Panasonic 18650GA cells have a gravimetric density of 224 Wh/kg allowing some fixed wing drones to achieve 2+ hours of flight, these new SES cells claim 400-500 Wh/kg and are apparently available for sale now.
Could we see a 1 hour multirotor flight as normal…Continue
I wanted to do a few real world hover tests with different prop sizes to satisfy my curiosity.
I tested 3 sizes of some commonly used props, the RCTimer Carbon 10x4.7, 11x4.7 and 12x3.8, all carefully balanced. There are other very similar props branded differently.
The 'copter is a carbon Tricopter, battery used is a new Turnigy 3300mAh 30C 3 cell. The motors are…Continue

Went for our long distance flight attempt today, flew a test flight with a 6S 2600mAh LiPo and then put in the 18650 batteries in, the log unfortunately shows both flights as I forgot to reconnect so I have calculated the time and total distance from the launch of the second flight to the landing.
Basically we did a 300m diameter Loiter for most of the flight,…Continue
We tried some formation flying with 2 different APM equipped planes.
Both were loaded with AP v2.76 and the same exact mission except for the chase plane flying 20m higher than…Continue
Been testing a brushless gimbal on my quad, it's an own-design laser-cut Liteply gimbal which uses a Foxtech AIO (Martinez) controller ($50) and Foxtech 2208-70kv motors ($21). Information is a little hard to…Continue

Had a little fun flying in a local park here in Johannesburg, South Africa. Used a GoPro Hero on my own design anti-vibration mount and my quad running the newly released v2.5 firmware. Click on the photo to go to the youtube video.

Further to my informal testing of 3S and 4S batteries with the same prop I did a test with 9x5 3-blade props (http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=5248) and 11x4.7 2-blade props (APC SF 11x4.7).
I have an old BNB Digital Power recorder so I wanted to have a look at the hovering power requirements of my quad. The weight of the quad with either battery is very similar.

Some onboard video taken from my quadcopter in the Kalahari desert, South Africa, bordering the Kgalagadi Transfrontier Park. Sorry not GoPro quality and there's no sound.

A couple flights this morning using my trusty old ArduPilot Legacy & ArduIMU. Separate Mediatek GPS's on both AP and the Remzibi OSD. A Hobbyking 420 TVL camera provides the video sent back to the ground via a BOB Fox 700 1.2GHz transmitter. FPV is done with video goggles. Radio is a Hitec Aurora 9.
