HQProp 7x9 Thin Electric: The 'I Want to Go Fast' Propeller
Look at you, scrolling through propeller listings like it's a dating app. You've swiped left on the chunky bullnoses and the floppy bi-blades, and finally, you've found 'The One.' The HQProp 7x9 Thin Electric is designed for those who think air resistance is a personal insult. It's thin, it's stiff, and it has more pitch than a desperate door-to-door salesman.
Why You Actually Want It
Most props are built for 'durability' (read: they're fat and inefficient). These Thin Electric props are built for high-speed efficiency and long-range cruising. If you’re building a sleek fixed-wing or a very specific long-range quad that needs to slice through the British drizzle like a hot knife through Lurpak, this is your ticket to the clouds. Plus, they’re from HQProp, so they’re actually balanced—unlike your current life-work ratio.

In the Box
- 2x HQProp 7x9 Thin Electric CCW Propellers
- A fleeting sense of technical superiority
Compatibility
Perfect for high-torque motors on fixed-wing aircraft or specialised 7-inch long-range builds. If you try to put these on a 5-inch racing drone, please film the resulting fireball and tag us.
Highlights
- Thin Profile: Minimises drag so your battery doesn't cry as much.
- High Pitch: For when you want to turn RPM into actual forward momentum.
- HQProp Quality: Less vibration means your flight controller doesn't have a mid-flight panic attack.
Notes
These are CCW rotation. If you need CW, go find the other listing. Don't come crying to us when your plane tries to fly backwards into a hedge because you didn't check the rotation.
Disclaimer
We are not responsible for your sudden addiction to high-speed low-passes or the inevitable noise complaints from the local park rangers.
