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.

General Specifications

Distributor - BangGood USA
Aircraft - X-UAV Mini Talon
Build Date - April 2017

Flight Gear

The following are some 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.

• Motor - Sunnysky 2216-1250kv
• ESC - Blue Series 40A
• Prop - Aeronaut Cam Carbon Folder, 8x7

• Battery - Multistar 4S/5200, 10C or a 4S/7000 Li-Ion
  
  

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

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.

RX 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.
