Goal of this project was, to build a 3" HD fun flyer with balanced power to weight ratio.
Everything works fine exept the variable motor PWM of BLHeli 32... This sounds unhealthy, so I switched to fixed 48 kHz.
The quad is well (not perfect) tuned and it's really fun for freestyle flying and hitting small gaps.
Until now it's very robust and crashresistant - as you can see on the photos, this thing is in use ;)
For me the flight time is the Brownie point, with minimum 4:30 minutes and maximum >8 minutes on 4S 450 mAh.
3S is also possible and it's not that big difference, regarding power.
On the whole it's very suitable for everyday use!

There's not much special, but the mounting of the Vista. Here I removed the srews from the four edges, drilled through with a 2.1 mm drill and screwed alltogether with threaded rods from top to bottom. Perhaps the aluminum srews for the props (to reduce the rotating mass) and the motor mount are worth mentioning, but that's it...

Weight with props: 106 g
AUW with 4S 450 mAh: 157 g
AUW with 4S 550 mAh: 167 g
AUW with 4S 650 mAh: 183 g

AirbladeUAV has done it again and this time they've brought long range to the 5" class!

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..
