Castle Creations CC BEC Pro 20A 12S Switching Regulator

Great product for bigger RC planes, programmable piece of mind to take the stress off your ESC. Lots of power to spare even on my Corsair with 13 servos

Put this in my black horse viper xl to run hv servos, and power the retract controller since it had 2 leads. Wired directly to esc 12s power never faultered! Still going strong never gets hot, would recommend this to anyone that needs an adjustable bec( castle link sold separately)

This is a fine BEC from a respected American company. It puts out a large amount of current and in my 550-size heli this unit hardly even breaks a sweat. You can set the voltage using the Castle Link. If you buy a Castle speed controller there is usually a coupon for a free one. An important point is that you must disconnect the Link if you are trying to measure the output voltage you have set. If you leave it connected while bench testing you will only measure about 4 volts on the output. This is true no matter what voltage you select. This is not a real problem, just something to be aware of to avoid going around in circles while setting things up. Castle really should mention this in their documentation or their web site.

Works fine. You will probably need the programmer as well, which is another $30-$40. This should probably be sold in combination with the programmer, as a combined deal.

As advertised top-notch item
