This document has some useful info regarding weights, CoG limits, operating speeds etc. Generally the info within the TAD will have been checked by a thorough flight test program performed on the first completed example of the type to be completed. For the 601XL see http://www.lightaircraftassociation.co.uk/engineering/TADs/162B%20ZENAIR%20CH601-XL.pdf where theCoG range is given as 300 to 520 mm aft of datum (datum is leading edge). I hope that this is useful info. Andrew. -------- A good way through building a 601UL with 912UL. Still flying Rans S6 with 503.

In the end I found out, from the UK agents, that all you need is a spring that will apply about 6 - 10 lbs of back pressure on the stick when the flap is lowered.

It is pretty much useless. I was curious, because I had never heard of an "elevator bias spring".? Now that I know what it is, I know I don't need one.
