IF you have a 7CAP (or any other radio that wont provide a mix with trim for 2 channels) i would never use an inline or Y reverser, they are JUNK! they never remain on centre. The JR matchbox is the only way, you can link upto 4 seros together, control null zones and reverse any servo, they are brilliant.

By the way i have just discovered JR radio after using futaba for 25 years....Man that JR stuff is so easy to program and of far better quality....
