yep when this one was built the 10a esc was the only 20x20mm 4in1 available and there were no micro cameras (hence it has mini). What's the funny thing - yes it absolutely runs on this 3S rated 10a ESC. Sunrise ESCs are just so bullet proof. They don't look fancy, they are no shiny stuff. But they just work. I use them quite a lot and never burned one (not that I haven't tried)

lastlast weekend I used this little guy ona a race against big heavy 5" quads. Zero technical problems.

looks awesome, i love 4 inch setups. i have a question though. Does this actually run those 4s batteries with 10amp escs? One of the other guys on rotorbuilds was using a 12 amp on his 4 inch 1407 setup and he ended up burning it up trying to escape a tree.

Haha yeah guys I know those prices are crazy. But the other stuff is quite cheap isn't it? LOL Just haven't figured it out where did it get those prices and how to change them. If anyone is kind enough and guide me I'd be glad

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..
