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)
absolutely horrid!! Shipped in Heli mode, good luck changing without card!! Bad directions, the number of beeps to change mode isn't reached, documentation a joke.
Once it works (via friend's card) it's great.
I'm about to go fly my plane in heli mode, 2 hours trying to program wasted. Very hard to tell from ad that this is shipped in Heli mode. My card will be here someday. Very frustrating, please list these as HELI esc's. Or usable instructions.
this is the best esc that i have used in all my 450 size helis ,3s to 6s .I use the internal bec with out any brown outs on power hungry servos,and the gov store is just incredible ,here is a vid of the x3 using 6s 1300 turnigy packs * 3200rpm for the first half then 3650 second half of the vid ,as you can see the gov does not skip a beat
That motor is a power hungry beast. I have a couple and they would kill a 40A ESC and a 45 as they can easily pull 50Amps. I use 60A ESC's with mine. Certainly would not even consider either ESC's you mention. General rule of thumb for safety is for your ESC to have a 15 to 20% overhead of the maximum your motor can draw.
That motor will be ideal. Run it with a 12 tooth pinion and it should pull approx 30Amps, so the 40A ESC will do you just fine. Also that Typhoon is a cracking good little motor. Give the bearings a drop of oil every half dozen flights or so and they last for ages!
These really are excellent ESC's, and really do perform well. But, if you are wanting something different, go to a 6S setup. Use a 1700kv motor with 12T pinion and a 1300mAh 6S battery with this ESC and you get one seriously powerful heli. Everything runs much cooler, you get longer flight times and far more power to really wring your heli out. I went 6S with all my 450's last year and have not looked back.
Also check the RX antena.unsrew the reciever and check the solder,if thats ok make sure the antena isn't touching any metal or has any breakages.Also make sure you use fully charged batteries in your TX if you use rechargable ones and if there quite old get new ones.If not buy new batteries.
I think this ESC have a Software Problem.
When I connected the ESC does 3x peep! = Lipo 3S, but after 10sec. the ESC goes to undervolting and the Heli must landing! I have a Programmcard and reset the ESC to other Akku type.
After this I can only 3 Flyts and the ECS make the same.
Hmmm. Unusual. I take it your batteries are healthy? I honestly have never had problem with these YEP things, and I use them exclusively now in my helis and EDF jets. Sounds odd, but I wish I had a problem one to try and figure out what is going on.
After the second flight the ESC goes with Cardprogramming programming(2,2/2,9) after 2min flyingtime to undervolting. Reconneted and go on flying with the same Lipo over 3min. Now I have programming to cutt of type->OFF.
Now I can fly, but without Cuttof, and the ESC play only Melody when I conneted.
Motor -> Turnigy 450 H2218 (3550KV)
Lipo-> Turnigy 2200mAh 3S 25C (but also with 2800mAh S3 35C Lipos)
ESC->Brake of, cuttof->off, cuttofV (2,2/2,9), Special F->AutoTiming,GOV with Freew,GovModeP->1.2,GovModeI->0.03,Startup->Heli slow, PWM->8kHz, StartPower->Auto
And I fly always only 5:10 min. = Lipocharger load 1420mAh to full Lipo.
Whats are better, undervolting and emergency landing, ore no Lipo proteting and can flying?
I think Nr2 are better :-)
I set my LVC at 3.2v and land before it ever cuts in by using a timer on the TX that beeps 30 seconds before it ever touches LV. I set LV cutoff to 'slow down' as 'cut off' would make you autorotate to land.
Admittedly I only have 6S setups, but even so I really am surprised it is hitting LV with those batteries though.
Righty. Set one up with same motor as yours. 12 tooth pinion. NanoTech 2200 25-50C pack. ESC timing - 18deg. Brake - off. Cut off - slow down. Accutype - LiPo. Cut off volt - 3.2. Cells - auto. Specials - stop and full speed set via throttle as normal. Act freewheel - off. Gov - off. Pgain and Igain - N/A. Startup speed - heli slow. PWM freq - forgot but pretty sure it was 8kHz. (But I know I have run 12kHz before) Flew well hovering about and mild sports for just under 5 mins. I landed and did hover until LV kicked in. Second battery just the same. No problems at all. ESC behaved normally.
First of all the sound from the motor gets louder and quiter when the outer shell is moved a little bit,i think it resonates of the magnets thats not a problem.First you must rest the ESC by turning on your TX and put the throttle to full then plug in your heli.Wait for all the beeps to stop.keep the throttle at full then Unplug your heli and the ESC will be reset to default .Some errors are recorded in the ESC and some arn't this will delete all errors.Then plug in your program card turn on your TX with the throttle all the way up and turn on your heli.This will start program mode.Then do what you need to do program wise.Make sure you set throttle STOP and throttle Full on your program card and all should be good my friend
So they seem to be the same as YGE, but they are notified 6A bec and YGE has only 3A Can anyone confirm that?

Recieved the helidrive 45a the other day and have managed to get it into my 450 pro, I have to say that the lack of instructions was dissapointing however it is the same as the YGE esc that everyone is referring to in the discussion area and the manual uploaded in the files section is the correct one.
First impressions are that the build quality is excellent and silicone wiring is used for both motor and battery connections.
I purchased the programming card with mine also which made programming the esc much easier, i'd recommend buying it if your considering one of these esc's.
Flight characteristics are excellent, throttle response is very fast and precise with the governor mode being exceptional. The overall feeling of power gained from using this esc is impressive.
I have only done a few flights with it installed so far but there are no signs of any issues so far.. I will keep you all posted...

overall very nice esc well put together,thought out and looks cool too, most important bit it works great, little heat build up very smooth throttle response and start up silky smooth,im running with a 2215h typhoon and 30c turnigy and it goes hard!

I use this in a hotliner sailplane.Low height of ESC allows it to slip into narorw fuselage.Excellent programming using card.Will by more,very good value for money.

reveiw update: this esc is just awesome, gained an extra couple of minutes flight time over my old trust, runs almost cold even with a few full pitch dumps and startup is sweet, no more smooth start then a bump in power up to go,also the gov mode seems flawless ,to me anyhow! verdict, i bought two of these and id by more in a flash.Cheap doesn,t mean nasty anymore, very happy!
