Ultra Capacitor for APM power security and VCC stabilizing

Started this discussion. Last reply by Veikko Vierola Apr 16. 3 Replies

Hi, I just tested to put three 5,5V 1.5F ultracapacitors parallel and connected the system to the APM power rail. APM stayed alive 10 seconds when normal LIPO/ESC was disconnected. Telemetry radio…Continue

Radio Fail safe function works only in "manual modes"

Started Feb 10 0 Replies

Why does throttle failsafe work only when you are in MAN, STAB, FBW A/B modes. If you are in any NAV-mode like AUTO or Guided the throttle fail safe or RTL will not activate. Why is this like this?…Continue

0° angle of incidence and arduplane code.

Started Feb 4 0 Replies

Hi,Is the arduplane code build so that as default the plane should have few degrees positive angle of incidence on the wings. Is there a pid that can be adjusted if the angle is 0° or the APM is…Continue

"I think the voltage goes slowly up in the graph cause the capacitor is charging up slowly and it will eventually maintain steady 5,0V level."

Ultra Capacitor for APM power security and VCC stabilizing

Hi, I just tested to put three 5,5V 1.5F ultracapacitors parallel and connected the system to the APM power rail. APM stayed alive 10 seconds when normal LIPO/ESC was disconnected. Telemetry radio was also connected to the APM and transmitting full power.During normal LIPO battery usage the VCC looked very steady even if I made some heavy servo and ESC throttle movements every 10 seconds for 5 seconds each time. The capacitor system weights 14 grams and it is not much bigger than a five cent…See More

Dual APM UAV

Posted on June 20, 2012 at 2:20pm 40 Comments

I was thinking about an idea of a redundant UAV with 2 x APMs, 2 x RXs, Dual Servos/surfaces, 2 x ESCs and 2 x motors. The plane should be designed so that it could fly with only one motor if needed.

The idea of functionality:

  • If something in APM(A) network fails or works…

Hi Veikko,

The camera used was a Canon 5D MarkII 21Mp 14 second exposure at iso 3200.
