On a new plane I'm buying it comes with (2)8411 on elevators,(4) 8411 on alirons, and (2) 4721 on rudder. I want the rudder to have 8411's on it,so can I put on the right wing panel (1) 8411 and (1) 4721 and on the left (1) 8411 and (1) 4721?? And the (2) 8411 from the wing onto the rudder.

Thanks

I wouldn't mix different model # servos on the same control surface. I would put the two 4721's on the elevators if it were me.

Why do you want the 8411's on the rudder?

P.S my friend Joey Hamilton told me I can't do that the 8411 would kill the 4721.

Yep, he's telling you exactly right. I'd always gang like servos. Even then you will have to make sure all your mechanical linkages are alike to avoid the servos fighting each other. The JR Matchbox would make this easier.
