I have no personal experience with this, but it looks to be good. If you have every played with an Arduino (a programmable microcontroller), this might be the radio for you. Motors Electric motors now rival internal-combustion motors for power and are much simpler to work with. They don舗t need gas, don舗t leave a sticky residue, and are utterly reliable. I use ones that generate lots of thrust at low airspeeds, which means swinging a 9- or 10-inch prop for their size. There is no standardization around motors that make it easy to shop.

You also have to factor in how the charger is going to be powered舒choices are alternating-current (ac) wall power (110/220 volts) or 12- to 17-volt direct current (dc) provided by a car battery or ac power supply. Chargers are the one place where the capacity of the charger is tightly linked to price. If you are dedicated to doing this project for around $150, then the charger will be $11 and will take between 2 and 3 hours to charge a battery. A more expensive charger at $45 will charge in 20 minutes.

Visit the Brooklyn Aerodrome website to see how we got this to work. Be aware that lithium-iron-polymer (LiFePo) and lithium-iron (LiFe) batteries are now being sold that look very much like LiPo batteries but differ in a few ways. 4 volts for LiPo), so if you go with these, be sure to go on the higher end of kilovolt ratings for the motor舒1,800 kilovolts is about right舒and consider using a 10-inch prop where I have been recommending a 9-inch prop. These batteries also will require a charger that is designed for them.
