Subject: [LML] Elevator trim tab
My Elev. trimtab does not have enough authoroty during landing configuration.
I have a Lancair 360 with 390X engine, long engine mount, MKII tail and no original trim spring system installed.
My Trimtab is 4" smaller than the manual says. My CofG at MTOW is about in the middle.
On long final with full trim up I need to pull about 1kg to keep a stable descend.
Would it help to add the Trim spring system or should I increase the size of the trim tab, or both together?
The reason of making the trimtab smaller was following: Many Lancairpilots told me that the elev trim is too agressive.
It would be better to change the speed of the servo. Is there an easy way to make the mac servo move slower?
