Just tried to calibrate my newly acquired Mamba Max with my KO EX-10 Helios. Tried all sorts, pulled it back to FW V1.21, reversed throttle channel, increased EPA on both the throttle and brake to 150%, all to no avail.....I turn it on with full throttle held on the TX, MM then flashes green and then we get no further than this

Any news Castle guys? Sadly I don't have another radio to try
