Stupid Question...

[zbert]

Okay, so here's a stupid question but I cannot seem to find any information for this online. If I want to run servos off of my reciever how do I do that? In all the previous models I've had before, I've run a speed control between the batter and reciever. How do I get power to the reciever and servo without that speed control? I know this problem is fairly easy, but it's easy enough that no one puts this information up on the internet. Any help you could provide would be great.

Thank you,

Zachary, You didn't mention the battery voltage. If it's between
4.8V and 6V all you have to do is plug the battery into the power switch
then plug the power switch into the RX. The servos just plug in the RX
and get power from the common + and - buss in the RX.

If you are using a battery with more than 6V, then you will need a switching
regulator with 6V output to put between the battery and the power switch
to keep the supply within the limits. The speed control was providing the
regulated 6V in the previous system.

Ken,

Thanks, I just could find no information on that what so ever. I figured it was about that simple, but I had no info on voltage. When I tried using my 8.4V in that way I got sparks and thought I'd ask first instead of ruining my rx! (Anymore than I probably did). I have a nice variety of batteries, and can always rig up something pretty easily now that I know I'm looking for 6V. Where can I find a voltage regulator for batteries above 6V? Is this a pretty standard number?

Thanks,

The standard Rx and servo voltage is 4.8/5V. Most but not all of them will also be o.k. on 6V. It's in pretty much every receiver or servo spec I've ever read.

The "regulator" you want is more usually called a BEC. Most Speed controls have them in but you can also get separate ones e.g.
UBec http://www.koolflightsystems.com/ultimatebec.htm
ParkBEC http://www.dimensionengineering.com/ParkBEC.htm

I'm sure there are others too.

I used a Koolflight U-BEC in my old Voyager E - nice bit of kit and well worth the money.

As Steve said, the normal voltage for an RX pack is 4.8v (4 x 1.2v Nicad AA batteries) - I found that I can use 5v when I'm prototyping projects in the workshop, but I wouldn't want to stick 6v or more into any RX, even the cheap GWS models !
