I've never had a problem with either CB200 or CB400 up until now. No issues with the CB400 in my Hawker Hunter.

I only said it was PARTLY responsible, but in retrospect, why would you put a fuse on a primary flight control - if it trips you guarantee loss of control.

See the current draw profile from telemetry below;





The servo torque was well in excess of design guidelines for the surface.

Nearly 9A just before impact, while most of the flight it was 1-3A. Full flaps and the deflection of the unique tailplane flap configuration likely caused an increased elevator servo draw (MKS 777A+ - 500oz.in/ 36kg.cm) and the inability to pull out of a steepening dive just made it worse.

Going to use a MKS X8 HBL3850 servo with over 700oz.in (50kg.cm) on the elevator for next build also.
