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 • ESC had separate programming lead built-in so there is no need to unplug from RX • 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: 100A Max Burst Current: 120A 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: 81g (including wires)
Same problems here whit VStabi, DSMX Sats and Turnigy Tgy1258. I dont think the load is the problem (only One Servo and BEC of ESC is studdy) its a re-current Problem. The servo induciate a voltage back to bec. I use 14 Fahrad of condenser (elko), problems fixed.
Had it set up on the vortex vx1 FBL gyro on a 550 3x aling 610 and 1 x 615. if I move both sticks very very fast ALL servos stall for a second and then carry on and then stall again. never did this on any other FBL unit .
Hi: Thanks for the quick answer!!! Ok, I understand... the temperature problem is solvable with a good cooling, I guess. the question is* can you program this esc for a gupistol radio? How can I do it?, with the programming card?, with the transmitter? Sorry for all the inconvenience
100 AMP YEP ESC Does anyone have the directions for programming this thing with the programming card?? They have no information, apparently someone hacked in the files. They are telling me it can be up to 6 weeks before they get them back online. Now I have this ESC with a programing card, unfortunatley withpout some direction I cant't use it
This ESC does Not work properly with a Turnigy Rotomax 1.20 engine, it will work & you can set all the different program's but if throttle is advanced fast the rotomax engine squeals & locks up until a lower throttle setting is chosen. I have this setup in a Yak55M 30cc with Zippy 6s 5000mAh 40C LiPo spinning a wood 20x10 prop. however the engine does the same thing with no prop, I have tried all settings for timing vs Htz & combinations of all different settings.. Suggest not to purchase it to use with Rotomax 1.20 engine .. otherwise a good ESC quality & build & construction excellent....
Not sure what Esc to purchase now to use with my Rotomax 1.20 engine ???
Not the ESC per se - you do need the 8S pack for that motor. Have had a look around forums and these do need HV. Unfortunately the HV ESC's are never cheap. But bearing in mind, this is akin to a 20cc IC motor and not going to like 22volts at all. Some even go to 10S packs for extra umph!!!
OK here's an update on the Motor vs ESC... but 1st . WTWUK i only want to run this on 6s 22.2v because i don't want to run 8s & don't want anymore weight up front than necessary by using 8s or 2 x 4s batteries & I already have 6s batteries from a mate given to me ... I have now bought a Turnigy Plush 80amp ESC from HK & installed it & now the squealing problem has stopped .. Ive checked it wit 3 different props being all wooden 19x10, 20x10 & 20x12 & now problems all are under the max draw of the motor/esc combination 19x10 drawing max 48amp * WOT, up to 20x12 58amp * WOT. 19x10 max rpm is 5200 & 20x12 is 4900 & not heat build up from either battery, Motor or ESC. So if anyone else needs or wants to run the motor on 6s battery you can safely but a Turnigy Plush 80amp ESC. BTW i did reprogram the esc with a card to change the timing from low to medium to high & the motor did squeal on medium & high so suggest that is using this combination in a fixed wing aircraft leave the timing setting on Low... Hope this helps some people & saves some money & confusion...
The throtle endpoints (calibrate), you do by giving full throttle on TX while turning on RX. When engine starts beeping, you put throttlestick back to low throttle. Then you hear beeps, indicating cell count and your god to go!
This is the manual in German for the original YGE ESC. The YEP can be programmed exactly the same way. If you want English language you should GOOGLE!
After a hard landing on my first flight with this Yep 100a es I lost 1/2 the throttle range and power. I've used the programming card to set the throttle range which only moved the range to the middle of the control throws. Any ideas on what's wrong?
I don't know if you use a heli or not. I just installed mine this morning. You must know that you cannot set the throttle range with the programming card. I can tell you from the "original" YGE ESC what they write (and what I did): Set the throttle range on your TX to 100%. Connect the flying LiPos and switch the motor on (at your TX). The best way to do this is WITHOUT blades. Let the ESC reach the maximum rotor speed (it will have a little loss after reaching peak). Then switch off the motor at your TX and disconnect the flying LiPos. Turn off TX and receiver. Than switch on TX and receiver, connect the flying LiPos and set your TX to appr. 40%. This should result in a lower than maximum speed. Then adjust the rotor speed with your TX to the corrrect percentag so that the headspeed is correct. How should the ESC learn the miniumum / maximum gas range from the prog card? You need to this "by hand" (as desribed. If you still need help try to download the manual from the website of YGE - it is exactly the same.
I just got my second Yep 100A esc in the mail and soldered the connectors. I hooked it up and I still have the same problem of not having the full throttle range. I started to try to fix it by pluging in the lipos with the radio already on at 100% throttle. Now it just gives the lost signal beep and will sometimes to a 1 second burst of motor and that's it. I connected it to two different radios. I've got to figure this out and then re-sell the extra ESC I just got.
The ESCs can't both be bad with the same problem, I've got to be doing something wrong. Thanks for hte help oldvinyll and Obertoni, I'll keep figiting with it but for now my problem isn't solved.
My problem was entirely my fault. Now I have two perfectly fine ESC's. I finally figured out that you have to set the throttle range via the transmitter (see files) and include trims for full and off. And you have to use the programming card to get it off Heli-medium start. It was simple after I figured out the file is all I needed to follow. Thanks for all the help everyone!
Is the internal BEC in this ESC strong enough to use on a stock Trex 550 with 600ms motor and stock Align 6XX servos and FBL controller?
