Rudder - At the moment I am considering the 9350.

Edible... what do you think CPLR uses on his TOC !? Yup Futaba.
If its good enough for him I dare say it will do for me...

140ex is designed to go pull pull on the rudder, with a choice of DD each side on elev or use on with a pushrod if you prefer.
I will be going for one each side.

IH may do some deals on Fut servos ? worth asking when you get the kit..
