Nitro Engine: For longer flight duration, a nitro engine is needed.
More sophisticated battery-powered helicopters (mini or midsize) can use replaceable battery packs (keep a couple of charged batteries around!) Recent advances in lithium polymer batteries allow an impressive amount of power to be stored in a lightweight package, and RC heli makers made use of them to deliver many minutes of flight time in such a tiny package. There are four types of power used in RC helicopters: battery, nitro, gas, and turbine.īattery Power: The vast majority of RC helicopters are powered by a rechargeable battery. There are three ways to classify RC helicopters: engine, size, and sophistication. Yes, it's that small, and yes, it's a full 6 CH bird. Here's the WLToys V922 next to a can of 12 oz Pepsi.
