style='font-size:12.0pt;font-family:Arial;color:black'>High vibration levels
will require more power to compensate. Yes, more torque will be
required in strong vibration environment. It is like you
have an unbalance prop. The power output is less since some is
been use by the vibration. It is difficult to explain but for sure is
there. Another example is the effect of the soft mounts. It is well
know that large gasoline planes required several servos per surface to
compensate the additional vibration. If we use soft mount (I do in 100 cc
planes) in those large planes we can reduce the number or servos per surface.
Currently I am using one servo in 100 cc plane with soft mount. I have
seen the same plane with 3 servos without the soft mount.<o:p></o:p></span></font></p>

Tommy I worried about the 3421's until I looked at the size servo's that
QQ was running on his Euphoria. He runs dual ailerons on 1 small servo. I'm
running 3421 metals on my ailerons on my new Sickle so far so good. It was
because of weight and also because I really think an E. plane can get away with
less servo. I run it on a 6volt regulated 2 cell lipo. I think everyone is in
to the security that overkill allows and that's great if your not worried about
the weight. Mike<br>
