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 or iOS device 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

False advertising

Apr 21, 2021

Similar to what another user has stated, the product does NOT include a reversing function, as is clearly stated under the product description, with the default setting of "Reversing - OFF". The reversing function is for a completely different version of this product. This is straight-up lying about the product. Unfortunately, I purchased the product before being able to see that review of the product. Had I only known before...

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...
