Will the CC 10 amp bec be enough for a 450 size helicopter?

I may get beat-up for this but it was my understanding that there have been problems with these in the past. Best to go with something else.

I have a Hercules super bec,I thought it might be to much for a 450. I just may have to use it,thanks.

Wide input voltage range from 9V to 60V (3-14 LiPo Cells). Min. 12V input for 7.4/8.2V applications.
High current capability of 15 Amps continuous 20 Amps peak with proper ventilation
High power output that handles multiple servos with built in power bus system that allows for direct servo connections
Built in battery reverse polarity, current overload protection
Built in digital power on/off enable port (External switch sold seperately)
Specifications:
Height ------ 24 mm
Width ------ 35 mm
Length ----- 56 mm
Weight ----- 36 grams
I know that WR makes a smaller-unit (Mini Herc) but you really can't go wrong with one-of these

I have never had a problem with the CC 10a in a 450 heli or the airplanes I have installed them in.

Most built in BECs in typical ESc will sufice on a 450, even with a FBL setup. An external BEC adds quite a bit of weight and a 10 amp continuous BEC is overkill for this application. You can expect less than 2 amp continuous draw and peaks less than 5 amps. If you have realy power hungry servos then adding a capacitor will reduce the peak current spikes. Here is a [url=http://vstabi.info/en/node/1330]link to the VBar site where they have tested this with good result. I run a 5 amp BEC with caps on my 600 FBL with no issue. Both the VBar and my telemetry tells me that the voltage drop is acceptable.

My experience with most built in BECs is they cause the ESC to run hotter, plus failure of the ESC means total lost of control voltage.

I found that to be true with the linear BEC's that are common in ESCs that can handle 3S to 4S batt3ris but much less so with the ESCs with the switching BEC that are much more efficient and thus produce less heat.

My experience is that even though the ESC fails it does not typically take out the BEC. I have had two ESC burn up and none of them killed the built-in BEC. One of them was an Align ESC for a 450 that I put in to a boat with to large propeller. It burned up both the motor and ESC to the point of desoldering the cables leading to the motor and also burning off the heat shrink on the ESC. It waw quite spectacular but the BEC was still working.

For a little extra money ide much rather run the Gryphon Polaris Mini BEC simply for the heavier guage wire it comes with verses the tiny thin wire on the CC 10 amp BEC. The servo plug on both units should be split off into 2 plugs if anything greater than 5 amps is expected. The new micro servos with over size motors (MKS DS95 etc.) draw quite a bit of current especially along with a powerful Mini tail servo.

You will be fine with it. I am running one on my 450 and it has held up fine and always works. I have one on a goblin 500 and it is working fine. Both are little blue cc 10 amp bec

That is a bit risky! You know at 6s input its only good upto 5A? You need to test what the RX voltage is dropping to during while wiggling collective quickly for 10 seconds on the bench.

Richardmid1, Thanks I looked up the Gryphon on and Im going with that one, better safe than sorry. Thanks again.

I am regulating a 2 a pack because I don't hv servos on it. Believe me the kid shows no mercy on our helis and it has worked just fine. On a 450 like he is wanting to use it on he will be ok

Yes
Will the CC 10 amp bec be enough for a 450 size helicopter?
I use that on my 6s 450dfc works great with all MKS servos. I originally used the YGE 60 internal bec but it failed the stick bang test on the bench with MkS ds92 servos. Bec is set to 6v. There are more attractive options available but cc10 was low cost.

I know some disagree with the stick bang test but it is somewhat of a good indicator if a bec is up to par. I used an old Kontronik jazz (bec1.5a) when I first went fbl. While tuning, I got a nasty bobble in the air and it caused my satellites to reset. Luckily, my Heli just plopped down into high grass. When I learned of the stick bang test, I tried it on the Jazz. Just pumping the collective in TH hold on the bench 5 times quickly caused the SATs to reset.

I now err on the side of caution and use robust capacity on any bec. Any bec should handle worst case in the heli it is installed in.

Well if it passes the stick banging bench test on 6s with all MKS servos then I guess its fine. I too had problems with the YGE (actually YEP) BEC on a 450!
