| New plane! |
Introduction
I decided to try something different and having never gone down the Bixler style road, the Strix StratoSurfer seemed like a good place to start. Also, after reading much about this plane, I decided to start with a larger motor/prop combo. For flight management/control I'll be starting with an Omnibus F3Pro flight controller to keep it light and simple.
Here then is a collection of my build notes and eventually a flight review of this plane.

Components/Flight Gear
Below is the layout of my selected components:
|
Power Set-up
For power on this build I have chosen the Sunnysky X2216-1250kv. For an ESC, I am using a HobbyKing Blue Series 40A with extra Low ESR capacitors added. At some point I will replace the Blue Series ESC with a Hobbywing Flyfun v5 40A unit to get active freewheeling.
- Motor - Sunnysky 2216-1250kv
- ESC - Blue Series 40A
- Prop - Aeronaut Cam Carbon Folder, 8x7
- For more informaion on setting up a pusher folding prop - How To - Set-Up a Pusher Style Folding Prop
- Battery - Multistar 4S/5200, 10C or a 4S/7000 Li-Ion
|
| Mounted with a 7x6 Aeronaut folder |
|
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.

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

- w/iNav 1.8.1
|
| All wired up! |
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.

| FC mount |
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.The printed part is glued in with contact cement but you could also use E6000 or UHU-POR.

| RX mount |
|
| DragonLink UHF antenna |
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.
|
FPV Gear
For an initial setup I am using the stock foam cowl pieces with simple mounts for the FPV camera, VTx and HD camera. Here are the initial components:
- VTx - RMRC 800mw, 1.3G
- FPV Camera - HS1184 with 2.8 lens
- HD Camera - Mobius Mini
Airframe
Stabilizers
On the tail linkage I used the stock linkage bits with Hextronic MG14 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.
Fuselage
The beauty of a plastic fuselage is it is already very durable. Because of where I fly (and land) I still felt I needed a little more protection on the nose and rear skid so I designed up a couple of skids which conform to the fuselage shape. The new nose skid also has a provision for a bolt-on tow hook which I will add later. These are printed in ABS at 80% infil for durability. For glue, I used E6000 which is similar to UHU-POR and Beacons FoamTac.
