Hi Guys,
I fly jets and run 1/5 scale cars. What I do is to cross some of the tips from one side to another. If you see how the servos on a steering are install in a car with turnbuckles and ball links you will not have troubles ever, the punishment that we give to those systems is the worst you can do to test a servo and the horns. So check it out and just transfer it to the jet.
