We are now proud to offer our Hobbyking YEP ESC series. With helicopter and airplane specific programming options such as a super smooth soft start, fixed RPM mode (governor mode) and ultra-high resolution, you won't find a better ESC on the market today!

The 7A YEP is just a scant .7grams and is perfect for micro brushless multi-rotor applications and F3P competition.

We have tested these units on our own Helicopters Quad-Copters and Micros 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.

• 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)
• 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    
• Adjustable motor timing from 0° to 30° or Automatic timing 
• Motor reversing from ESC (no need to change ESC/motor wires) 
• Throttle signal lose protection. If the signal is lost for 3 seconds, the power will automatically cutoff.  
• Safe power-on. (Motor will not start until throttle is returned to lowest position) 

***This ESC comes with wires installed, there is a no wire version as well***

Max Cont Current: 7A
Max Burst Current: 10A for 10 seconds
Input Voltage: 1-2 cells li-XX or 3-6 Ni-MH/Ni-Cd battery

Comes set up for a helicopter, so if you install it on a plane without programming it doesn't work well. The programming card is slick and easy to use. The video on YouTube is a real help - watch it a couple of times. I'm flying it on a Twisted Hobbies Clik with no problems.
This little ESC is very nice and lightweight. It didn't work correctly at first but after programming it everything is perfect.
The manual that was in the files tab was not the correct one for this ESC, so you can't program it following those instructions. LUCKILY I found out that the software is the same as on YGE esc's. I also found a matching manual and used it to program the ESC using my Transmitter!
I uploaded the correct manual into the FILES tab, it's called 'YEP 7A manual (YGE)'. Use it and your esc will work perfectly.
I do recomend this ESC!
The yep programming card PRODUCT ID: 355000020 does NOT work with this product. The manual in the files tab does not correspond to this product. To get the correct manual search for YGE 7E ESC on google. The specifications on this hobbyking product page are WRONG. The firmware is really bad and provides very little programming options. You can't even change spinning directions. The solderpads for flashing new firmware are so tiny and bad placed that you need expert skills and equipment to flash or update the firmware. My advice to Hobbyking if they want to make a 4star product : "ship this esc with SimonK or BLHELI firmware"
very small and light, I use 2 Diods to drop the voltage to the rx, for me the YEP esc are the best you can get here at the moment -03/2014
Nicely made copy of the YGE ESC. Program card works well on this ESC. Tested several motors on this ESC so far, with many different settings. All inrunners I tested (Turnigy XK-1222, 1015, 1220, 1230) start perfectly, some outrunners also work fine (M5, C05M). But some of my motors (e.g. Spin 16300, HP05s) do not start; tried nearly everything with program card, but no success so far. Do not know the reason, because those motors work very well with XP-7A and XP-12A speedcontrollers.
2.05g with wires.
That is very light and small.
Nice job!
I try to modify a 200g twin prop model.
Hopefully it works out fin...
Programming mode without card would be nice.
