Thank you all for the input on the vernier trhottle control,
both the +'s and -"s.
Wayne, Your opinion on the matter is exactly as mine. Having used a vernier
control over the past 40 years I kind of like it. Now that I have gone to LSA,
I am happy to be able to purchase one for my new coupe, which I have yet to
fly. I purchased the coupe in Nov of 07 and it is still in the shop.
Each time it leaves the hanger a new problem comes up and it never gets off
the ground. For the people who were talking about the cost of coupe ownership,
I am approaching 50% of the cost of the plane that I have yet to fly and I do
not mind it as I love my coupe. I will love it more when I get to fly it in
about three weeks.

Some time back there was a posting about having
a throttle with a vernier control an a coupe. Can anyone
tell me where I may purchase such a throttle with a
vernier control?

It's a funny thing. The man writes in and asks where he can get a vernier
throttle control for his airplane, and there are 8 responses, and not one
response even begins to answer the question that he asked!

You can buy a vernier throttle from Aircraft Spruce & Specialty. They
carry ACS Products Company throttle and mixture cables. The address for ACS
Products Company is:
ACS Products Co, Inc.
1585 Copper Drive
Lake Havasu City AZ 86403

The vernier throttle cable in my Alon is ACS P/N A970-10-0480. The
Aircraft Spruce part number was 05-08348 at the time that I ordered it. I had
to send the cable back to ACS products to have it shortened and to have a
threaded barrel put on it. ACS can modify their cables any way you want for a
reasonable price.
The matching vernier mixture control was Aircraft Spruce part number
05-08160, which is an A-070 series cable.
Your mechanic will have to figure out what paperwork is required to keep
the installation legal. Mine was installed back in the 1980's with a logbook
entry by my A&P/IA at the time. Let me know if you want any more info.
I know that you didn’t ask, but everyone else offered their opinion on the
pros and cons of vernier throttles, so I might as well add mine.
I like it. I keep my hand wrapped around the whole throttle knob. When I
want to make large adjustments I basically spueeze the knob in my hand and the
palm of my hand pushes in the button and I use my whole hand to push the knob
forward. Once you get used to it you don’t even think about it. I never screw
the throttle in or out more than one or two twists, except in the landing
pattern, where a certain numer of twists puts the RPM exactly where I want it
turning downwind to base, and base to final. For any large adjustments I just
depress the button and push the knob in or pull it out. Same hand position
either way. When making minor throttle changes, the vernier works great. At
cruise, I know exactly how much of a twist results in exactly 25 RPM, so you
can throttle up or throttle back slightly without even looking at the
tachometer.
This is just a matter of personal preference and what you get used to.
Either way works fine and either way is perfectly safe.
Just my opinion.
