level sender, drain fitting, and fuel cap. I also drilled out and replaced a few sealed rivets from the previous session of setting the ribs where some rivets...
Right Fuel Tank Build
It’s been over 2 years since I built the first fuel tank. The right side fuel tank skin arrived with a big dent when I originally received my wing kit, and it took a few tries and a lot of waiting to get a replacement skin. But, with everything...
Firewall Forward Kit Arrival
Last week I received the custom firewall kit I ordered to install the 915iS on my Sling 4. Shipping took a long time – almost 5 months – but I’ve read it’s a widespread issue in sea container shipping right now. Everything in the kit arrived just fine. I...
