I stil ahven't cleaned it off... but it's strange... it's like the covering is pourous. The oil wipes off all the other covering fine, just not the yellow stuff.

Got 3 more flights today, doing IMAC trimming and the Sportsman sequence... the Panzl makes it easy... might have to move up to keep it interesting.

I ran through a trimming program... thrust is perfect, elevator alignment perfect, lateral balance is good, needs some negative differential with right aileron only, downlines are straight... what's supposed to take 50-70 flights might be done in 10!

Best of all... I just finished the 5th gallon on the motor... I have some H1R sitting here waiting to be burned... time to awaken the beast!
