<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">The way I remember it when I started competition, it was based on control functions not channels. All classes could have throttle, Class I was rudder, Class II was rudder and elevator, and Class III was rudder, elevator and ailerons. In fact most systems used two "channels" per control function. Later on people used 4 channels on elevator. Up, down, up trim, down trim. This took two "servos". I recall that Cliff Bennett in South Bend built a rudder only plane for his son Dick that used a reed bank and servos that required two channels, that were far superior to escapement type "servos". <DIV>The good old days!</DIV><DIV>Jim</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><BR><DIV><DIV>On Aug 17, 2007, at 11:21 AM, billglaze wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"> <DIV><FONT face="Arial">Class 1, single channel. rudder only.</FONT></DIV> <DIV><FONT face="Arial">Class 2, single channel, everything you could get on it, rudder, elevator, motor.</FONT></DIV> <DIV><FONT face="Arial">Class 3, Multi channel.
