Volt up! Gear down!
New and improved with thicker 22ga wire and lower resistance for more power!

This adapter allows the use of an external BEC for servo power without needing to disable your ESCs internal BEC. Servo and BEC plug into the double plug end, and the single side plugs into the servo RX channel. Servo gets signal from the RX, and shares a dual ground path to both RX and external BEC to prevent floating ground issues.

Must have for any crawler running over 300 ounce/ inch servos!

Get yours today here Holmes Hobbies LLC

I need one,have just got my order came through today #14282...
The dual br mini esc...
I will buy one when I buy my motors in juni...
Thanks man,,,,
Great service
 
Wow. I'm new to all of this (researching everything prior to building my son a SCX10 G6) and I've been trying to sort out all of the BEC mumbo-jumbo and after reading what feels like hundreds of threads and links I finally stumbled upon this little thing.

SUH-WEEET

Both the wiring method that comes with the CC BEC and the servo power only method look like hack-job rats' nests to me. Cut this, unplug that, splice those....

No thanks.

But thanks Holmes Hobbies. I'll be adding this to my motor order.
 
I'm assuming this plug will work for running 6ch. Into a 5ch rx then?

I use the 4pl and I'm planning on running 3 big servos(2 for steering and 1servo winch) 2 Esc (1 for winch control )and a Bec on a current build im working on and was really hoping I wasn't going to have to go to a stick radio....

I'm no wiring guru but if you would recommend this for my setup I will be ordering a few of these!

Thanx
 
It would open up on slot on the RX if you are currently plugging the BEC in directly, but it would only power the single servo that it was plugged in to. If you are needing full control of all your servos and ESCs then a 5 channel will be your only option.
 
Thanx that makes sense now. .. wiring hurts my brain :oops: your old wiring diagram years back in a crawler magazine helped me wire ALOT of MOA's but these 6 and 7 channel scalers can get a little more complicated.
Thanx again!
 
I recently bought one of your bypass adapters, and I LOVE IT!! It kept me from having to buy a new radio to get one more channel. With lights, a winch and a BEC, channel space on my receiver was non existent. Now I run my lights in my bind port, my winch on channel 3, and my BEC and Servo are in the same channel. So simple. So efficient. So smart. Thanks HH.
 
I tried to find a wiring diagram for this but couldn't.
Using a Castle BEC, does the BEC plug brown wire plug into the adapter black with the servo plugging into the 3 wire side?
And than cover the black and red leads on the other side of the BEC?
Here's a pic cuz I'm probably not clear.

I was going to ask a question about splitting these, or putting two of them together, but realized I'd need a Y-adapter to do it. So how about a product idea instead.
2 male ends going to two different channels on the receiver with ground and signal, two female ends with power, ground and signal (from each of the male ends) going out to the end devices and the single female end from the BEC splitting to provide power to the two female ends?
Does that make sense? Basically, I want to power my servo and winch using these.
 
Not a must have, but it saves a lot of wiring hassle and ensures the servo power is isolated from the radio power. This effectively eliminates brownouts from servo load changes.

Cool...Answer the phone so I can get one and a BEC on order...paypal does not accept my stupid gift card and my LHS is out of waterprrof BECs...
 
Another option would be to spend the money on a little better ESC with a better internal BEC. The Tekin FSX will give you 5.5 Amos continuous. The RX8 Gen 2 gives 7 amps continuous, though is a big ESC.

Castle ESC are good and they are priced well. Their BEC's however are notoriously weak. Castle practically owns the ESC business in the RC Heli segment, but even there they are well known for their weak internal BEC's, a brown out on a Heli can be very expensive.

If you want the price/value of a Castle ESC and don't mind running a external BEC this by-pass is a great deal I think.
 
What do I set the ESC BEC down to for radio power?

The External BEC will be set for servo power...not sure what the radio needs though...
