Upgrade my old LTKR120 for motor and flight controller.
I use 1304 4000KV mortor and 2 inch 5 blade props. It's almost silent for 3S 850mah, but uses 50% throttle for hover.
If choosing 3 inch prop, battery can use 4S 18650 3500mah for flying long range or use 4S 1000mah for racing.
Update:
The prop noise
3" > 2" > 2.5"
So current 2.5" prop is the most quiet and uses 38% throttle for hover(3S 850mah).
Update:
Upgrade to bigger 19mm camera, so the frame need to increase height to 20mm
Therefore, the props need to decrease to 2.4"

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..
Read moreWith 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.
