I'm starting to build my Arducopter and immediately after having gone through the tests I could do with Mission Planner and a USB only I started looking for a solution on how to avoid recharging LiPo batteries every 10 minutes of testing, a especially how to avoid spending money on replacing AA stilo batteries just for testing the radio.
So I came with the idea of using my bench power supply for powering both the Arducopter and the radio. I basically created 2 power cables, one that goes into the battery socket and one that goes into the radio power plug: on one side the respective plugs and sockets (a JST connector for the radio and a XT60 connector for the battery) and on the other side two banana plugs that go into the power supply.
I doubt I'm the first using this approach for testing, but I don't recall seeing it anywhere, so I thought it was worth posting it.
Here more pictures of the setup.

I'm documenting my build process on my Drone and ROV related blog, so if you are interested you can also have a look at it to see how I am progressing.
Comment by Norman Sanchez on December 14, 2012 at 4:41pm I use a power source for security cameras 20 amp 275 watt, this method to calibrate and test the quad is a source of economic and 6 amp 12 volt for the radio is very good. with a 12 gauge wire two pairs of 2.30 meters long I can last for 24 hours at half throttle and 16amp with 8 engines.

Comment by Simone Chiaretta on December 16, 2012 at 3:58pm Yeah, I know, have to find some first :)
Thank you

Comment by Simone Chiaretta on December 17, 2012 at 12:45am Ibrahim, the best solution is to buy a ready made kit, like jDrones or the 3DR kits. It cost less and it's less time consuming than buying all the pieces separately. The links to buy them are in the menu of the site.
Comment by Andrew McKinstry on January 4, 2013 at 2:54pm how many amps and volts are you setting bench power supply at?
