Power for Receiver Ok, I have to ask a dumb question. The Yeti XL will be my first kit. I'm still assembling a parts list and I came across something that stumped me. I plan to run 4S, but want my electronics to support 6S. I will have an external BEC for my servo. I will be using a Mamba Monster 2 for my ESC, and an Airtronics MT-4 for radio. The radio comes with an RX-671 receiver. The receiver has a 7.4V (2S) input voltage limit. So my question: is that what I use the BEC on the Mamba Max for, supply voltage for the receiver? I just set it to 7.4V or less for the receiver, and the motor will still get 4S or 6S? Thanks, Dummy |
Re: Power for Receiver The external BEC will only affect voltage to servo, and auxiliary ports in the receiver. If you plan on running led lights off of your receiver auxiliary ports just make certain the led's ou use are rated for 7.4v or more. adjusting BEC voltage has no affect on the ESC output to the motor. If you use 4s, then you motor will get 4s power to the motor. If you use 6s, then you motor will get 6s power to the motor. |
Re: Power for Receiver Ok. That's what I thought but just to be clear I don't plan to wire the external BEC so it powers the receiver at all, so I was assuming the receiver (and hence the aux port) would be powered by the MM2 internal BEC. ...therefore I just need to configure the internal BEC to say 7V or less Correct? |
Re: Power for Receiver Yes..Thats the nice part of running a ESC with an adjustable internal BEC voltage. You can use a Castle 10amp external BEC to power the power hungry servo at what ever voltage it needs and then use the castle link to adjust the internal BEC to a safer voltage for the receiver and other gadgets you have hooked up. |
