Turnigy® TRUST SBEC ESCs have a very flexible and broadly capable MCU, able to run all types of brushless motors.The large heatsink and simple PCB layout make heat dissapation consistant, enabling the ESC to be run at its limit, without failure. The ESC is program-card and transmitter programmable with clear and easy to understand instructions included.
Default factory settings: Brake: off Battery: LiPo Auto Detect Low Voltage: 3.2v (power down motor)
Spec. Max Motor Current: 45A Max BEC Current: 3A BEC Voltage: 5.5v LiPo: 2~6S NiMH:5~12cells Weight: 31grams
Mine goes ka-chunk ka-chunk from throttle off to about 3/8 throttle. Speed transition from off to on is not smooth. Has anyone else experienced this or found a fix?
Nothing really. The amp rate is just how much it can handle in power draw. Only really need to note is bigger ESC will weigh more so could throw some CG off depending were it is.
Brian is right about using velcro and if you mount this inside of the fuselage ensure it has plenty of airflow to keep it cool. Running an ESC on half throttle will heat up more then running it wide open.
Will this esc work well in a quad copter with NTM prop drive 35-36A 910kv motors? I was going to go with the Turnigy plush 40A but I want to order from the USA warehouse if possible and these are available in the US.
This esc will work. You always want to have a bigger ESC than needed with at least 10amps to spare but 5 is enough as well as long as you don't ride the throttle too long.
Well, if I had one..I would give it a try.
I was trying to confirm whether or not the ESC had the capability before purchasing since the specifications for the ESC does not mention having the auto-throttle-shutdown feature.
Sorry Justin this does not answer my question. I am not concerned about the amps for the speed controller. I am looking for information on the BEC output. I see its listed here as 5.5 volts and 3 amps. I sometimes notice these figures are inflated a bit.
i'm pushing 30 to 35 amps through mine. I have it on the yak 55 foam profile with a park 480 and it does great. Doesn't get hot or anything. Hope this helps..points please
What is the dimensions of this ESC? HK didn't write it down. It is important for some applications. Is it compatible with 450 Pro kits? ESC placed under the LiPo tray on the 450 Pro most of the time. So it should be like standart Align RCE-BL35X dimensions: 45mm x 23mm x 12mm.
Anyone know if the BEC operates in Switching or Linear mode? What does the programmable switching option (8, 16 kHz). Does that mean this is switching mode BEC and two frequencies are selectable?
I would assume its a switching bec not liner, based on the sbec the s would stand for switching. The kHz is the frequency of the pulse to the motor some motors need a high frequency then others.
The 8kHz / 16kHz refers to the motor control PWM frequency. The tradeoff is more switching losses at 16kHz (= more heat) since the FETs switch twice as often, but the throttle control will be smoother. In general, you would use 16kHz for larger outrunners, and 8kHz for inrunners, smaller outrunners, and max efficiency
Yes, 'SBEC' means Switching (not Linear) BEC. Nice enough ESC but drawback here isn't heat but the only 3-Amp MAX rating for the BEC. If you have 6 servos on (eg a glider with flaps* warbird with retracts etc) they can pull from half- to just under a full amp in 'busy' ops. Do the math....not good! Best used on light, maybe park-flyers with 4 servos max, or face possible Rx brownout situations - also not good. Annnd....what kind of lightweight parkflyer needs 45-Amp ESC? Wayyyy overkill, ergo penalty you pay is size & weight.
My parkflyer foam Rare Bear funfighter draws 46 amps, clocks just upper 170 mph level flight on a 22mm class motor (not the stock motor). A 45 amp esc is in now way overkill. Be careful making statements based on limited experiences and or knowledge to other modelers.
I'm new to electrics and must confess that I'm confused about BEC capacity. To keep the question simple* would an ESC with a 3A BEC be sufficient for a glider with 6X9g servos? I could go to an external BEC or even a Rx battery but would rather not.
Hi .I think 9 g servos pull only 1/2 amp under heavy load at most. I have a meter that I plug into rx and it shows what the servos draw but never checked 9g servos draw.Onlt standard size and they draw 2 amps, So you should be OK but you might want to borrow or buy a servo meter and double check. GOOD LUCK.
Thanks! That's about what I figured but there's a lot of new information to digest. I'll get a meter by next month but I'll probably just order a 4A-5A UBEC too just for peace of mind. I should be able to hog out enough foam for a UBEC but a hole big enough for a battery would probably need some ply and/or glass reinforcement and I've already added enough weight.
That, I think, would be your best bet. They're really cheap as dirt, & good insurance for the "peace of mind". As they say, better to have and not need, than need and ...
I love this thing! Quality appears very high, flies my .32 size outrunner very well with precise throttle response. Have not measured my current draw yet, but this thing has never even gotten warm on 3s with a fairly large (12/8 prop) on a HK Donkey .32 equivalent motor (900kv or so).
I will order more for an FPV setup I am working on. I do trust this one as the build quality looks great!

I am using 3 of these with various motors and they are all great!
Turnigy Aerodrive SK3 - 3530-1340kv With a 10x6 folding prop The motor and ESC are cool and smooth! (3s lipo)
Turnigy D2826-6 2200kv with a 6x4 the motor and ESC are warm after 20min flight at 80pcnt throttle. 3s Lipo
ARC 2842 1500kv Inrunner with a APC 8x6 bench test only so far, 10 sec full throttle, motor is warm and esc is barely warming up. 20 sec full throttle, motor is warm and esc is warm. 30 sec full throttle, No real change in temperatures.
Overall this is a great ESC!
Rock solid, no problems, no brainer controller. CANNOT beat the price so I bought a few and am VERY happy :)

My Airfeild 55" Cessna 182 Skytrainer's original 30 amp ESC melted on take off and luckily I got the fire extinguished in time. Ordered 2 Hobby Wing Pentium 40 amps to replace the original and have a spare. Neither one would run the motor without surging. Tried them both on my sons Durafly Cessna 182, the same thing. Ordered and received this ESC from HK within 2 business days. Plugged it in and "perfection"! The power is substantially better than before. I can run it pretty heavy-handed without it heating. Excellent throttle control, I love it. And for the price I am ordering 2 more. Recommend this one without reservation. The only thing is it is sizeable and weighty, but if you need 45 amps in an ESC you probably have the room and capacity for it. Great job HK!
