Kurt,

Balance with an empty tank??? I always figured it best to balnce with a little more than a half tank to simulate the average weight of fuel in a flight. That way you'd spend the front of the flight a tad on the nose and the rear of the flight a tad on the tail. I was aiming for the magic 4" with half a tank or so. The CG on this bird travels noticeably with a changing fuel load due to the long nose. Right now I am at about 4 1/4" with a bone dry tank.

I talked to Polk today and got more squared away about the flaperons. Their radio still doesn't work as well as they claim it to but he explained the function of some of the settings so that I could wrap my brain around them a little better and now the aileron throws are set identical. The up/down differential has to be set mechanically as their electronic handling of the issue is maybe a hare short of useless.

I learned why y'all have been putting graphics on the bottom while playing with high rates and snap rolls on the second flight this past Saturday. Fortunately I stayed two mistakes high and pulled her on around without incident...just a little vertigo and butterflies [:-]. I picked up some vinyl letters at a local kraft store so I could apply a little help to keep myself oriented, I think this oughtta do it...
