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

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

MultiStar ESCs are are a quality speed controller at a fantastic price! Designed for simple installation and easy setup these ESCs have proven to offer excellent performance when used in Multi-rotor applications. If your starting out in Multi-rotors and need an easy to install solution that is tested and proven to work with Multi-rotor craft then these speed controllers have you covered.

These ESC's features a very smooth yet 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 (set battery type to LiXX to disable LVC), stalled motor (overload) protection, signal loss shut-down and safe arming.

All Multistar series ESC's come with bullet connectors installed that are 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?

All Multistar ESC's feature an ATmega MCU that opens the door to customizable firmware - for those so inclined! or alternatively a programming card can be used with the installed software for quick and easy setup with the pre-flashed software.

Make sure you check the BEC output voltage on these ESCs! I just had one fry my controller board it was outputting 11 volts instead of the 5.5 it is supposed to!! :(

Crawdad - thanks for this reply. Really appreciate it. I must admit, as a beginner, I do not understand what it means to use a different BEC. Here is a link to the setup I want to emulate: *******flitetest****/articles/turnigy-sk450-deadcat-
I wanted to use the specified ESC, but it is backordered. Plus, I am having trouble finding some that are already flashed with Simonk firmware, but I can probably do that on my own as there are good tutorials out that. Just having trouble ID'ing the right hardware that will not result in a fire or destroy the quadcopter. Given that the ESC is on backorder, I welcome any advice you or others have as to how this build could be modified to allow me to put all the pieces together. Thanks!!!!!

The F-20a ESC is a good choice - it's got all N channel FETs, so it's a good candidate to reflash to simonk firmware, and it's a couple of bucks less expensive. The only negative you might encounter is that the F-20a doesn't come with the connectors for power or motor. You'll need to get a pack of 3.5 mm connectors and some 4 mm heat shrink. They all have BECs in them, so you'll just want to pull the red wire out of the receiver connector on all but one of them, so they don't have a fight over who's providing power to the flight controller and receiver.

Dan, now that I think of it, the Afro series ESCs already come with the simonk firmware on them for a few bucks more. Try looking at product number 9192000131-0, it might be just what you need.

Hi - I am a beginner. I wanted to use this ESC for my first quadcopter build, however, it is backordered. Can someone suggest another, comparable ESC (20 amp)? I do not know how the OPTO version of this ESC differs from this one. Is that ok to use in place of this one? Or, is there another one that would work? Thank you!
 Crawdad 460 points
The opto version doesn't supply power to the flight controller, the standard version does. You can use a separate BEC to do the job, you just need to fit a servo Y cable on some flight controllers. Can you provide more info about your quad? What kind of flight controller are you using?
 Crawdad 460 points
You can get BECs that are separate units, like item number 9171000012 for example. You hook them up to your LiPO, and they produce the right voltage for your receiver, flight controller, servos, whatever. You can run a quadcopter with four opto ESCs in it, you just have to have a separate BEC as well to provide power to the flight controller and receiver. You need to use a Y cable to connect the BEC if you're using a KK2 controller, as you need to supply power to it through the M1 port, but you also need your first ESC plugged into that port. The solution is to plug a Y cable into the M1 port, then plug the BEC into one side of the Y and the first ESC into the other side. The nice thing about using all optos and a separate BEC is that you don't have to keep two types of spare ESCs - they're all the same.

I have these set up on a 450 quad with a Naza controller, calibrated the ESC's individually and they are working fine.
The connectors are 3.5mm, similar to the Polymax plugs and sockets. The wire is all 16 gauge and is pretty good quality. The motor leads are a bit longer than I like but it means you have plenty of length for most installs. The battery connector is also plenty long with bullet 3.5mm plugs, I cut these off because I needed to solder to a DJI power frame, if you are using a HK distro board they will plug straight in.

Good quality ESCs. I use these to drive "Turnigy D2836/8 1100KV Brushless Outrunner Motor" in my "Turnigy H.A.L. (Heavy Aerial Lift) Quadcopter Frame 585mm". I still have not seen any problems.

Have them working on a quad with Naza GPS and they work great. Naza flies better than with regular ESCs, it does not even wobble much on fast descents, which is a known Naza issue. The only thing I am not sure about is how to calibrate throttle, looks like they don't need that. HK please give us a clue if throttle calibration should be done and if so then how. Thanks!
