HobbyKing Turnigy Multistar MultiRotor ESCs

New HobbyKing Turnigy Multistar MultiRotor series ESCs

Turnigy Multistar 10 Amp Multi-rotor Brushless ESC 2-3S

Turnigy Multistar 15 Amp Multi-rotor Brushless ESC 2-3S

Turnigy Multistar 20 Amp Multi-rotor Brushless ESC 2-4S

Turnigy Multistar 30 Amp Multi-rotor Brushless ESC 2-4S

Turnigy Multistar 45 Amp Multi-rotor Brushless ESC 2-6S

Introducing the brand new range of Turnigy Multistar ESC's!
These brushless speed controllers are primarily intended for use in Multi-rotor aircraft and are the key element to our new Modular Multi-rotor power systems.
This series of ESC's features a very smooth, linear throttle response, without sacrificing a rapid, crisp, response to any throttle input. Safety is not forgotten with all Multistar Esc's featuring adjustable battery LVC, stalled motor (overload) protection, signal loss shut-down and safe arming.
All Multistar series ESC's come pre-terminated with bullet connectors suited to the ESC's rated power handling. This allows for plug and play convenience by simply adding the appropriate battery supply splitter (3,4 or 6 ESC) and motor lead extensions from the Multistar modular accessory line. What could be simpler?
Multistar ESC's can utilise the Multistar programming card. All Multistar ESC's feature an ATmega MCU that opens the door to customisable firmware - for those so inclined!
In total there are 5 ESC's, ranging from 10 45 amps.

Details:
Smooth and linear throttle control
Fast response to throttle input
Low-voltage cut-off
Stalled motor protection
Throttle signal lose protection
Safe power-on (throttle lockout)
Support 480Hz+ high refresh rates (up to 499hz)
Compatible with programming card

SimonK said this on the HobbyKing discussion product page:

"Hello! This board does seem to be compatible with kda.hex in my tree (github****/sim-/tgy/), which was contributed by Esden earlier in the year. It has an oscillator and programming pads, and has a TQFP ATmega8 so works with the HobbyKing ATmega socket flasher. The downsides are it's P/N and the input is inverted so it can't work with the USB linker."

One thing that caught my attention was stall/overload protection. I'm surprised most ESCs don't have that already, if HK can put it into their ESCs for $10 a pop.

I guess they pulled them after seeing all the critique in the comments section.
Could be a good thing if they've listened.
Give us some atmel based, one type fet only, opto escs with simonk's firmware (and pay him royalties) for a decent price and they're golden.

Have you actually tried any of these new ESCs or are you just trolling them like several other people seem to be already?

They might be suited for multicopters, just like other Turnigy ESC. Especially if re-flashed with a SimonK firmware. But in no shape or form are they designed to be dedicated multicopter ESC's.

Just take a look at the ESC/programmer card features and you see what I mean.

- Battery chemistry selection.
- Low voltage cut-off sensitivity.
- Cut-off type hard or soft.
- Soft start slow, medium or fast.

All airplane/helicopter specific features that has no place on a multicopter.

The f-30a are still better after flashing. But these might be good for people who want fast response rate and no flashing. But then you can just get the ones from RCTimer which are similar hardware (P/N Fet) and flashed with SimonK firmware already.
So I don't know lol.

Some people don't need to try things to figure how they behave.
It is calling engineering

I'm gonna quote you on that .\



I'm pretty sure these ESCs are one of their other ESC lines, re-covered and pre-soldered with connectors for their "modular multirotor system". I.e. these are the n00b-ESCs for the countless people that think octocopters are a great way to get into the hobby.
