hi guys....i'm working on my first build, a quad with naze32 fc, 20 amp afro esc's and using a turnigy 9x and receiver. using cleanflight 1.12.1. problem is....i can't throttle the motors up through the radio. when in the receiver tab cleanflight shows changes to throttle commands given by the 9x but no motors spin up. the motors do spin when commands are given in the motors tab. i've missed something or ignored some instruction somewhere. can anyone help get me back on track. thanks...jtdrive
