RE: HV servos with stock RX??
drube if you would click on the technical info for that servo it states at stall it will pull 5amp. Now you put two of those into a heavy load and you are reaching 10 amp, now add one more and you have exceeded most standard Rx's load capability. I am not saying it will not work, many people do it without a thought. I am just saying I see many issues in my club where it is a simple overload taking place. The overload does not have to be enough to short or shut the Rx down but it can and often will create other issues. Issues such as buzzing servos, eratic surface movement, accelerated battery consumption, momentary loss of signal. Like I said above, that little gadget from Radio Shack, 2 of them is ten buck's, and there will never be an issue. I personally like taking to the air with the best odds of a safe return.
