| two servos at different voltage? how do i do this
Ok I've got an ax10 with a fxr esc, tekin 45t motor, hs-7950th steering servo, hs-645mg dig servo and the flysky gt3b rx/tx. I want to run the 7950th @ 7 volts. The flysky rx is rated @ 6 volts along with the 645mg servos. Right now my cc bec is set at 6 volts. Can i turn the bec up to 7 volts without hurting anything? If it will burn up the rx and 645mg is there another way to do this? I know the 7950th is made to run off two cell lipo but im using 3 cell

Option one: Puke up the dinero for a 2nd BEC run one BEC at 7 volts wired direct to your 7950, the second BEC you'd set at six volts connected direct to your 645. The Rx would be powered by the FXR's internal BEC. Option two: Run your current BEC at 7 volts connected directly to your 7950, run your receiver off your FXR's internal BEC, and your 645 plugs into the RX. Option three: Run your current BEC at 7 volts connected to both servos, then you get to guess at what resistors you'd need between your 645 and your BEC. Option four: Run your current BEC at 7 volts conected to both servos and let fate have it's way with you. Might work, for a while. |

If i went with option two i would just connect the red and black wires off the bec directly to the red and black wires on the 7950. Then the signal wire from the 7950 to the rx and disconnect the signal wire from the bec? the fxr should be ok just running the 645 and rx on 3s? Thanks for your input trubble.
