Your DJI O4 Lite Has Tunnel Vision. Here's The Fix.

DJI, in their infinite wisdom, shipped the O4 Lite with a field of view best described as 'tunnel vision'. It seems they shaved off a few grams by removing your peripheral vision. Clever. If you're tired of flying with blinkers on, you have two ways to fix it. Nick Burns put them both to the test so you wouldn't have to.

First up is the HappyModel FOV Extender: a simple, slide-on bit of plastic that widens the view without any fuss. It’s cheap, light, and doesn’t anger the DJI software gods. Then there's the FlyWoo Wide Camera, a full replacement offering an even broader perspective. The catch? It comes with a permanent, rather shouty red 'calibration error' on your screen—a constant reminder that you dared to improve your own hardware.

Your decision is one of convenience versus commitment. The HappyModel is the low-risk choice for those who value a clean OSD. The FlyWoo is for pilots who crave the widest view and can ignore a persistent red warning. If you're still undecided, you can read our painfully detailed analysis or see the difference for yourself in Nick's breakdown below.
