question is, with my 9 cap, i see people who use flaps, but they go down real slow, how do i set my radio up to do that or is it some special servo or what do i need to do. Thanks

Many people will most likely be using the Servo Slow option on the Throttle servo for this. You can recreate this by having your flaps in channel 8 and following the FAQ below.
