Usmile Beitian Dual Module BN-880 GPS Module with Built-in HMC5883L Compass for Apm pixhawk NAZE32 CX-20 Walkera QR X350 PRO and Other Mid-Sized Quad

these are great put one on my cx20 and one on my qr x350 pro.cx20 had satellite lock inside my home never had that before qr x350 pro had 17 satellites locked in normally 8 or 9 x350 pro was rock solid in 20 mph wind

This works very well on my cx 20 quad....This gps module locks in , in under 20 seconds....A whole lot faster than the one that came in my cx 20....This is a VERY GOOD upgrade for the cx 20.......

Worked with my f3 flight controller for my fixed wing project, didn't have to use ucenter

I've had 5 GPS units for small copters. This one is twice the size and never worked.

Best upgrade for your QR X350 Pro. A HUGE upgrade over the stock GPS Module.

Did not come with cables as pictured.

Worked great gave me more sats. and made the quad more stable..easy to install..

Amazing! With my stock gps i couldn't get any gps signal inside my apartment, now i can get 7-8 inside home.Im guessing on a open Field.I'm completely satisfied.
