I tend to agree with Rob on this one.  I often ri= de with a friend with a Mooney that has a vernier throttle.  I sometim= es find myself thinking "come on, hurry up" when he is spinning the throttl= e knob.  Especially on landing one sometimes must make significant pow= er changes and to have to hang on to the knob with the button pushed in is = awkward.

Dan -
Two issues in my mind with a vernier throttle:

1)  I take= s a little more effort to push the button in and move the control.  Th= rottle changes happen so often that pushing the button is too much extra wo= rk.  The friction lock holds it in place, yet is easily "disengaged" b= y pushing harder.  I would also hate to need power fast and not have m= y thumb on the button.  In this sense, having a friction lock rather t= han a vernier is a safety thing, at least to me.  The changes to the p= rop and mixture are far less frequent and have less severe consequences if = a change does not happen immediately.

2)  We (at least I) gener= ally "fine tune" prop and mixture and find screwing the knob in for minor a= djustments is handy.  Not so with the throttle -- big changes are more= typical.

That's my two cents.  I would not have an airplane with a vernier throttle, and I would also not have on= e without a friction lock on the throttle.  I prefer verniers for prop= and mixture but could live with anything that can be locked at its current= setting.

From what I can tell,= Lancair typically sells vernier mixture and prop control cables but sells&= nbsp;friction lock cables for throttle.  Why not use a vernier co= ntrol for the throttle?  Is there a down side to this other than cost?=
