Trimming question<BR><BR></FONT></DIV>
<DIV>Ken,</DIV>
<DIV>Not always. In level flight the neg incidence will require up trim. In KE
flight, the tail has an increased weighting in the balance of forces and this
uptrim can be more than needed.</DIV>

I guess you can rule out <BR>> >> C.G. <BR>> >> because if
anything it should pull to the belly considering how it's <BR>> >>
trimmed <BR>> >> to fly level upright and inverted. I haven't flown

<BR>> >> look for if I get my hands on it to try and help him?
