3inch 1404

As i got myself a set of DJI FPV Goggles i needed a small quad to test the new HD system. I had some 1404 Motors and a Whoop style Board lying around, so i cut a slightly modified 3„ Sanchez frame and printed a nice TPU canopy found on thingiverse.

A 2nd backup frame has been build with other parts i had around: Flightcontroller: Crazybee F4 PRO V3.0, Motors: 4x RCX H1304 5000KV.

3 Others for friend of mine have been build using either the JHEMCU GHF13 AIO or the JHEMCU GHF411AIO Pro. They are all running the Happymodel EX1404 4800KV motors with GemFan 3016 props.
