Those of you using the Infinity sticks, another suggestion for both
runaway trim as well as accidental trimming (such as David Jones
reported) would be to wire the red trigger (normally ptt) as your trim
activate (relocate your ptt to the momentary button to the right of the
trim hat)  Now the trim won't work unless you are depressing the trigger
at the same time.  Also prevents accidental open mike as you are flaring
to land.  Anyone interested in this circuit, email me and I'll fax you a
diagram.  I also agree with putting a switch on the panel which removes power from
the trim servos like Skip Slater did.  Those that have the Trim System
from Lancair Avionics already have a switch (it is on the indicator
itself).  All others, it is easy to interrupt the system with a simple
switch on the panel.