If not will it work better with a Trex 500 with Futaba 9650 servos with an MKS 8910 on the tail with Turnigy Typhoon motor and Futaba Gy520?
For security you can use a buffer battery. For example: 4 x Eneloop NiMH 1,2 V = 4,8 V in a battery hoilder like 4 x AA Battery Holder (Rx Pack).
Connect it with a switch to a free Port on your RX or use an Y Cable. The ESC holds a half-full state of charge of your NiMH battery. Be sure that your Battery is always at least in this state when you start.
So you can also check your RX and servos in your Heli without connecting the main battery.
Is there a video or picture of how to connect the prog card 2? There are two ports on the card. Which is which? Should I power the card with a 4.8v nmh battery? Can I conntect the battery to the card? Confused! I looked at a YGE video, but it is different. It has two wires coming out the the controller. Confused!
The prog card has 2 3 in connectors. under the pins you cn see des description. you need to connect the cable to the pins labeled with rx and the other side to your rx for setting the top and full speed signal. the cable from the esc connect to the pins labeled with esc.
the continuos amperage is 6 A .....
For some reason, when I power this esc up via a 4s battery, there are no lights on it, it seems completely dead. But when I plug it into the programming card, it lights up and I am able to programme the options.. And it lights up and beeps.
But when I disconnect red wire and pug it into the rx, which is powered by an external bec, the esc is dead, flight battery plugged into esc as well
Here is a video demonstrating rx plugged into this yep esc, and no activity, and then showing the same rx plugged into a known working esc.
il faut enlever le rouge sur le cordon de l escape qui vas sur votre rx car autrement vous avec ali separee et selle du escape donc gros probleme..il suffit de detacher le rouge de ubec de l escape et de faire un bouchon avec un retractable, et le tour et jouer
At the moment, no Programming-Card is available. I want to programm the ESC therefore via transmitter. Is the "ICE(Helidrive) manual" from the "FILES" an appropriate manual to use? Does the programm-logic on the ESC correspond with this manual?!?
I'm using this with a HK Donkey ST4010-820KV motor and a Turnigy 2200mah 25c battery. This setup worked well and lifted my ~1kg cool ghoul with no problem. After charging the battery and powering up, we noticed a significant decrease in power. We changed nothing, it still doesn't have the same power with an identical battery. Do you have any insight on this? Is there a setting on this speed control that may kick in and stay on if the battery drains too low? I really appreciate any help!
Have you tried setting the high and low throttle range on it?
Check the files section here for the instructions. Alternatively if you have the program card use that.
Only thing I can think of that might be the problem.
It only increases power to 60% of the throttle control throw so it very well could be the throttle settings. The programing card didn't come with the extra cable used to set the throttle. Do you know if that cable is just a simple servo extension equivalent (I have plenty of those)?
I got the cable and programmed the throttle. The throttle range moved towards the middle of the control throw. The power has not returned. I tried it on a different motor and had the same problem. Any other ideas on how to get the power back or what's wrong with it?
It is used mainly for F3A 'pattern' flying, so if you din't have one, no need for it.
However, out of three of these I have had, one died and only ever went ad high as 55A on 4S and a brand new one I connected up today is dead as a doornail.
Not sure about the reliability now.
Well ... Before I removed my terminals and packed this one up to return it, I gave it one more chance. Lo and behold beeps from my motor! Worked fine! Shut throttle, switched everything off. Reconnected ... no beeps but servos still working fine. Damn. I decided to have a real good look at the thing with an eyeglass and found one dry solder joint on one of the components. Flapped the heatshrink back, resoldered the leg - sorted! Works fine every time.
Ran it up to 115A for ten seconds half a dozen times to try to kill it - and it is flawless.
Faith now 95% restored!
Yes I had this esc on a align 500 and the soft start never worked properly. about 4 weeks later it stopped working all together. Sounds like when you get a good one they are fine. I replaced it with align 70amp esc However you can buy 3 of the yep esc for the price of one align.
Just fitted this to my HK500 and I'm very happy with it's performance. The slow, smooth startup is the best I've seen. Throttle response is also smooth right through the range. Very easy to program with the (recommended) programming card. I am useing a 6s 3000ma battery and the esc is barely warm to the touch after flight. Full 5 stars on all aspects.

I just tested the internal BEC, most a weak point of ESC. Its the best I´ve seen. Constantly 5A, 6A it becomes hot, and the most important - more than 10A for less than 1 sec before it switch down. I will use it in a 600 FBL, I´ve no worries to use it.

Very good ESC. Use it in a 69mm F-16 with Wemo/HET 2w-18. Far away from max spec. - only 55A. First i had problems to switch to plane startup mode - so
i fly with soft heli startup - it takes 5 - 10 seconds to get the throttle increase to
power output - was funny and sounds great but was not very usefull. after changing extention cable on prog-interface the prog card works and i was able to
change to plane startup mode. buying the prog-card is a very good idea.
bought the 80A variant too, but not used until now ....

Oh this esc is just absolutely fantastic, awesome resolution and the spool up has to be seen to be believed.
I normally only buy Castle esc's but franky those days are gone I will be ditching the castle's in favour of these. absolutely astonishing feature set, for the price.
check this vid of my trex 600 on it's maiden flight powered by zippy 5000 6S 30C cells and the helidrive 100A esc.
they will strip the link so just put this together..
