yes, use good bb/mg servos like the hi-tec 424bbmg or eq, using one always sets you up with equalizing problems and many more problems in flight. we have over time had many problems with uneq tail so we modify all our bigger planes with servos in tail on our small cap(sc61engine) we have just fitted two hi-tec 81mg servos the cap had problems even at fast takeoff, now its great even on very tight loops etc,
your radio is great for this not so,
ps. make sure to have one control arm up other down if you use a y-connector also eq lenths of arm retains same output, unless your radio has a reverse function for each servo then with epa equalize
