I'm undecided on what to do, and I dont want to use the esc built in bec.
My conservative route would be either a receiver battery or a separate bec module to power my electronics. Western robotics midrange bec is rated for 5 amps, the better one is the $100 unit and i dont want to touch that. On the other hand i can use a 1000mah - 1300mah 2s lipo to power the electronics. Then there's a weight problem.

The bec, when failed, it will pass full voltage from the main to the electronics and fry everything. This in one big reason i'm so paranoid about a bec, or any bec.

The trex 550e is technically like a sub 30 size heli right. So just a small light weight 1300 mah 2s rx lipo shouldn't hurt it much, no?

What are you guys doing to yours 550? Any of you run a separate receiver pack on your 550? Or perhaps a bec, anything reliable?

Three align 610 on the cyclic and one 620 on the tail, do you think it will draw more than 5amps, do you think the hercules 5amp bec can handle it?

The built-in BEC of the Align ESC is sufficient and works fine. The only problem I've had with mine is that the ESC went up in smoke a couple of weekends ago as I was about to lift off for a flight. Fortunately, it didn't catch fire and burn the heli to the ground.

When the ESC went up in smoke, 15 of the 30 MOSFET transistors on it were cooked beyond recognition, only one had the top of its package left intact. In spite of that, the BEC continued to operate and none of the remainder of my electronics was damaged.

This is the first Align ESC I've had that's gone up in smoke. I just finished installing a Castle Creations ICE 100 ESC in its place, it's got a 5 amp, output voltage programmable, built-in BEC. Should be just what the doctor ordered.

There are a lot more things that can (and will) go wrong long before a well-designed and executed regulator will toast your radio. Time to stop being paranoid about regulators, BECs, and ESCs. Batteries have been known to fail, as have the soldered/spot welded connections between cells. Perhaps you shouldn't use any form of battery, either...

The built in bec on the ice isn't good enough. It won't work. You will need a pro bec.

you can't use the bec on the ice 100 for your heli.I think I read the bec on the ice is only good if you're using a small cell count lipo(3s max?)
I have the ice 100 on my 600esp and am using the align 6a bec with an outrage 2200 mah pac with no problems.

The standard ICE 100 BEC:
Phoenix Ice brings the ability to run at input voltages of up to 8S* (33.6) and use the built in switching BEC to output up to 5 amps of servo power all the way up to the 8S max*!
The "*" leads to a footnote saying that the ICE LITE is good only up to 6S.

So, with the ICE 100, you CAN run up to 8S, AND use the switching regulator which is rated up to 5 AMPS.

The stock Align RCE-BL70G ESC has a BEC that is good for 3A continuous, 5 amp burst. The Align ESC is good for only up to 6S input.

The BEC on the ICE is at least as good as, if not better in the current rating department as the stock Align ESC. There should be no need for a separate regulator and/or battery.
I think I read the bec on the ice is only good if you're using a small cell count lipo(3s max?)

I've sent an email off to Castle to see what the continuous rating of the BEC is. Clint Akins has so far responded that he is looking to find out WHAT the continuous rating is. He does suggest a larger BEC than 5 A peak on helis larger than a "500", so maybe I ought to look into buying a separate BEC anyhow.

I used batteries for awhile because I didn't trust the reliability of a BEC. But since have switched to an external BEC and love it. It has been reliable for a couple of years and saves the worry of "Is there enough charge in the recv battery to fly ?" This is on a 10S setup so no internal BEC was available. It was battry or BEC.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

Dave,
I am running 8717's and they have been known to be a bit on the power hungry side,don't know about the OP's ds610's,but I do perfer the safety of the seperate BEC.maybe Clint can shed some light on this,please report back on what all he says.

That is correct ! period

Clint at CC e-mailed me and said CC BEC pro is what is to be used on the 550

clints response

This would be the best way to run the the BEC Pro with the 550 and the AR6200. I don't use the internal BEC on any Heli with Blades larger than 425 mm. Thanks very much.

I am running an ICE 100 on my 550

I suspect I'll get the same response from Clint, too.

Yes, 8717s are known to be power hungry, you don't get performance without sacrifice.

My 550 seemed to be quite happy with the stock Align ESC/BEC, though, and as noted, it's specs aren't quite as good as the ICE. Guess I wouldn't even be having this conversation had my Align ESC not exploded on the ground to begin with. I'd be out flying.

Thank you everyone for the helpfull respond.
I fly nitro helis, and the trex 550 is the 'only' electric heli i have!
Dealing and handling receiver battery in not new to me, and topping off after every flight is no stranger either.

What kind of bec are you guys using on your 550.

I will probably go with a light weight 700mah to 1000mah 4.8v or 6v receiver pack and top it off after every flight. simply for redundancy and safety reasons. I just simply don't trust a bec at this kind of voltage, i thought about it and i feel more confident if the electronics power system are completely isolated from the main.

I knew the ice wouldn't work because I tried a 75 and 100. It's crazy because the align works and ice is suppose to have a bec. I also called clint when I first got my 550 and stated the same statement as above. I put my bec pro and ice 100 on the side frames and I run a 2100mah 2cell align mount under the battery tray.

Wait, so you're saying you run a separate 2s receiver pack and run a regulator at the same time? Doesn't that make your 550 too heavy.

Hey.

Thought I'd chime in with my experience of the CC ICE100's BEC and 550.

I purchased the ICE thinking that not only would it add a little head room over the stock Align ESC, which while this ESC worked well got a little hot for my liking but it was the original grey heatsinked version.
Anyhow the ICE100 has, on paper anyway, a much better BEC at 5amps continuous but I found if you set the BEC output at anything other than 5 volts all the models servos would jitter terribly along the the Spektrum lights flickering. This indicating that the BEC isn't very smooth as the symptoms I was seeing were caused by the switching BEC circuit.

Another ESC proved it wasn't a duff unit so I duly fitted a CC BEC PRO which is working flawlessly alongside the ICE100.

Does the cc pro bec uses a programable voltage that you program with the usb cable? If so, when this unit for some reasson were to fail, would it not regulate anymore? Meaning it would pass full, unregulated power from the 6s pack to all the servos and gyro? Thats 22 volt to the servos and gyro!
I have seen this incident happen to their 10amp bec before. Not trying to bash anybody product, but i'm an ex-castle creation usser here.

Hey.

There have been reported failures yes, but this is a risk with anything and is not limited to CC products.

From memory the most reported ones were where users had not secured the input wires ferrite ring to the model, so during flight said ring was flapping around putting undue strain on the wires.

Not with 4200mah. Haven't tried with my 5000's yet.

A 2S pack and an extra regulator would not make the 550 too heavy. This heli has a ton of power even in its stock form.

I use the Western Robotics BEC (WRL-HBEVHC). It is lighter and more reliable than a battery and switch.http://www.helidirect.com/western-r...rent-p-4666.hdx

The CC BEC Pro is also very popular but you need to have a Castle Link PC interface to set the voltage.

With the 550e it’s important to keep it as light as possible.

That Western Robotics item seems to want to use a 3S LiPo.
