Well if that's the case, I have some new in package Futaba S3004 ball bearing servos. The speed is .23 seconds on 4.8v, torque 44.4oz on 4.8, and they weigh 1.3 oz a piece. But what bothers me is it says on the back of the package, "The S3004 is suitable for model airplane and car applications, however, can not be used for gas powered helicopters." Yes, I know the Tiporare is a plane, however, if there's a limit to what you can use them in, I am concerned about there use in a 100 MPH + plane.
