me by Bruce Tharpe (thanks to Sean). Sorry Jim, not enough motivation to use your method after the above results. Thanks guys! Will let you know how the maiden flight goes.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Helvetica",sans-serif;color:#333333">The control throws at 8 degrees and 10 degrees are a good start for the aileron and elevator. The CG at 1/3rd back from the leading edge at the fuse is way to far forward for
a start. That would make it too tail heavy which would be a challenge. Try 45% back from the leading edge and it might need to go more than that after some trim flights. Some of the old pattern planes ended up around 50% to 55% from the leading edge.
