vernier throttle upgrade

[Vref]

Anybody has experience if the M20J can be upgraded with this type of throttle? Partnumber, manufacturer.

Personally I like to twiste for fine adjustements, it seems also that the newer Mooneys have this..? I have to replace mine anyway as the engine needs a schockloading inspection........

I believe it's possible, relatively expensive, and the Mooney factory via a MSC may be your only legal source.

BTW, love your avatar!

The quote I got from Willmar for a K was $800.

McFarlane makes a PMA'd one that can be used via a Form 337 Field Modification.  I did a similar one for my mixture control, and it was very simple.  I like it a lot.  They will put either a red mixture shaped knob, or a blue prop one, or a black throttle one.  Your mechanic needs to specify the business end terminations.  The standard length is 72", but custom links can be ordered.  Price is very good.  Both Vernier and push/pull with friction lock are available.

Thanks for all the info so far, will check for a quote with an MSC in europe, we need almost for every screw an EASA form1 (like FAA 8130...)...;-((....

See if you can try one before you have it installed. They are great for cruise adjustments but can complicate the "feel" of the throttle while landing. I havent used one much but it felt uncomfortable while landing.

Is there someone with more experiance using one that can comment. The few times I have flown with one just did not feel right.

I fly an Rmodel for some people and about the only thing i HATE is the vernier throttle. The owner of the plane has real trouble slowing the plane down as the vernier throotle feels like it is full at idle but the engine is still producing a small amount of power. Not good as the plane will really eat up the runway and as we know " ITS NOT NICE TO LAND A MOONEY BEFORE IT'S TIME!"

So you have to twist the throttle in order to adjust it...all the time!!!???  That makes no sense.  Can't think of a single fighter plane in modern history that has a throttle like that.

[Rustler]

You do not have to "twist" the throttle all the time. Exactly as the mixture and prop controls, the vernier throttle has a center button which, when depressed, allows you to use the control exactly like it was "straight-through", rather than vernier.

Still seems silly huh?

You may really appreciate it if you wind up with a 231 w/o autowaste gate and want to precisely control the MP.

I have a vernier throttle on my Taifun aircraft and I can only promote it. It allows a much finer throttle setting in combination with the RPM setting. Btw if you have an electric CS prop from MT the rpm setting is a potentiometer knob....You need to get used to it, but once you mastered it the usage is very intiutive...And if quick response is required you still can yank it in or out...Btw a motorglider you need to get the final speed right also otherwise you keep on flying for ever...;-)). But hey, I am getting a mooney fan know..;-)

The coolest thing about verniers....

Throttle: when you want to add just a little power on final.  You can put in a 1/2 twist and then take it right back out.  You can make the smoothest landings ever, under changing conditions. 

Mixture control: smoothly find peak by twisting at a nice constant rate. (it may take a few rotations).

Prop: No value for me, set at 2500 and left there.  If I had a digital tach and wanted and exact setting vernier would be the way to go.

For major adjustments, they are all push pull like the M20C.  (example: Full power for take-off or go around)

Verniers: Like GPS, not required, but sure are nice to have..

I only can confirm, last week did a wheely with my aircraft nose wheel off the ground and taxi..just below the stall speed would be difficult to master without a vernier throttle on  a large wing motorglider. Turning gives a perfect fine thrust control..;-). If possible I would modify on my M20J

"Throttle: when you want to add just a little power on final.  You can put in a 1/2 twist and then take it right back out.  You can make the smoothest landings ever, under changing conditions."

For me, and this is just me, it is much quicker and easier to get the immediate throttle response with the standard push/pull throttle style than by either twisting or punching the knob and then push/pull with the vernier.   Possibley I am throttle challenged here and just haven't been diagnosed yet.

I have never flown with a vernier throttle and never missed it. If I want to increase power a little I have my index finger on the panel and apply little pressure on the power lever through the heel of my hand or to reduce power I apply more pressure on the index finger. Works great even in very bumpy conditions, you just have to set the friction control right. And if I need full power I don't have to play around with the center knob. For mixture and prop I don't want to miss it for sure.

Vref: Before you spent a lot of money on things you might not need afterwards, try it out for a couple of hours, if you still want it you can install it then. Before I bought my Mooney I used to fly PA28's and didn't like the push/pull controls. After 1-2 hours in the Mooney I loved them.

My M20B is the first plane I have flown with vernier throttle and I don't like it. She also has a push pull mixture control that I don't care much for, makes it harder to fine tune. Perhaps I could just swap the controls...

thats my 2cents

OK Guys, thanks for the feedback. As mentioned I 've flown both and as such Its not the most important thing on enjoying a mooney. But hey it shows we all have our nitty gritty stuff we can discuss about...;-). Currently I am more worried about the outcome of my bent prop and the  cranck-shaft it was connected too ......;-))
