Picolongrange - tiny 3d printed FPV drone

Hi guys,

after Nanolongrange comes Picolongrange! This is my take on a tiny FPV drone with good range. It is based on a 3d printed 70mm frame and small 1.6" propellers. It features

  • 45g AUW
  • 500m range
  • 2km distance
  • GPS

Moreover, it is a rather simple build with only the GPS required to be soldered. However, you will need some basic knowledge on FPV drones/ Betaflight to complete this Instructable successfully.

3d Printing the Frame

  • Download the .stl files from Thingiverse.
  • My slicer settings are 0.2 resolution and 20% infill.
  • I strongly recommend using ABS or ABS+ to get a rigid and temperature proof frame.

  • Mount all 4 motors on the frame using M1.4 3mm screws. One side of the frame has countersunk holes where the screw head is supposed to fit in.
  • Use M2 10mm screws to mount the AIO flight controller. The back screw needs to go top down to hold the GPS mount.
  • Solder the GPS to the flight controller. Use a free UART and solder RX to TX and vice versa.
  • Mount the canopy on the frame. Use a M2 plastic screw in the front and a rubber band on the side screws. The rubber band will also hold the battery.

  • Connect to Betaflight and make sure the board is correctly aligned, the RC link set up and motors spin in correct direction. If you are a novice you will find plenty of information on the internet. Joshua Bardwells tutorials on Youtube might be very helpful.
  • For best longrange experience set the VTX to the highest output level. However, make sure to comply with your local regulations.
  • Enable GPS on the UART used. For me, in Config NMEA works.

I went 500m but I' m sure with a newer AIO board featuring a 400mW VTX 1km range should be no problem. Stay tuned!
