RE: Top Flite DC-3 or any person who has a twin and take off issues.
One way to help this is to. Drive the rudder and tail wheel from different servos. You mix them into the same channel then whe you are lined up on the runway cut off the tail wheel so you only stays straight. Now you are free to use full right rudder from the beginning of the take off run without over steering with the tial wheel. Also adding power slowly to allow speed to build up also helps...
