Last night, I checked to see how much the trim for straight and level flight changed as a result of the weight increase.
It turns out there were a few surprising differences.
I set up a rather unusual test:
Very often on a CFS aircraft, if the balance on the landing gear, contact points, or spring rates are not in harmony, the aeroplane will vibrate or wiggle a little even when nothing is happening.
To test this, I leave the aeroplane loaded but inactive for a few hours and see if it has moved noticeably from where it started.
This aeroplane was left overnight and does not appear to have moved.
- Ivan.
