Trouble with a hex voltage

Posted by Graham Pollock on February 25, 2014 at 4:18pm

Hi I'm trying to find out the amp draw for my hexacopter to find out if i can put a 40 amp voltage telemetry monitor in my hexacopter

Here is my setup:

550 frame

3d Robotics 880kv motors

10x4.7 props

3d Robotics 20 amp esc's

5000 mah 3 cell battery with 30C rating

Here is the Meter i want to use http://www.alofthobbies.com/sp-40a.html

Hi Graham,

It is obvious that with such a motor configuration 40 amps is too low.

According to eCalc (http://www.ecalc.ch/xcoptercalc.php?ecalc) you would consume 65 amps at full throttle (assuming your AUW weight is about 4000g).

Just take a 90a attopilot or the 3DR PM module and you will be fine.

Check this out for battery/ power related calculations, you should get information on power draw and how to compute it correctly.

Good luck!

Will a multimeter work?
