hello all,
first, sorry about my bad english,

now back to the problem,
as i wrote in the topic, i have a tail wheel in my F3a model,
I need only a little angle for the Rudder for make the "knife edge",
but the problem is that i need a big angle for the tail wheel to turn back the model after the landing,


I dont have any d\r option for the rudder in my radio controller ( only with elevator and aileron).

so, what can i do .
