OlliW, you rock my friend! What you just did is greatly simplify my latest mod by eliminating the DD mixer/G110 combo and giving me much greater versatility by eliminating the piezo. Thank you bro! I just posted this new build of mine pictured below, so now it looks like I may have to spend some time behind my soldering iron this next week doing your beautiful mod! If you weren't a guy I would fly over and kiss you bro!
This is huge, just huge, I have the GA-250 and was trying to integrate it into the build. This dumps weight, eliminates components, and works great in confined spaces. KJ, if you are seeing this, this mod answers the problem with getting a brushless mod into your small walkera.
Nicely done Olli, nicely done!
