Super clean stack for micro builds. The built-in ELRS saves a lot of space and wiring. Installed it on a 3.5" freestyle and everything worked out of the box.

Perfect for my sub-250g long range build. The built-in ELRS saves so much space and weight. I had some questions about the TXCO version and support replied pretty fast. Solid quality as usual from Flywoo.
