The Aerostar WiFi range of brushless electronic speed controllers (ESC) is designed for RC fixed wing aircraft but can also be used in helicopters. They feature super smooth startup, linear throttle response, multiple protection features, all at a fantastic price.


These AeroStar WiFi ESCs can be easily set up using the AeroStar WiFi Connect device (see ACC tab below). This device uses a WiFi connection and an APP on your android phone to configure the ESC. Otherwise, you can still use your transmitter and listening to the tones to configure the ESC.

• Adjustable startup mode for either planes or helicopters
• Safety features on power up will stop the motor if the throttle is set high
• Low voltage cut-off

• Setup via WiFi device and Android mobile APP (separate device)

Criminally mis-described

Feb 25, 2021

I wanted a reversing ESC for a seaplane. So I set the filter selecting to "reversing", "In-Stock" and "UK Warehouse" and it offered me this ESC. The description page talks about default settings including "Reversing - OFF" implying there's a reversing function, and the instructions under the FILES tab describe how to set up and operate it. But actually this ESC has NO REVERSING FUNCTION. Only the ones with "RVS" in the name have a reversing function. So once again Hobbyking mis-sells defective products, and leaves it for the poor customers to sort out the small grains of truth from the massive pile of steaming lies. If a hobbyking employee says it's a nice day then make sure you have your umbrella...

Good ESC but to use WiFi needs extra device to use.

Sep 01, 2019

A good ESC works as well as all others. The WiFi feature can only be used by purchasing an additional dongle. So don't buy this one unless you need wifi options. Others will do exactly the Same. I bought 2 of these and found out after I need extra equipment to utilise all the features. But good value in any case and they do look good and so far reliable

an good error

May 08, 2019

When I buy it, I don't realize that this esc may be programed throught my computer, but really is a good idea. You don't need have a lot of programation cards for all your esc.
