My previous build was 4" Bangon and after few tweeks it seems great, but I like to try something smaller. Plan was to include propeller guards and 2s for indoor use, but mainly designed for small outdoor spaces.

With maiden fligt done I can say that it was under powered until I removed propeller guards and select light 2s battery (31g). With 3s it can handle propeller guards and 54g battery quite nicely. Well, nice park flier, but not for indoors. If I burn these motors (Racerstar Racing Edition BR1103B 8000KV 1-3S) , I will propably get something little more powerful.

ps. At cheap Flight Controller ( MAMBA F405 Mini) all cables must be soldered, no connectors. With my skills result is ugly cable mess :-)

UPDATE:
Ok. I burned motor almost immediately. And at same time I burned 4in1 ESC from other build. I dismatled this one and used this flight stack to other build. When I finally got new motors (MAMBA 1105 5500KV 2-4S), I rebuilt this with new fight stack ( LDARC/Kingkong KK12 KK Flytower), new motors and different camera. Part list updated and some new pictures added. Build is now much nicer (not so much ugly soldering). I will report how it flies ;-)
