2nd quadcopter practically RTF...

Other than having the recently ordered flight control board (Multiwii SE) mounted and configured, everything else was completed today with the addition of the custom made landing gear:

Brushless gimbal almost complete

With the arrival of the Mobius action camera, which is a Full HD (1920x1080 @ 30 Hz) little animal (very nice video quality for the price), my aerial filming addition to my #1 quadcopter is almost complete. The only missing element is the gimbal controller board, which I have ordered through ebay, but my mistake (or not) the seller have sent the MPU6050 instead (which I had at the same time ordered from a different seller). Result: I have two MPU6050 gimbal sensors and no gimbal controller. As such a dispute is being solved, and the seller decided to (supposedly) ship me the controller board. Otherwise I will escalate to ebay, get refunded, and the seller downgraded (or banned, who knows..).

Improved quadcopter - more "avionics" and increased run time

In the several weeks that followed a crash caused by an ESC failure, plenty of work have taken place (some of which documented here). Several things have been done since:

• Replacement of the ESCs with a 30 Amp quad ESC;
• Upgrade of the flight controller firmware;
• Building and programming the PPM Sum encoder;
• Building a BEC/filter with 12 V and 5 V outputs;
• Adding landing gear;
• Adding voltage and current sensor;
• OSD firmware upgrade;
• Change of LiPO battery from 11.1 V (3S) to 14.8 V (4S);
