Here's my latest whoop build for this season.

Specs

  • Meteor Air 2 Frame
  • Betafpv AIO Air 5-in-1 FC
  • 0702 Topspin Firefly 36,000 KV Tiny Whoop Motors
  • Runcam Nano 3 (the good old one!)
  • Peek Screws
  • Mylipo 305 mAh battery
    Weight: 14.87 g (+0.05 g foam sheet as protection between camera and FC)

A little beast — and almost retro with the Runcam Nano 3, right?

The Runcam Nano 3 was, all things considered, one of my favorite analog FPV cameras. Great FOV, beautiful colors, solid contrast.
It wasn’t the best in low light, but it was extremely light and durable.
Things changed around mid-2020 during the chip crisis.Runcam started using different image sensors, and the result?
The Nano 3 basically became unusable.
Over the last few weeks, I managed to stock up on some of the good old Nano 3 units — the ones you can recognize by the printed "Runcam" lettering on the back under the sticker.
In my opinion, the old Nano 3 is still a top choice today.

Canopy and frame

The canopy is the classic TPU mount with cutouts. It took a few attempts to get colors matching, since it's printed using three different filaments.
I choosed red for these struts to match with propellers and in my opinion it looks sick.Weight is 0.68 g.
The frame is modified slightly. Still durable. But removed one strut / duct for weight saving and improved airflow. Short battery cable 22awg, slightly cutted Bt2.0 plug. Enamelled wire for motors and cam.

⚡ Motor Highlight

The highlight of this build are Topspin Fireflies 0702 36,000 KV motors from Tinywhoop. Unbelievable response, tons of thrust, and still extremely lightweight.
Huge thanks to @tinywhoop — these things are wild.

This whoop is an absolute blast and realy fun to fly.

Thanks to rc-hangar, tinywhoop and mylipo for support !
