I've decided yesterday that i am definately going dual servo's. The radio i am running is the new JR x2610 6 channel digital, but it doesn't have the 'ailervator' capability like the PC10x or whatever the higher model is. Is there some way you can run one servo off ya normal servo channel on the reciever, then use say the 5th channel on the reciever and somehow assign that channel to the elevator aswell?
But otherwise i did some research when i posted this the other day, and will just go grab one of them reversing 'Y' leads, as it will probably be the easiest. At least that way i know it will work. The best bit is that both servo's can be mounted on the tail of the fuselage externally

No mucking around with pushrods and what not, so i'll run some larger gauge rods so basically there will be zero flex

Thanks guys, james.
