I decided to install Dynon products in the Kitfox. For the last couple of months I have been working with Advanced Flight Systems in Canby Oregon designing a VFR panel and putting together all of the needed components.
I picked up my early components which included the auto pilot servos. The idea is to get everything installed in the aft part of the fuselage so that the covering can be completed. The wiring for the horizontal stabilizer and trim sensor wire have been run.
Shown above is the elevator auto pilot servo being fitted. Below is a pic the mounting bracket that I fabricated from some aluminum angle. It is bonded to the frame and the linkage is fitted
Above shows the servo bracket painted and servo plus wire harness installed using DB9 connectors.
Below is a pic of the other side.
It’s a little hard to see but the aluminum triangle frame is for the ADAHRS to be mounted to. Because the baggage area was extended I will need to install a remote magnetometer in the left wing tip. Normally there is a location just behind the standard baggage sack to mount the ADAHRS.
Below shows the position of the ADAHRS. It is mounted dead level with the fusalage floor. A static port and the pitot tube are connected here.
Here are a couple of views of the roll auto pilot servo. It is mounted and wired in.
Another item to be installed is the ELT (emergency locator transmitter). It’s a little hard to see but Kitfox has an antenna mount for the ELT.
About two weeks ago I picked up the completed system. This is going to be “plug and play” for the most part. It was nice to see the entire system up and running. All of the harnesses are made and tested by the AFS team. I can not say enough about how good it is to work with AFS. They also have great technical support.
Here it is temporarily mounted. I will be painting the panel before installing of course. There are a few empty holes. The ones on the left and right are cabin vents. The round one in the middle is for the Air Master prop controller.
The pic above and the one below shows some of the work that AFS did for me. I temporarily hooked everything up just to get an idea of how the components would need to be arranged give the cable lengths and space available.
All of what you see in the two pictures above has been removed so that I can continue with the covering process.
Now that all of the fabric work and painting is complete it’s time to move into Firewall Forward and avionics. See the FWF section for everything forward and this section for all avionics related topics.
Below are a few pics of the ECU. It is not located where the factory does but it makes sense to me and frees up space on the right avionics tray.
I moved the heater core aft enough for the ECU to be mounted on the back side of the firewall. It is spaced away from the firewall about a half inch to allow good airflow and room for some wiring to pass through.
Next is to get the panel installed but I wanted to get a glove box installed if there was room. A good friend and fellow Kitfox enthusiast, Doug Pflugradt, gave me a Vans aircraft glove box that he didn’t have a use for. It was shortened to 8 1/2” and was the perfect size. Below are a few pics of the glove box install and panel painting. I used Rustoleum “Hammered” gray and took most of shine off with scotch bright.
I gave the paint about four days to cure and installed the components. I was really looking forward to this.
And now for the labeling. My wonderful daughter, Hannah, has an electronic cutting machine that she used to make all of the labels. I’m very pleased with the outcome.
And here it is installed.
All of my instrumentation is Dynon supplied by Advanced Flight Systems. I had AFS make up almost all of the cables also. Below are a few pics behind the panel. It looks a little chaotic right now but will be tied off after everything is routed. Every cable or wire is labeled for future reference.
I still have the EMS to complete, and a few odds and ends. Not shown are the transponder antenna, com antenna, ADSB antenna or the GPS antenna. I’ll get pics of those for next time.
I did get the head phone jacks installed. I put them in the baggage area by the headset pockets. I put the pilot jacks on the co-pilot side and the co-pilot jacks on the pilot side so that they are easy to reach inflight if necessary. Below is a pic or two and notice the triangle windows are installed too. I bought 1/8” tinted polycarbonate to match the rest of the “glass”.
I also installed the OAT probe in the left triangle window. Easiest place to locate it out of direct light and a short run to the ADHARS.
Next up is to wire in the cab heater fans then move on to mounting the battery, solenoids and wiring that part up. “Back to work”.
I’ve pretty much finished with the wiring. I still have to check out and tie off everything behind the panel. Forward of the firewall the Kavlico fuel pressure valve and the fuel flow transducer need to be wired but I will wait until the fuel pumps are installed.
Below is a pic of the mass of harnesses behind the panel and a look at the Ray Allen G405 grips. I used shrink tube on the control rods rather than paint.
The G405’s have a PTT, trim up, trim down, auto pilot disconnect/connect, and a spare switch, hummm possibly a smoke system in the future?
