When I bought my Futaba 7C, it came with 3151 digital servos, so these are what went into my LT-40. I have just bought a Twist, and thought I'd get a flight pack with 3004 servos, put these in the LT-40 and swap the digitals into the Twist. Whats the benefit of digital servos? For an aircraft like the Twist would it be worth the time to swap the servos?

Thanks!
