Three labels, three very different shopping lists. Here's exactly what each one includes, what you still need to buy, and which one belongs in your first order.
RTF (Ready to Fly) includes the plane, transmitter, battery, and charger — everything needed to fly out of the box. BNF (Bind and Fly) includes the plane with a receiver installed but requires a compatible transmitter you supply separately. PNP (Plug and Play) includes the airframe with motor and servos — no receiver, transmitter, battery, or charger. Beginners should always choose RTF.
Before you buy an RC plane, you'll see RTF, BNF, and PNP on virtually every product listing. These aren't brand names or quality tiers — they're kit completion levels. The label tells you what the manufacturer put in the box, and by extension, what you still need to source yourself before the plane can fly.
Getting this wrong is the most common first-time buyer mistake. A BNF plane shipped to someone without a compatible transmitter doesn't fly on day one — and the transmitter isn't a $15 afterthought.
RTF is the only format where a beginner can open the box, follow the manual, and be airborne the same day. The included transmitter is pre-bound to the receiver at the factory. The only common upgrade worth making on day one is a proper LiPo balance charger — the USB charger most RTF kits include is slow and won't serve you well once you're flying regularly.
BNF makes sense for pilots who already own a compatible transmitter and want to add a second plane without buying another radio. The receiver is installed and configured — you bind it to your existing transmitter using the manufacturer's bind procedure (typically a button hold on power-up), and you're flying.
Transmitter compatibility is not universal. Most BNF planes from Horizon Hobby (E-flite, HobbyZone) use Spektrum DSM2/DSMX and bind to any compatible Spektrum radio — including the Spektrum DX6e. FrSky BNF aircraft require an FrSky-protocol radio. Always confirm the protocol before ordering.
PNP (also called ARF — Almost Ready to Fly — by some manufacturers) is for experienced pilots building custom setups with specific receiver and transmitter preferences. You source the receiver, bind it to your radio, mount it in the airframe, and route the connections. There is no plug-and-play receiver — "plug" refers to the servo and ESC connectors, not a receiver.
Not appropriate for beginners. No exceptions.
| Your Situation | Right Choice | Why |
|---|---|---|
| First RC plane — no transmitter, no charger | RTF | Everything included. Fly day one. No compatibility research required. |
| Already own a Spektrum DSM2/DSMX transmitter | BNF | Skip the transmitter cost, bind to your existing radio, save $40–$80. |
| Already own an FrSky transmitter | BNF (FrSky) | Filter specifically for FrSky-protocol BNF aircraft (D8/D16 receiver). |
| Building a custom setup with specific electronics | PNP | You choose the receiver and bind to any protocol. For experienced pilots only. |
