Introduction:
This is the plane I am working on now which has plenty of room for FPV and long flight times.
I got it from HobbyKing:
https://hobbyking.com/en_us/2m-pusher-glider-pnf.html
The Ranger 2000 is easy to assemble and features a large wingspan for stability in the air. The wings are fitted with two spars to strengthen the wings and they are attached using fast connecting wing clips to join the wings into the fuselage. After flying, simply squeeze the clips to release the wings and easily store the plane in your car.
You can also buy the Volantex version which is the same but with different decals
It's the Volantex Ranger 2000 V757-8 2000mm Wingspan EPO FPV Aircraft RC Airplane PNP and you can get it from Banggood or other vendors:https://www.banggood.com/Volantex-Ranger-2000-V757-8-2000mm-Wingspan-EPO-FPV-Aircraft-RC-Airplane-PNP-p-1151700.html
The fuselage has the capacity for an FPV camera and related components. The plug-and-fly plane is a single-body aircraft with a plastic fuselage that offers flexible, lightweight protection in case of crash landings. At the front of the fuselage, a pre-cut hole gives you the option of adding an FPV camera. The position puts you right in the pilot's seat without having to cut into the sturdy body of the plane yourself. Remove the black canopy to reveal a flat bed for mounting different cameras, transforming your glider into the perfect FPV model or videography vehicle.
Features:
• PNF single-body aircraft
• Optional FPV camera mounting
• Click & Plug wing clips to fast assembly
• Removable canopy for mounting different cameras

Parts and Modifications:
Box Contents
The stock servos were replaced with Emax ES08MA II 12g Metal Gear Servos for more durability and smoother control. These can be purchased in many places but I got them from a local outfit called StoneBlueAirlines or GetFPV.

Laminating Film
I am using a PixHawk Lite V2.4.6 32bit for the Flight Controller with accompanying MinimOSD board. The GPS is a Neo-M8N GPS GLONASS w-Compass.
I didn't use the compass since it's a plane. I purchased the PixHawk Lite from GoodLuckBuy and GPS came from Banggood. See below.
See this video for MinimOSD Setup with Config Tool and FTDI USB Adapter, EZUHF Setup.

PixHawk Lite
GPS from Banggood
Compass not recommended for planes just GPS.
See note in this link:
"Note:
Compasses should always be enabled for Copter/Rover, but may be disabled (not recommended) for Plane."
"Enable compasses: determines whether whether (any) compasses are enabled. If enabled the flight controller will use the primary compass for heading data, otherwise the heading will be estimated from GPS. Enabling the checkbox corresponds to setting parameter MAG_ENABLE=1."
Won't Arm, Servos not working fix:
On the pixhawk sometimes it won't arm on the bench unless there are no errors. The servos won't work etc unless you disable the pre-arm checks.
Here is how:
Mission Planner Config/Tune:
- Standard Params List
Set all Arm Checks = off
- Full Params List
BRD_SafetyEnable = 0
Wiring: In this section I have the wiring layout, wiring diagrams and videos explaining how to connect the electronic components and install the PixHawk Lite on the Ranger 2000 tray.
PixHawk Lite FPV Plane Wiring
MinimOSD Wiring and Prep:
By soldering the jumper on top and bottom of MinimOSD you can run both stages via the 5 volts dc.
You must however cut the etch to the 12 volt pins if you plan on using them so the 12vdc doesn't conflict with the 5vdc. See link below

Stabilizer Control Surface Setup and Hardware Failsafe Setup on PixHawk
I replaced the stock 1400kv motor with this
SunnySky X2216 KV1250 II Brushless Motor for use with a 4s Lipo batter.
Using a 4s LiPo Battery 3000-4000 mah. The power module for the Mini Pix Hawk Lite is in the picture above the batteries which measures voltage, current, and provides 5 volts dc to Pix Hawk.
For the video transmitter I wanted to use a Lawmate T1013 Eagle 1.3GHz VTX
but it interfered with the GPS sat reception so badly that I switched to a Digital brand 400mw VTX
Lawmate T1013 Eagle 500mw/1000mw VTX
Digital brand 400mw VTX
VTX Antenna: I will be using one of these two dipoles for the 1.3GHz video.
For RC Control I will be using a 433MHz EZUHF LRS receiver like those shown below.
I have include the setup links below to help you get everything configured such as Flight Modes, Failsafe, RSSI, EZUHF and MinimOSD:

A UHF Dipole Antenna for the EZUHF Receiver will provide better reception than the stock mono pole antenna however the dipole antenna (show below) dangled below the fuselage so I decided to use the stock antenna (shown above).
