<DIV class=plainMail>Mike I agree that we are probably stronger / more expensive servos than most<BR>of us needed.<BR>What's really needed is a tight servo that returns to center from either<BR>direction. I'm not familiar with JR stuff I still use Futaba and kind of<BR>like their standard torque S-3151 and high torque S-3152 digital servos,<BR>both in the $30 - $35 range. I don't think I would notice the difference<BR>between these and $100+ servos. As for torque, set up the linkage to use<BR>full travel (100 - 120%) on both aileron and elevator which gives near<BR>maximum torque amplification converting 40+ degrees of servo rotation to 7 -<BR>9 degrees aileron deflection and unless you are flying snaps or spins 10 -<BR>14 elevator control surface deflection. Many will likely disagree with what<BR>I've said and that's OK.<BR>How many of us really get our money's worth using the latest and greatest.<BR>Jim Hiller<BR><BR>-----Original Message-----<BR>From:
