In this video, I compared a few ELRS receivers to see which one is the best choice for use on whoops. The three receivers I compared are the Happymodel EP2, a Happymodel AIO flight controller with ELRS, and the (new) BetaFPV ELRS Lite receiver flat antenna variant.
For the test, I installed each receiver in a whoop and flew them all on the same path in an urban flying location at a nearby school. I compared the performance of the receivers at several points to see how these three stacked up against each other. Interesting results to be sure. Check it out and comment on the video with your thoughts!
