Disconnecting the BEC

[wppracing]

Going to run an RX battery pack and want need to know which wire to remove. I have seen pictures of the blue or red wire unplugged.

[RayR]

Use a short servo extension and cut the middle (red) wire. Then no need to mess up your speedo plug.

Where are you removing the red wire from ? The ESC ?
A picture will help...

[Fluid]

He showed you a picture. You do not "remove" the red wire. Simply cut the red (middle) wire in the servo extension. Plug the modified servo extension between the ESC and the receiver. Voila.

I use the same method it saves you when you sell your equipment!

Got you now. I was stuck on the wires going to the motor

I never cut my wires. I just pull it back out of the esc itself. Use a small jeweler flat head and lift the small locking tab and slide the red wire out..... no extensions no ruining a esc takes 5 second. I just place a small piece of heatshrink over the exposed wire.

* I do like the extension idea though for quick switch between different setups.

what does the bec do to start with and what advantages does it have by disconnecting it??

[LiPo Power]

BEC is power to your receiver.
By disconnecting the power to receiver and using external power source like stand alone battery you will save the esc from failing....

Battery Eliminating Circuit..

Its in the esc, it takes the main battery voltage and reduces the voltage to provide power the rx and the servo. By removing/dis-abling it it ttakes added work/stress away from the esc increasing the life and durablilty of the esc. Most HV esc'c do not have bec. With added main battery voltage the harder the esc has to work to reduce the voltage for the servo and rx. Now this isn't the best answer or most technical by any means but you get the idea. I am sure Fluid may be able to provide a better idea on how this all works.

On most 2s-6s esc's such has the Hifei and Seaking (non-hv), I don't use the esc's bec on anything over 4s... That is just me, I also don't run those esc's past 5s. Once again just a me thing. I don't like pushing those to the limits. Not worth it to me...

Ooops, you posted while I was typing... lol

Didn't mean to repeat the similar answer.

so if you just remove the center wire what are the other 2 wires for?
and where do you connect the external battery power too ? can you connect to any other port on the receiver?

Signal and ground...

Your rx should have a batt/bind or something similar slot That is where i run my rx pack. For the most part any slot will work though unless you have a telemetry rx.

ok so is a 6volt nimh hump pack battery ok for the power supply?

Yup..Its what I use.. http://www.gshobby.com/index.php?mai...ducts_id=11131
