| Maximum load of a Futaba Rx?
I was wondering what would be the max load I would want to put through a Futaba R304SB 4 channel Rx. I currently run a cc bec to power the Rx to 5.9v. Also plugged in to the Rx is a Hitec 7955 servo, tekin fx-r (with the power wire cut) and RC4wd winch with a Heyok winch controller. I have been running this set up with no problems, but I am going to finally add lights. I will be adding the Gearhead Trail Torch (4.25") and a six more leds for headlights and tail lights controlled through the Tx via Heyok remote switch with dimming. The last thing I want to do is burn out my Rx. Will I be ok with adding lights powered through the Rx? I know the amp draw will be minimal from the lights, but thought I would play it safe and ask here to hopefully get some opinions. Thanks! |

It will take up to 7.4v You are running at 5.9v now...you have room to crank it up.

Thanks Johnnysplits, but the Gearhead light are designed to operate off of 5.0-6.0v, so I don't want to turn up the voltage. I am worried about the amp load that will be going through the Rx, not the voltage.

Ok thanks again Johnny! Appreciate your response. I couldn't find anything on the net about max amps the rx can handle.
