If everything works with the battery in ch6 but nothing works with the battery in ch3 then you simply have a bad connection between battery plug and RX.
All the +ve and -ve pins are connected together inside the RX so it makes no difference which ch you plug the battery into. This is done deliberately by the manufacturers.
As you're just testing, plug the battery into ch5 (gyro gain) and put servos on ch3 and ch6. That will let you test out the throttle/pitch mixing.
If the servos move then go to your manual to read up on throttle and pitch curves. If they still don't move, take the radio back to where you bought it.

Yeah I Kinda figured it didnt matter where the battery went, not really that different from surface radios..So I tried what you suggested and put power to ch 5 and servos in 3 and 6..channel 3 still moves with stick input but I am getting nothing from 6..could it be a bad rx..I cant find anyhing in my manual about this particular problem..I really appreciate all the help and advice Karyn
