I am using a 10A 5V BEC to run my receiver and APM. It connects to the 11v line on the PDB and the 5V connects to the battery port on the JR921 receiver. I power the APM via one of the receiver channels.What I want to add is a laser I know operates on 2 x 3V that use these batteries. http://www.szwholesale.com/ultrafire-tr15270600mah-batteryufcr2600-p-993.htmlI know I can power it with batteries but was preferring to do it from the BEC and will also control it via this:http://www.hansenhobbies.com/products/onboardacc/ners/Can I just connect this to the receiver that I want to turn it on/off with or is that too much amp draw? I calculate it to be 3.6W

Well more for the convenience of being able to turn it on/off from the radio. This plugged into the receiver will handle 1.2Amp load so should be ok since the batteries that power the laser are only 600mA.
