<div>I have thought about using a small spring on throttle, such that if the servo loses power the spring will pull the throttle back to idle. Of course, this will only work with a coreless motor servo, and the spring will cause the servo to draw current when it normally would not, but I think the advantage is obvious.</div> <div> </div> <div>Bob R.</div> <div><BR><BR><B><I>Keith Black <tkeithblack@gmail.com></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid"> <META content="MSHTML 6.00.2800.1528" name=GENERATOR> <STYLE>v\:* { BEHAVIOR: url(#default#VML) } o\:* { BEHAVIOR: url(#default#VML) } w\:* { BEHAVIOR: url(#default#VML) } .shape { BEHAVIOR: url(#default#VML) } </STYLE> <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:SmartTagType name="place" namespaceuri="urn:schemas-microsoft-com:office:smarttags"></o:SmartTagType><o:SmartTagType
