Hi Dave
i have raced wheel radio since i started in 1990 with a very basic 27am set have progressed to ko mars and 3pk futaba now .I fly planks and whirly birds on stick radios (Futaba FF9) but i am buggered if i can drive a car on them
everything happens far too fast . I dont think i will ever master a stick for cars
Peservere with wheel it is worthwhile especially if you are having flexibilty issues with your fingers .
In defence of sticks my 13 year old son can drive either wheel or stick with equal effiency
good luck dave
