Wanting to ask a question about ESC wiring.

The plug from the ESC to the REC.

Basically all that is required is the signal wire - IF the receiver was receiving power from another source correct?

The Black and Red are the BEC supply to the receiver?

I am running a single cell 3.7v lipo for a 1/12 pan car - to an original GTB esc - Now the GTB receives its POWER to operate from the battery correct?

It does not receive any power from a RECEIVER battery???

In otherwords if the BEC is not feeding power to the receiver.. would the ESC receive power from the Receiver Battery through the receiver harness red/black?

The GTB says BEC is 6v 3A - meaning this is the max it can deliver assuming the receiver and servo could draw up 3A.

What I want to do is put a Booster circuit between the ESC harness to the receiver - therefore boosting the BEC supplied voltage to 5.1v because I assume if the ESC is only getting 3.7v from the battery it will only supply 3.7v thereabout to the receiver.

Now the Booster says it will only handle 1.5amp max draw - but the way I suggest to wire it there is no draw from the ESC correct? SO the only draw if from the receiver and the servo, and that would be no different than if I wired it direct from the battery posts and plugged into the battery slot on the receiver.

Does this sound like I know what I am talking about????

Thanks

BTW - I've done it - it powers up.. and everything SEEMS to work.. I am wondering if I will do any damage with it being wired up this way.

You are thinking along the right lines. I run a GTB2 in my oval pan car, running a 1s lipo. I've used both a receiver pack and a novak 1s booster.

You are correct that the speedo will be powered by the battery pack. For the rest of your gear, the speedo is sending current out thru it's bec circuit on the red wire to the receiver. Since you are using a 1s pack, the most it can send out is 3.7v. Not enough for receivers, servos, and a transponder.

Both the receiver pack and booster work equally well. I've got one of each in my two separate cars. What I've found works best is to:

1) Switch everything off
2) Turn on the radio
3) Turn on the booster or receiver pack
4) Switch on the speedo for a couple seconds, then switch it back off

You should be good to go.

The alternate procedure is to remove the red wire from the speedos receiver harness. In this case, Step 4 will become "switch the speedo on and leave it on".

Either way, the speedo is no longer powering the receiver now (it's OFF or disconnected). So you can now either plug a receiver pack into the receiver (into an open channel or the BEC jack) and power your electronics that way. OR, you can hook a booster up to the battery leads (at the battery connector or ESC side - both work). Then plug the booster into the receiver (an open channel or the BEC jack). This will take power from the pack, correct the voltage, and supply it to the receiver.
