RE: Excelleron 90
dreadnaut - what ElectRick sez is right. Ya gotta do whatcha gotta do. His suggestions are very good. It's frustrating to have to do, but the end is worth the work. You will have a VERY straight airplane, if you fix it properly, and it will fly excellently.
Have not heard of anyone else with this issue (or maybe no one caught it yet)... I'll be rechecking mine here in a little bit.
TOMORROW is ST2300 first flights, folks. I've tweaked, checked, adjusted, balanced....time to see if it holds or blows up. I'll report back here, or at the NTSB.
