Bec's are typically 5 volt. If you have a digital tail rotor servo they like 6 volts for faster, nore powerful action. So you add a 6 volt Bec.

With a 3S lipo, the BEC on the CC35 is good for a maximum of 4 micro servos- but that's if they're not "high torque" types. (Those are the limits from Castle's instructions).

If you want to run 4S, digital servos or just have some more safety margin, then the add-on BEC is the best deal. The add-on BECs dont have the heat issue that the CC35 has, so are able to deliver more current without shutting down.

If you are running a CC35 with a strong motor such as the 430L, you need a separate BEC or there is high risk of overheating. I fryed a cc35 with that motor. A separate 6V BEC will result in better servo response (make sure they are rated for 6V), and cooler operation of batteries, ESC, and BEC. I like Quark ESC and Medusa BEC.

BEC install question, brain is stuck !
Guys I'm with Dan on this whole confused about BEC's thing. I do understand that the CC35 BEC that I'm running gets hot as heck under normal situations. I'm guessing that is because its working very hard to get the 11.1V (roughly) down to a usable voltage to operate the servos and gyro, correct ? What is the CC35 voltage output into the rx, anyone know?

Knowing this could fry my ESC, I bought a Meduse Research 2.0 amp 6V seperate BEC. The problem I am Not-comprehending (and I know its easier than I'm making it out to be!) IS how to wire the darn thing into my setup. I went to Medusas website, downloaded the manual for the 2.0 amp BEC, read it, and looked at the diagram. Here is a .jpg I made from the .pdf .

In the picture, it says to ...
1. Wire the red and brown input leads along with the input leads to the ESC together. OK got it.
2. Remove or unpin the (Red) wire from the center of the ESC to Rx lead (the ESC's BEC, correct?) and heatshrink it. Got it.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3. Is where my confusion is... now I have 2 (to Rx) leads, one from the Medusa BEC and one from the CC35 to channel 3 on the Rx.

WHERE does the Medusa BEC lead plug into the Rx ??? And please don't tell me I need a 7ch rx

My setup:
Trex CDE
Apex 3s 2100 15C
x3 HS-56's
401/9650
JGF 450th / CC35
Electron 6

I have not done this so don't quote me on it but i think the two lead from your BEC. go into your ch. 5 gyro signal pin, as you know that lead has only one wire in it (signal yellow) or white and all you are trying to do is pawer up the reciever using any open (POSITIVE RED) and (BLACK common) ch.

you can plug the line from the BEC in anywhere you want...

Rx's don't care where the power comes from...

if you do not have a free channel, then use a "Y" cable and plug it (shared) into ch5 with your Gyro gain channel...

I'm old, bitter, and don't like people.... get over it

All you need to do is plug the BEC into any open receiver channel to get power to the receiver. If you have all 6 in use because of the 401 gyro, you will need to piggy back into any channel. Futuba for example used to send a short lead with their better radios which allows you to plug in two leads into a single channel. You can put power in through any channel!

S76,

I use a Futaba dual servo extension like this on mine:

Works great.

Thanks for that info guys. I have a BEC on the way now and would not have figured that out, now to dig around to see if I have a y connector.

Awesome Guys! Thanks for the clarity. Dan, sorry for high-jacking your post there. When are we flying again, you have to see this Trex fly in person, it Rocks !!!

I would personally use an external BEC with ANY CC ESC's.

I just had this same issue. I was overheating a CC35 after about 5-6 minutes. It got so hot it melted away some of the clear wrapper. My T-Rex uses the AON 3000 and 4 Hitec 56 servos and Electron 6. I spoke with the service folks at Castle Creations. He stated that the CC35 and 45 have a BEC that may overheat with the Hitec 56s. They draw more power than others, even the Hitec 55s. He suggested I try the Ultimate BEC (only $30)from Kool Flight Systems. It was here in 2 days flat and on the T-Rex quickly. Solved the problem! I've been flying over 10 minutes now with no heat issues. Bruce.

Same problem with the CC25, started melting away the heat shrink. Why don't the internal BEC's use the same method as the external?

I think that size and cost are the issues here. Maybe I am wrong.
