How much do 4 rotors cost?
Prices vary based on category: replacement propellers typically cost about $5–$25 for a four-pack; four motors usually run about $60–$200 in total; ready-to-fly quadcopters with four rotors start around $150–$300 for basic models and climb higher for advanced gear.
To help readers budget, this guide breaks down the cost by component: propellers, motors, and complete drones, with typical ranges and what influences price (material, brand, compatibility, and performance).
What does “four rotors” usually refer to?
In drone terminology, four rotors most often means one of three things: a four-propeller replacement set, the four motors that drive each propeller, or a complete quadcopter that already includes four rotors. Each category carries its own price structure and considerations.
Replacement propellers (four blades)
Replacement propellers come in a range of materials and sizes. The price you pay is largely driven by material quality, brand, and model compatibility. Here are typical ranges by material and source:
- Plastic propeller sets: about $4–$15 for a four-pack; common on budget or beginner drones.
- Composite nylon propellers: about $8–$25 for a four-pack; more durable and flexible.
- Carbon fiber propellers: about $25–$60 for a four-pack; lighter and stiffer but pricier and sometimes more delicate on crashes.
- Brand-specific official propellers (e.g., DJI): typically $8–$20 for a four-pack, depending on model.
Note: Ensure you buy the correct size, pitch, and compatibility with your drone’s motor and ESC. Counterfeit or low-quality propellers can affect flight performance and safety.
Motors (the four rotors’ drive units)
The four motors powering the propellers also vary in price, with cost influenced by motor type, KV rating, and build quality. Here are typical ranges:
- Entry-level brushless motors: about $15–$30 per motor; total $60–$120 for four.
- Mid-range or high-performance motors: about $35–$60 per motor; total $140–$240 for four.
- OEM vs third-party motors: original equipment manufacturer (OEM) parts can be pricier; third-party options may offer savings but require compatibility checks.
When replacing motors, you may also need to consider new propellers, mounts, and sometimes ESC or wiring updates to ensure proper power matching and balance.
Ready-to-fly quadcopters (four rotors included)
Buying a complete quadcopter with four rotors involves a broader range of features, from basic flight stabilization to advanced camera systems. Price bands reflect build quality, sensors, and payload capabilities.
- Budget beginner quadcopters: $100–$200; limited features, basic stabilization, and often no high-end camera.
- Mid-range models: $200–$500; better stabilization, GPS, longer flight times, and improved cameras.
- Advanced prosumer models: $600–$1,500; robust builds, superior cameras, obstacle avoidance, and longer flight times.
- Professional or specialty rigs: $1,500–$3,000+; high-end cameras, modular systems, and extended support equipment.
Used, refurbished, or bundle deals can offer lower prices but come with risks like battery wear or missing accessories. Always verify battery health, warranty status, and spare parts availability before purchase.
Summary
Four rotors can cost just a few dollars when you’re buying a replacement set of propellers, or several hundred dollars when you're replacing motors, and thousands for high-end professional quadcopters. The main cost drivers are propeller material and brand, motor quality, and the overall capabilities of the drone. For most buyers, planning around the total cost of ownership—including spares, batteries, and charging gear—helps avoid surprises.
