I just acquired a 550E v2. I've upgraded the 3gx to vbar (full size) add some frame mods to stiffen it. I am looking to upgrade the stock ESC.

I have three options...
(1) the new Castle Talon 90 with large built in BEC ($90.00),
(2) Castle 100A ESC ($119) and a separate Castle 20A BEC ($39.00) or
(3) Hobbywing 100A ESC ($65.00) with a separate Castle 20A BEC. ($39.00)

Those who have a 550E, what would you choose and why? I listed price as a reference, not the reason for my decision.

MY 550e has been working quite well simply using a Castle ICE 100 and using its built-in BEC. I recently replaced the 3G with a 3GX controller, as I was beginning to get some occasional weird tail rotor hits with the 3 year old 3G.

I replaced the stock ESC after it smoked on flight number 12.

Dave, FYI - manual says above 3S to use external BEC, not internal - be careful.

I am using an Ice 100 in my 550. I chose this ESC since I am running 556mm blades and 96mm tail blades (with a 600 boom/tt). I regularly pull over 100 amps and usually max around 130-140 amps so I wanted a little headroom. Temps usually stay below 150 degrees even on hot days unless I really hammer it. I also like the logging feature in the Ice controllers to keep an eye on things. For running 6s on a 550 size heli, this ESC works great.

I run a seperate lipo for my servos since I am running a high voltage setup. I don't trust the built in bec for my 8717s. These servos have been pretty rough on most regulators I have tried so I just run straight lipo power to them without a regulator.

Scott1115 --
Dave, FYI - manual says above 3S to use external BEC, not internal - be careful.
Your observation is appreciated, but absolutely INCORRECT.

Note that the ORIGINAL Phoenix ESCs -- such as the Phoenix 25, Phoenix 35, and Phoenix 45 used a couple of small linear regulators connected in parallel to yield what was advertised to be a 3 Amp BEC capacity. THOSE older Phoenix ESCs were indeed limited to a 3S input.

BUT -- I am NOT using a Phoenix 25, 35, or 45 on my 550. Instead, I am using the Phoenix ICE 100...

From the current Phoenix series user manual we have:
PHOENIX SERIES (does not include Ice or HV models)
You must disable the onboard BEC when using greater than a
3s LiPo on Phoenix ESCs.*

PHOENIX ICE AND PHOENIX ICE LITE
Phoenix Ice and Ice Lite onboard BECs can be run to the
maxiumum rated voltage of the ESC. The maximum voltage
for the Phoenix Ice is 34V (8s)
and the Phoenix Ice Lite is25V (6s).

Helicopters with blades larger than 425mm will need to use an external BEC*. For more details visit http://www.
castlecreations.com/helisetups.
The Phoenix ICE series BECs can be safely operated with up to an 8S input, not the 3S as noted in the instructions for the older Phoenix models.

Yes, I see the admonition about not using the internal BEC if your heli spins blades longer than 425 mm.

Keep in mind that the stock ESC that ships with the 550 has a BEC with the same ratings as that of the ICE 100. Before I installed the ICE, I ran some tests, including stalling all four servos on the 550 while measuring the battery current. I did not reach the rated current output of the BEC, and in flight, you may see occasional peak up there, but the current demand will NOT be at the peak rating 100% of the time.

Scott,
Go with the HobbyWing 100A and get the HobbyWing phase sensor so you can run the Vbar gov..Its cheaper than the Castle ESC,holds headspeed alot better than the Castle ESC and doesn't overspeed like the Castle ESC...

I tried using the 80A castle(forget which one) and the internal bec would not even arm a mini vbar. A friend of mine had the same issue with the same esc and vbar. Upon doing a search, I found others with the same issue.

I am actually in the market myself for a new esc for my 550. I am purchasing a hobby wing 100 and a gryphon bec. I have no experience with the hobby wing but have read some good reviews. The gryphon bec I use on another heli and it has been working great and doesn't even get warm.

DON'T TRUST CASTLE
I'd go with the hobbywing ESC. After my experiences with Castle, I'll never run their crap again. They don't take responsibility for their faulty products the way they should, they have crappy turn around times, and, to be honest, they are a ****ty company in my views.

My Castle HV 80 v2 has been great. Zero complaints, but I went with the Hobbywing 100a ESC this tome around, with the Castle BEC pro.

Interesting. I was using align servos (which I know are power hungry)and could not get the vbar to even arm properly. Servos must of been my problem..
