Regulators are not necessary in most applications and actually produce another point of failure in a power system that is already vulnerable. They should be used only in applications that really need voltage regulators.
Talk to any experienced pattern person and they will tell you that basic is good. Simple is best.
Good point - regulators are definitely for more advanced systems, and not so much for basic sport flying.
I've now got a set of competition planes with 6 digital high torque servos in each and am just switching over to a regulated system (with integrated switches, reducing connections).
