NTSB Safety Alert CH 601

Here's a model report on treating home-builders like grownups.
Highlights:
Mass balancing controls - tight control wires not enough

Reduced stick force per G at higher G made worse by aft CofG

Don't push the stick hard by mistake - it may be your last.

I forgot to mention a tactic used for improving pitch stick force per G.
Where an elevator rod or wire is connected by a pulley wheel or lever
- a mass on a fore and aft lever arm from the pivot provides a turning
moment which increases with increasing g, so as to increase the reaction
to elevator control force with g. This was the tactic used on the
Spitfire, if I remember....
There's another mass that is not structural like surface balances.
