thanks Guys.. I just downloaded this beta release, did some brief testing, I am already liking it, and the CGS looks good, lot of new features., I have been using CC3d nearly 3yrs, many OP and LP versions, Quads and helis ranging fm 450 to 600, I will be doing lot of testing with this release within next few months, however one problem though, I could not get the I2C to lit up, GPS MAG config, any suggestions...
