The vibe in the -22’s is from the tail.The horizontal tail front and aft stab spars need beef.and the glass needs more wrap on or near the aftest bulkhead(in the fuselage).The horizontal is giving you a harmonic vibe you feel in your butt.Wiggle the horizontal from the tip real fast but not hard.That is amplified in my opinion buy the power of the -22.That wasnt really designed well for that power.It need more strenght.My opinion as I am only jeff and I dig fat bowling chics.This is a vibe you will never get rid of unless it’s a redesign.again my own opinion.jeff drinks cheap beer.
