<div>IMHO, the signal output level has nothing to do with resolution or torque. The servo either works or it does not, the torque/resolution does not change with signal amplitude. The output level is simply the logic level that the system was designed to use. This is one reason that you need to be careful when mixing servos/receivers from different companies.</div> <div> </div> <div>There is nothing wrong with using a signal booster. The pulse width is not altered, only the amplitude. It may help with long leads, especially with multiple servos. It also provides some isolation.</div> <div> </div> <div>Bob R.</div> <div><BR><BR><B><I>Anthony Romano <anthonyr105@hotmail.com></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid">Hi Fred,<BR>Am I to imply from your comments below that Futaba receivers output a lower <BR>than optimal voltage to the servos?
