Designed for planes only, the H-KING ESC are an excellent choice for any plane requiring linear, sharp and reliable throttle response on a 20A ESC. H-KING speed controllers have strict end-of-line QC testing and are SMT (Pick-n-Place) in the same room as the through-hole soldering(wires, capacitor) and packaging is done. Improving quality and reducing contamination and inconsistencies due to transportation. The H-KING Speed Controller includes a 2A BEC (Battery Elminator Circuit) to power your receiver, there is no need to have a seperate receiver battery. The H-KING range of ESC are both economic and reliable. They are pre-setup with LiPo and auto cell detection so you can just plug it in and fly!
There are very limited programming options on this ESC. Great for small basic planes but would not reccomend for anything that requires to much in the way of fine tuning or very precise control. Hope this helps.
The size of the battery doesnt make that much difference, but a upgrade or larger prop can increase the amps required by the motor under load, therefore the esc may need to upgraded also but your motor is only rated to so many watts and once you exceed the watts you risk damage to your motor.
Love the startup tune. But then the beep every 15s when there's no throttle input is a bit annoying. There's no heatsink, so make sure there's some airflow. I gave one of these to a mate, who fried it with a battery that had an overcharged cell. The voltage wouldn't have been much above 12.6V and the thing caught on fire! So caution! Personally I prefer the SS series when they're in stock
