7-Inch Long-Range FPV Drone Build: The Ultimate Kit Guide
Building a 7-inch FPV drone is the ultimate step for pilots looking to transition from agile freestyle to long-range exploration and “mountain surfing.” While 5-inch drones are the kings of the park, 7-inch rigs are built for efficiency, hang time, and carrying larger batteries over vast distances.
Using the structure of the Mall of Aviation 5-inch guide, here is your comprehensive guide to building a high-performance 7-inch Long-Range FPV Drone Kit.
1. The Core Components (The “Kit”)
Unlike a racing drone, every part of a 7-inch build is chosen for efficiency and vibration management.
The Frame: 7-Inch Long Range
A 7-inch frame needs to be stiff to prevent “prop wash” and resonance. Look for frames with at least 5mm or 6mm thick arms.

Flight Controller & ESC (The Stack)
Since long-range flights often involve GPS and extra sensors, a powerful Flight Controller is a must.
GEPRC TAKER F405 BLS 50A STACK is a plug-and-play stack system specially designed for DJI Air Unit. Use STM32F405 chip, ICM42688-P gyroscope, integrated 16M black box, and GEP-BLS50A-4IN1 ESC to have a more delicate hand feeling experience.
The GEPRC TAKER F405 BLS 50A STACK can be directly plugged into the DJI Air Unit, which can save the trouble of soldering. Upgrade the type-C USB connector, which greatly improves the service life of the socket and reduces the risk of poor contact. 9V 2.5A + 5V 3A dual independent BEC, more stable power supply for external devices.
Features
- Use mainstream STM32F405 chip
- Equipped with the latest 42688-P gyroscope
- 16M black box storage
- Integrated LC filter
- Upgrade type-C USB interface
- Directly plugged into the DJI Air Unit
- With GEP-BLS50A-4IN1 ESC, the flying feel is silky
- Simple and reasonable installation method, the shock absorber can make the gyroscope work very stably
- 9V 2.5A + 5V 3A dual independent BEC
The Props: 7-Inch Bi-Blades
While 5-inch drones use tri-blades for grip, 7-inch drones often use bi-blades for maximum flight time and efficiency. 
Pro-Range Propellers are robust and lightweight blades designed specifically for drones. Available in various sizes and vibrant colors, these propellers enhance a flight performance and add a stylish touch. They improve flight stability and efficiency, ensuring smooth operation during drone use.
The Pro-Range propellers are crafted from durable materials like Polycarbonate, Glass Fiber Nylon, Polycarbonate Reinforced etc, offering an ideal balance of strength and weight. With a well-designed pitch, they optimize thrust efficiency, making them perfectly suitable for variety of drones.
Features:
- Lightweight and durable
- Provides excellent balance and stability
- Suitable for various motor shafts
- Cost Efficient
VTX and Camera
For long range, signal penetration is everything.
Long-Range Essentials (Don’t Skip These!)
-
GPS Module: Absolutely mandatory. It provides “GPS Rescue” (Return to Home) if you lose your video signal.
