RE: Whats the rudder for!!! ?
I would have to ask , How does one fly with out rudder ? I guess you could fly without rudder but control of your plane would bevery limited . Have you ever seen a person landing and the wings are rocking up and down, with the plane bobbing all over the place ? Their not using rudder. Or when you have a crosswind on landing , the guys that fly with rudder , can land the plane on the runway ,the ones that dont use rudder ,usually end up landing into the wind across the runway , which can be fun to watch ,as they do not really have control of the plane.
Learn to use your rudder and you well be a much better pilot for it.
I cannot recommend a new plane for you , as I dont fly electrics , but I`m sure there are many people on RCU that can hep you with that. Good luck and get to know your rudder. lol
