Been flying helis for a few years and used to buying digital and expensive servos, but now I have purchased a kadet senior with a santo .91 engine and mods already done to plane. Has flaps and I need some advice on servos, can a basic servo work fine or should I buy digital ones with karbonite gears, I also use a dx8 radio and would like to take advantage of the high resolution with digital servos offer. But I don't want overkill either. What's a reliable airplane servo.
