DVR Module works very well. I have devised special mounting for Hummingbird. See my post on Facebook Tiny Whoop Brushless Group.

Although I would prefer a higher resolution like 720p or even 1080p, just having a clean, clear DVR recording free of static on my whoops is great. Relatively simple to install & operate, too.

I've done one short test flight on my 2.5" that is still in progress. The DVR works and is very small and lightweight. I did have some breakup and static in the video but was still probably a little better than recording with goggles. The connectors are tiny and don't fit any other standard camera or flight controller so I had to do some customization to get it all connected.

I really couldn’t be more impressed... and it integrates so perfectly with the Goober Canopy. It’s worth it’s weight!!! People ask me what VTX I’m using to get such an image.... haha. I’m cheating! It’s the NBD DVR!!!

I placed my order with NBD and they shipped out quickly. I was surprised how tiny the NBD DVR is. Works great!!! Can't wait to record more video's with my 75mm ductless Whoop.
