I'm about to make a new throttle plate control arm, and rig the spring for a default position somewhere between full open and full closed in the event of a throttle disconnect.

So the speculative question of the day is - what percent power would one like to maintain in the event of a loss of throttle control, and what butterfly position would roughly give that power?

 

Of course there is no one answer fits all - different airplane, different engine, different TB, even different pilot.  But let's just guess for a slippery airplane like a Velocity, with a 265hp NA 20B, and for a TB throat dia of about 1-3/4" for each rotor.

 

Too ambiguous?  Then I guess I'll have to wait until I fly to figure it out.
