Finally my RC plane hobby reached the point where the stuff start feel like final as on my drone side.
The small sub250g plane is awesome Nano Goblin, but I want some plane that I could fill with any stuff I want. After all big wings and planes Volantex Ranger 2000 shows me that this is it

Here you'll fing my solutions to get parts in. STLs of 3D printed files are listed below.

I use Matek F765-wing FC that has been in many previous planes and now ended up in this Ranger. It has plenty of ports and pwm outs. I like it.
FC is mounted on top deck. FC has two camera switch, but I have three. So I added separate 3-cam PWM-switch nearby.

Main camera on the front bottom is Foxeer Razer. I made a holder that has welded nut, for easy mount.
Step file is provided, so you can tinker it to suite your needs.

Tail camera is cheap nano camera from Banggood by Kinkkong.

Gimbal camera is Runcam Micro Eagle. Servos are analog metal gear 9g. Previously I used lighter and digital servos. But digital servos are not smooth and center point is glitching. Metal gears ensure longivity in harsh usage.

Switching schema:

  • FC cam 1: main camera
  • FC cam 2: cam switch
    • Cam switch 1: Tail camera
    • Cam switch 2: Gimbal camera
    • Cam switch 3: spare

On radio I have 3-way switch.

  • Pos 1: main camera
  • Pos 2: tail camera
  • Pos 3: gimbal camera
    • OpenTX: Throttle on hold with last value and throttle stick sends data on ch11.
    • iNav: Rudder centered. Yaw controls pan servo. Ch11 controls tilt servo.

On mode2 you can maneur plane with right roll/pitch stick on throttle's last value and use left yaw/throttle stick to controll gimbal.
Maybe in the future I'll try to find head tracker module.

This time I wanted to keep electronics in fuselage. So the only place for VTX antenna is above the battery. Then the antenna will be seen in mid and long range all around. Only when flying straigt above the battery would cover it and there is any ways null point in anenna too. I soldered 90 degree SMA plug to Tramp HV and mounted on a side of the fuselage. TrueRC's long version of the superb Singularity antenna stays ideally above the battery.

On previous planes I had a hinged mast for TBS immortal antenna on top of the fuselage. This time I wanted to keep fuselages top part clean for mounting additional HD cameras like GoPro. Also fixed mounting onto the detacheable wing is also out of the question. Then I got an idea for quick clipping antenna on the wings leading edge with TPU holders. Crossfire nano itself is mounted inside the fuselage.

First idea was to place it inside the fuselage with provided foam part. But then I realized, that I want to put HD camera on top of the fuselage in CoG. All modern HD cameras block GPS signals just by being nearby. So gps module should go somewhere else. Tail boom. Perfect place and awesome amount of the satellites found.

Changed motor to to a bit lower KV than stock for efficient use with 4S battery.

Emergency beeper
I use emergency beeper that act as a normal beeper. But when battery is detached or dries on crash beeper starts beeping with its own battery.
Beeper is mounted on the front.

RGB lights
Winter is coming. So comes the darkness. I've added 12V RGB LED strips into the body and the wings. I can power them with separate 3S battery and control colors with remote control. Removed led controller from its case and mounted on the bottom ov the fuselage below the battery deck.

Inserted 1x3mm CF stripes into the wings leading edges to strengthen them from possible hits while landings.
Found awesome plane bag for storing and carying around.

Future additions
Pitot tube for air speed.
APC propeller.

AUW with 4S 4Ah battery is 2kg.

Is your ground station setup for auto tracking? Asking as I'm really wanting to build one that tracks.

DiAleksi   Oct 23, 2021 

Nope, manual tracking. I'm giving up with LR flying, as nowadays rules prohibits that. And flying mid range doesn't require much directing as patch antenna takes wide angle area nicely.

what is the reasoning behind having 3 cameras if you have the insta 360?

DiAleksi   Sep 11, 2021 

You don't fly FPV with insta360. Insta is just for HD recording.

ORFilms   Oct 12, 2021 

i get that, but why do you need 3 fpv cameras?

DiAleksi   Oct 12, 2021 

When you cruising around for long time and long distances, it's nice to change the view.
Fixed main camera is just fixed main camera.
Rear camera for overall view with a plane in the front. Like 3rd person view.
Gimbal camera on the lid allows you to look around without moving the plane itself. Why it's not a main camera, because it's detacheable and it doesn't have clear view in the front, as plane's nose is shown at the bottom of the video.

Could you share your inav config?

phaley51   Aug 17, 2021  

Awesome, I've been wanting to get into the plane game but haven't just yet. Looking at the AR wing Pro but part of me wants to do some sort of EDF conversion even though I know its not practical from an efficiency/weight standpoint. Do you have videos of this on your youtube channel?

DiAleksi   Aug 17, 2021 

Yesterday was its maiden. It was awesome. Waiting for better weather and time to fly again and shoot better dvrs from all three cameras.
On instagram I'm showing an example how camera switching works

But yes, when I get to fly on it again, I'll definately make a video of it. Also with 360° camera.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
