I am setting up my Blade 550. It has a Frsky GR8 RX and a Spirit 3 FBC. Channel 1-3 servos go one way at the normal speed, but are very slow going the other when using the TX. When manipulating the FBC, they operate normal. The slow settings for the three channels on the TX are all set at 0.0s. I do not have any mixes or curves. Channel 4 works fine. Thoughts?

BTW...I am using PWM wiring as I have not yet figured out how to do it via FBUS. The servos work normally plugged into RX. The problem occurs when going through the FBC.
