We are now proud to offer our Hobbyking YEP ESC series. With helicopter specific programming options such as super smooth soft start, fixed RPM mode (governor mode) and ultra high resolution, you won't find a better helicopter ESC on the market today!
We have tested these units on our own helicopters and found them to be among the best we have ever seen. The super smooth soft start, along with its ultra high resolution throttle response puts this ESC in a class of its own!
Hobbyking YEP ESCs are built with the highest quality components to ensure true-to-rating current handling and high efficiency operation.
All Hobbyking YEP ESCs can be programmed via optional programing card or by transmitter stick inputs.
Features: • Powerful 5.5V/6A Switching BEC • Optional programming card for convenient setup • Super fine throttle resolution provides first-rate and highly accurate linearity • Super smooth adjustable start-up mode • Constant RPM mode (governor mode) • Adjustable F3A brake. • 3 steps adjustable normal EMF brake • High anti-interference capability • Low voltage cut-off protection with automatic adjustment for NiCd/NiMH/Li-Ion/LiPo/LiFePO4 • Soft cut-off option at low voltage, slows motor RPM gradual rather than hard cutoff (LVC) • Low voltage cut-off can be disabled • Variable cut-off voltage / cell • Active free-wheeling circuit allows for unlimited "partial load" capability • LED status display • Adjustable motor timing from 0° to 30° • Blocked rotation protection (senses a jammed motor and stops motor rotation) • Motor reversing from ESC (no need to change ESC/motor wires) • Over-temperature protection and overload alarm • Anti sparking circuit: reduces connection sparks (for HV ESC) • Throttle signal lose protection. If the signal is lost for 3 seconds, the power will automatically cut-off. • Safe power-on. (Motor will not start until throttle is returned to lowest position)
***This ESC is compatible with both helicopter and airplane models.***
Specification: Max Cont Current: 45A Max Burst Current: 55A for 10 seconds Input Voltage: 2-6 cells li-XX or 6-16 Ni-MH/Ni-Cd battery BEC: 5.5V/6A Switching BEC PWM: 8~16 KHz Max RPM: 240,000rpm for 2 Poles Brushless Motor PCB Size: 50x30mm Weight: 63g (including wires)
Hi. teach me please.
I get this type 40A ESC. on 450 size helicoptar.
it's good . i use setting card,normal helicoptar setting 3S Batt.
But hi say beep Throttl 0%, beep beep.
what is two beep sund,0% thurottol.
Guys... VERY VERY strange error: Using this in a 450 heli with a typhoon motor, it suddenly stopped working after I accidently changed the motor (not the battery cables though) Now, it won't rotate the motor except when I turn the motor a little - which I did at 100% throttle once, ouch!!!.
So I bought a new motor, but same problem here. At all throttle settings, the motor makes some beeps and gets warm - I've already tried different program settings.
Sorry for the double post reply, just want to add some details:
It's "changed the motor CABLES" but you surely understood me before already :)
What I did was: I plugged one of the outer Cables to the middle cable of the ESC. But as far as I know, that still shouldn't kill an ESC. Now I've tried all the different timings, but the problems were the same. Also, I hurt myself with suddenly rotating rotor Blades (because I didn't realize what was going first. Many later tests just confirmed the problem.
And if you think it could get any worse (you know, correlation-wise): THIS DAMN THINK DIDN'T SMOKE. BESC still working, no condensator seems to be damaged. WTF.
Ok, here comes some "bonus" lament: This was the final strike for me, I AM SO ****IN DONE. I've already had several other problems with my HK450GT (one of them being a terrible gyro), which I eventually solved. But fate/hobbyking once again decided to punch me in the face and invisibly destroyed my ESC. Since then, I have given up.
PS: Anyone else having this problem?
Hey people, I have this on my trex pro v2 and im having little trouble with it so anyone can explain what is going on. When I power up everything is fine and then when I spool up and go to lift off power drops down and I close throttle and hear some beeps, then I power off and back on and everything fine. Im not sure how many beeps exactly, so any ideas??
Has anyone else had problems with the current version of the YEP 45A (the one with separate programming and reciever leads) operating with ORX receivers? Mine will not run the motor with the ORX, but works fine with an FrSky receiver. It looks like boot latency in the ORX is the problem. The Fr Sky rx boots in 0.1 sec or less, while the ORX boots in 1-2 sec. A 1 sec rx boot time apparently puts the YEP into lost signal mode and inhibits the motor drive function.
That's not the problem here. When used with an FR SKY receiver, the unit starts up great. It is just when it is used with a DSM2 rx (either ORX or Sp**trum) that it fails. If used with a servo stimulator, it starts up just fine UNLESS the power to the stimulator is applied about 1 second after power to the ESC. There is a receiver failsafe mode in the ESC, and it looks like the boot delay in the dsm2 protocol activates it.
Super Regler - funktioniert in allen Punkten wie er sollte. Enorm gutes Preis - Leisungsverhältnis. Die fehlende Anti - Blitzschaltung fällt bei diesen Stromstärken noch nicht auf. Das wird mein neuer Standardregler - man braucht einfach nichts anderes nehr.
Very good Controler! First I have tested it without gov. But I had to recognize that it doesn't work with softstart in this mode. The speed change takes several seconds. Flying was neary impssible with that. I think the softstart doesn't have a switch which turns it off after a certain time. It runs permanently. But the gov. mode does exactly what I have expected. Real good apadtion of the speed. The power consumption is great. I can fly longer than with my old ESC. The temp. of the esc is about 36Â°C after 6 minutes of flying at 85pcnt opening. That is a real good value for the money!!! I will by a second of it when I build a new heli.
Very good built. The wires to the motor and battery are very long and soft, easy to twist around corners. I also bought the programming card, there is lots of functions and programming is as easy as pushing a button on the program card!
