LDARC 450X – 118 gram FPV PLANE

I was wondering how small FPV plane can be build, and decided to check it. As a air frame I used LDARC 450X foam plane, which is very small, but big enough to mount FPV gear. And everything ready to flight (including 450mAh 2s lipo) weights only 118g 🙂

So, we have following stuff on the board:

  • 20x20mm HAKRC MiniF4 F4 Flight Controller – running arduplane which you have to compile by your self, cause binary version is not available now 😉
  • BN-180 GPS
  • QCZEK LRS 868MHz 100mW with FrSky 868MHz antenna
  • 6A Turnigy ESC
  • 2x Blue Arrow High Speed Digital MG Micro Servo 20T 0.5kg / .06sec / 3g from hobbyking
  • Multistar V-Spec 1104-3600KV Multi-Rotor Motor (CW) from hobbyking, with LDARC stock propeller.
  • Gaoneng 450mAh HV 7.6V 80C 2S1P
  • Eachine VTX03 with camera from broken Eachine TX01

And to be honest, it flies amazing, I’m really happy with this little wing, which acts as a much bigger plane. It’s easy to lunch and 6km total distance on 450mAh little 2s battery is quite impressive.

Take a look…

Video quality is not the best, but telemetry make possible even longer missions without video. I would try next time how it works ;). Anyway you can always use telemetry data to visualize your journey.

And some more pictures of my tiny FPV wing.

And arduplane settings, you asked 🙂 http://qczek.beyondrc.com/wp-content/uploads/2019/08/ldarc450_arduplane_setup.zip

  1. Impressive micro build !
    Which board parameter do you use for build configuration ? Do you create a custom target? I’m interested in, cause i have an F4 mini on inav, and i want to migrate it on arduplane. Have a nice day

  2. Fantastic! It is possible compile fw also for arducopter? I have the some board on 90mm quad and betaflight and I want to try with arducopter. Thanks
