Indoor Mini Owl

Tired of replacing brushed motors, build the ultimate durable indoor QuadCopter. Irony is that it's so powerful than I spend more time outdoors with it.

Originally I was going to use the PicoBLX Stack with Inova VTX (Clone, not original). I ended up frying my entire stack . So now am trying the Eachine Omnibus F3 and the Eachine ATX03.

Have a test video. No VTX hardware installed when this was taken. Quad can pull a RunCam 2 no problem.

I used the DYS 7000KV Motors with 2s. More than enough power.
Originally I had FuriosFPV Props, they were garbage, the new GemFan ones are far better.
The flight controllers build in BEC is not powerful enough to drive the XSR, camera and ATX03, so I had to use an external BEC for the VTX + Camera. The FC is also very susceptible to vibration so I had to use rubber o-rings to dampen them.

Any updates?

Hello How much autonomy do you have in flight?

tracer   Nov 13, 2017 

None. This Flight Controller (and all micro flight controllers) lacks a GPS, compass and barometer. It would weigh more and consume more power (shorter flight time) if it did.

How do you like the FC? Are there any issues you ran to?

I have yet to get this into the air. I fried my XM receiver last night. This is my first Quad build (though I've been into RC for decades). I'll report back when I've had some air time with it.

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..
