They are hobbyking branded but since they are flysky based the bind right up to the Axial remote. I’ve bought replacement receivers in the event that the high voltage would burn out my original (wich never did). I’ve been running a 220 ounce/inch servo for 6 months and lately a Savox 444 ounce/inch brushless servo for the last 2 months. But I have been running my original AR-3 RTR receiver at 7.4V off of a CCBEC for 8 months and haven’t had a problem. So this would make the AR-3 operating voltage from 4.5V to 6.0V. The Axial AR-3 is based on a flysky receiver, so I assume that they have the same specs as the original GT3B receiver Fly Sky FS-GR3E 2.4GHz Automatic Frequency Hopping Digital System 3 Channel Receiver Does anybody know what voltages you can run the stock receiver on? Maybe I'm just not looking hard enough, but I can't seem to find any tech specs on them. If I run this setup, would my stock internal BEC running at 5V conflict with the servo running at 7.2+V?Īlso, does the voltage bleed back and forth between the receiver/servo aside from power from the red wire, and command via the signal wire?Īnother question. Including one where the receiver is still plugged into the power from the ESC and the servo is plugged into the power from the BEC. I've seen a dozen different diagrams on wiring them up. I do plan on throwing in one of my high voltage servos. I'm getting ready to order a Castle BEC and I'd really like to order it in a higher voltage (7.2+V) I'll likely end up getting one for each of my crawlers, but to keep it simple I'm working on a Wraith with a stock ESC and receiver. I'm planning on ordering one and I just have a couple questions on their operation. Yes I saw the stickies, they are doing their job. I'm kidding! Please don't have an aneurism.
