The 9WC is an awesome radio but definitely lacking in one simple area; it has 8 proportional channels and then a 9th channel which is either on or off. You can't adjust anything on the 9th channel, so for me it is pass on that. (That is why I call it the 8 1/2 channel radio)
On my 9Z I usually put retracts on ch9 and assign it to the normal retract switch. That leaves me with 8 propo channels for the rest of the stuff. Haven't had a complex aircraft that didn't have at least one bang-bang channel (like retracts).
