HobbyKing 30A BlueSeries Brushless Speed Controller

HobbyKing 30A BlueSeries Brushless Speed Controller

Its no “Mystery” where these ESCs are made, now they are available to you at HobbyKing prices.

Built with imported N-Channel mosFET's and an ultra fast Atmel MCU & heartbeat make this a high performance ESC with excellent sync capabilities. This ESC has a 3A BEC for solid reliable servo power.
Programmable via an R/C controller.It allows you to program all functions to fit your specific needs, which makes it efficient and user friendly.
Extremely low internal resistance
Super smooth and accurate throttle linearity
Over heat and over-load protection
Auto shut down when signal is lost or radio interference becomes severe for more than 2 seconds
Supports high RPM motors
Power arming protection (prevents the motor from accidentally running when switched ON)
New Advanced programming software
Programming features:
Brake setting (we recommend using brake for only folding props applications)
Battery type(LiPo or NiCd/NiMh)
Low voltage cutoff setting
Factory default setup restore
Timing settings (to enhance ESC efficiency and smoothness)
Soft acceleration start ups (for delicate gearbox and helicopter applications)
Governor mode(for helicopter applications)
Motor rotation( clockwise\counterclockwise)
Switching frequency
Low voltage cutoff type (power reduction orirnmediate shutdown)
Factory default settings:
Brake:  off
Battery type Detect:  LiPo with Automatic Cell
Low voltage cutoff threshold:  Medium (3.0V/65%)
Timing setup:  Automatic
Soft Acceleration Start Up:  Medium
Governor mode :  OFF
Frequency :  8kHz
Low voltage cutoff type:  Reduce power

Three Black Wire Placement To Motor. Hi all, my question is regarding the three black wires on the ESC and is there a specific motor wire, Red Black Blue, that each position on the ESC corresponds to? Thanks, SM
 Salvatore 6 points
No. The three black wires go to the motor wires in no specific order.

Thank you, thats what I thought, but wanted to make sure just in case.

Guys, the description says SBEC, yet the image says BEC - does this really have a switching BEC?
 John 1 points
you will have to disconnect the red wire from all of these after programing, as the red wire puts the full battery power on it! I smoked an RX and other 5 Volt devices! so you need an UBEC, this is a switching BEC 8khz or 16khz the manual that comes with it explains about the switching freq, but fails to mention about the voltage on the red wire!

Will this esc be able to run 6 9g servoes
 ElectricAussie 4015 points
Hi Thomas, Not all 9g servos draw the same amount of current, so you need to know the specs on the servos you choose. Example, the HK HXT900 servos are cheap and work well but they have a rep for being very power hungry for such a small package. The safest approach to avoiding overloading/overheating the BEC in this ESC is to choose servos with a stall current that is less than 600mA-700mA. It's very unlikely that all 6 servos would ever be working close to stalling, so the average current for all 6 shouldn't exceed 2A. That leaves .5A for powering the Rx and .5A safety margin before you hit the 3A limit of the BEC. This is all just my opinion, of course, but it's based on 30-plus years of flying RC planes. Cheers, EA!

hi Looking for the original firmware for this controller, someone help me?
 srepfler 1248 points
Original is locked, can not be read. After flashing with Simon use only for rotors.
 Tomasz 5 points
OK thanks for the help
 MasterB 198 points
Is there any custom that has LVC? I have a bunch of those ESCs flashed with SimonK and I want to use them with airplanes again
 srepfler 1248 points
Use battery buzzer with LCD it can beep early or use telemetry.

I put two of these in a Dynam A-10 with the stock 64mm 6 bladed edf's & a Turnigy P2627L EDF Outrunner 4200kv for 55/64mm with a turnigy 3000mAh 40c lipo. Esc's are giving out 34A at WOW & come down a little hot on hard flying but are doing the job and keeping the plane really low on weight. great price I love these blue babies, go for it. I will by buying more!!!
