7-Inch Long Range FPV Frames
7-inch FPV frames carry 7-inch props on 2806–2812 motors and are the standard platform for long range and cruising builds, where efficiency, GPS and a Li-ion or large LiPo pack matter more than agility. This page collects every 7-inch frame in our Frames range. Pick by camera system first — several frames here are cut for the DJI O4 air unit — then by arm thickness and pack bay, since a 7-inch quad carries two to three times the battery of a 5-inch.
How to choose a 7-inch frame
A 7-inch build weighs 550–900g ready to fly and cruises at low throttle for 15–40 minutes on Li-ion, so the frame is about carrying a big pack securely and keeping the GPS and antennas clear of the props.
- Arm thickness: 5–6mm arms handle the leverage of 7-inch props; thinner arms flex and vibrate.
- Camera and air unit fit: O4 Pro and O4 Lite need different mounts. Frames sold as O4 versions come with the right camera plates and a cavity for the air unit.
- Pack bay: check the top plate takes a 6S 3000mAh LiPo or a 6S2P/6S3P Li-ion pack lengthways.
- Deadcat vs true-X: DC (deadcat) geometry keeps props out of the camera view for cinematic shots; true-X is more neutral for freestyle-style flying.
What we stock

Compatibility
Motors of 2806.5–2812 stator size at roughly 1300–1500KV on 6S LiPo or Li-ion, or around 1000–1200KV on 8S, are the usual pairing; 7-inch arms are usually drilled for 16×16 and 19×19mm motor mounts, both standard for that motor class. Stacks are 30.5×30.5mm on most frames, and some add 20×20 holes for a smaller board.
Plan antenna placement early: a 7-inch frame is long enough to fit a 900MHz ELRS receiver and GPS on the rear arms or top plate, well away from the VTX.
Frequently asked questions
- What motors go on a 7-inch frame?
- 2806.5, 2807 or 2812 motors at roughly 1300–1500KV for 6S LiPo or Li-ion, or around 1000–1200KV for 8S. Most 7-inch frames take the 16×16 or 19×19mm motor bolt pattern.
- How long does a 7-inch long range drone fly?
- 15–25 minutes on a 6S 3000mAh LiPo and 30–40 minutes on a 6S2P or 6S3P 21700 Li-ion pack when cruising, depending on all-up weight and wind.
- Do I need an O4-specific frame for a DJI O4 air unit?
- Not strictly, but O4 frames come with camera mounts cut for the O4 Pro or O4 Lite camera and space for the air unit, which saves printing adapters. Other frames need a compatible mount.
