| New plane! |
Introduction
Decided to try something different and having never gone down the Bixler road, this seemed like a good place to start. After reading much about this plane, I decided to start with a larger motor/prop combo. I also decided to try an Omnibus F3Pro flight controller to keep it light and simple.

The following are some of my selected components with links to some of my favorite vendors.

Motor Mount
For the motor mount I designed and printed one that spaces the motor 6mm rearward and 19mm above the original mount to get the clearance needed for 7" & 8" props. Additionally, I printed a cowl to protect the motor and direct cooling air to the rear of the motor.

ESC Mount
I decided to design and print a simple mount to hold the ESC. It mounts with four M3x6mm nylon screws and a wire tie to hold the ESC. This print is sized for a 25mm wide ESC.

Flight Control
For flight control I have chosen the Omnibus F3Pro from Banggood. It is very inexpensive and in my experience completely reliable.

FC Mount
To mount the FC I drilled out the existing mount holes to 2.3mm then tapped them to M3 and flooded the tapped holes with thin CA. This makes them more than strong enough for a set of rubber M3x6mm stand-offs.

RC Control
For radio gear I am using my standard DragonLink V2 system. I have mounted the DL dipole inside the verticle stabilizer. The RX is mounted on a printed deck below the GPS mount.

GPS Mount
For the GPS I printed a mount plate to replace the white plate on the rear of the fuse. This is sized for a Ublox Mini M7 GPS.

Video Downlink
For the video downlink I am using an RMRC 1.2/1.3G VTx with a DragonLink video dipole. I will either run 400 or 800mw depending on where and how I am flying. For an FPV camera I have selected a Fatshark V2 700tvl unit because of its size and decent performance.
Airframe Build and Assembly
Stabilizers
On the tail linkage I used the stock linkage bits with metal gear digital servos.

Wings
Nothing new or special here. I added 1" (25mm) of 3 mil laminate to the leading edge. Linkage is the same as the elevators and servos are Corona DS929MG's.
