Time will tell…
"I would give this a full five stars but I found it difficult to find any manufacture firmware to roll back to earlier versions of BF. Usually you need those with these integrated SPI ELRS receivers. I found that it fit well in the Metor65 frame. I’m running it on BF 4.4 and followed Ciotti’s suggestion on setting up the virtual amp reading. So on BF 4.4 really easy to setup the ELRS and connect my radio. I’m still trying to get it tuned but so far my whoop not staying up in the air before the battery is depleted as well as a Happy Model FC. Hopefully I’ll get it figured out because I like the idea of a better made FC."
