theres not much in the way of budget servos...for a heli that size.......
your goona pay $20-$30 a piece....
servos like anypart of heli...you dont wanna skimp on quality.....
it would suck to crash a heli beacuse of a cheap servo failure.
futaba s3010.....great servos for a good price. around $25 a piece.
they do my raptor 50 real good......
