Power your receiver and servos with the baddest of UBEC power solutions. The all new Turnigy 7.5A UBEC is an advanced switching DC-DC regulator which will supply a constant 5A or more with short bursts of up to 7.5amps. The Turnigy UBEC plugs into a 3 - 10 Cell Lipoly pack and supplies a constant 5 or 6v to your receiver. The system includes an anti-short circuit and overheat function with a thin metal shield cover, reducing noise Also included is an Output filter to reduce noise, an on/off switch and a step down regulator adapter. Chip efficiency is 92%.
If you have a mid sized plane, with standard servos and want a solid UBEC which wont quit. This is an excellent option.
Spec. Output (Constant): 5v/5A or 6v/5A Input: 8v-42v (3-10cell lipo) High Voltage Size: 48x27x9mm Weight: 37g Quiescent current: 20mA Type: Switching, however because of the noise reduction (thin metal case & filter) this unit gives the same noise as a Linear BEC.
I am a bit dubious re the quality of the switch used on these BECS. I bought 3 and one switch feels very light on movement and could move one its own due to vibration.
I don't see much point in using the switch for EP models so have cut it off. I think for my glow powered models I will change to a better switch. At least I don't have to worry if the switch goes open but not a happy ending if it decides to move itself due to vibration.
This is not the BEC I would use for IC! These are designed for electric powered models with a 3 cell count. I must agree with you about the switch it is of little use. I would recommend that you look at UBECs or SBECs for 2S for your IC, the thing that you need is Amps more than input Volts. The problem with some high Volt UBECs is that if the input Volts is lower than their design Input they can put out poorly regulated voltages, another manufacturer's UBEC damages a high speed servo by outputing 6.8 volts when connected to 2S yet regulated perfictly at 3&4S.
Don't worry about the switch: I've cut the switch away ( the conntact is open) and the BEC is working *). The switch works in another direction: If it closed, the BEC is off. If you e.g. lost the switch during flying, the BEC works fine.
I was wrong about this Turnigy BEC when i gave it high marks in the discussions. Today after only 4 months of use on my HK600GT this BEC died in mid-flight and caused a crash of my heli. If I were flying higher or more aggressively I could have lost everything I regret buying two more for my EXI500 and my 700 heli and I will not risk using this BEC again
It's at every time the question: FBL or Flybar* Analog or digital Servo's. If you use e.g. digital Servos and FBL your Peak-Power (A) is much higher. If you use analog Servos and a Flybar, the BEC should be enough - also for a 600'er Heli. MY BEC for the FBL and Digital Servo's contains a BEC for 15A (!). The HK 600 with Flybar and analog-Servo's has no Problem with this BEC.
On paper this looks good, but comments aren't so (good).
Which UBEC would you then recommand for a 500 flybarless running 3 MG 930 digital ?
40 thumbs up!
I'm using this BEC on a Logo 500 flybarless and it's not up to the job. After about a minute of flight it will overheat and drop belos the critical voltage on my Spectrum receiver causing a reboot, not good on a flybarless machine as it totally freaks out. I have managed to replicate the results on the bench so if you go flybarless I think this BEC is not up to the job.

Cant really say if this is good or not. mine was delivered with parts broken inside, it does work but would trust lossing a plane with it.
Ordered two of them. one works fine, the other UBEC was without funktion. 3 Stars anyway...

Funciona con servos de regular consumo, sin embargo con servos digitales y receptor 2.4 MUCHO CUIDADO, NO PUEDE CON EL TRABAJO, POR LO CONSIGUIENTE DEJA SIN ENERGIA SUFICIENTE AL RECEPTOR, lo que puede provocar perdida de respuesta del receptor y bye. recomendable para aviones de 4 o 5 servos estandar.
