How Do I Remove_______ B.E.C. ?

[boatman1938]

I have a Futaba R142JE 2-Channel 75MHz AM Mini Receiver with BEC. and I'am using a Hitec HS-805BB+ Mega Quarter Scale servo it says do not utilize the B.E.C. ___________________________ My question is how do I remove the bec from the receiver?----------------------------------------------
I will be running 4.8 volts -with 4 2600 Mah Batteries. Gas boat 30cc homelite motor 48?long 15"wide 14 LBS
Thanks Dan

Ok easy one this you dont need to worry about it as you are not using a Esc with a Becc supply

Dan,
There was another thread simular to this, delt with by-passing the receiver's BEC. The answer seems to be to use a 'Y' cable between servo/battery/receiver. One arm of the 'Y' goes to the battery, one to the servo, and the other one to a servo jack on the receiver ~not~ the battery jack.
If a Bec is built into a receiver (actually a voltage limiter/regulator), especially a 'mini' receiver, there's very little chance of removing it unless you know enough about electronics to understand how the circuit is put together and can identify the parts. The smart thing would be to not attempt removing it, but just by-passing it (the reason for the 'Y' cable thingy).
Another thought is that I wonder why the manufacturor didn't design the receiver and BEC (limiter/regulator) to only affect the receiver's input voltage instead of everything powered through the receiver? And then again, I may be misunderstanding the whole mess...

Like this for a gas boat with a 30cc Homelite?

Hi Boatman,

As you're using a 4,8V powersupply for the servo(s) and the receiver, you can plug the powersupply in the "batt" input of the receiver, no problem.

To power the receiver and get a signal to the servo, the Y-cable comes into play.

Basically the steering servo get's its power from the battery and the signal from the receiver, hence the Y-cable.

Running 4.8 volts 2600 Mah.____________ First photo or second photo which is correct?___________________ I can leave ch2 blank and still be able to run the rudder servo?

Dan,
Guess I should pay more attention to what's asked before jumping to conclusions. If you are going to use the voltage recommended for the receiver, 4.8 volts, then the 'Y' cable shouldn't be necessary at all. Just connect the battery to the 'Power' slot, and rudder servo to the channel slot you are going to use for the rudder.
The use of a 'Y' cable is to be able to use a higher voltage battery to power servos which require a higher voltage than what the receiver will 'like' to see, or is capable of handling.
