I heard that Van's would release a vernier throttle for the RV12 S-LSA pretty soon. Do you have any good info about that?
Thanks,

I have tried several weaker springs, and one set failed due to work hardening from forming a new hook after cutting down the length. I finally found a set at Home Depot that provide smooth action without creeping. FYI, the throttle cables were stiff enough to operate the carbs when the one set failed. There has been some discussion about the wisdom of replacing the springs, but I am happy with my current set up, and I found the previous failed set on preflight, not due to any rough engine or loss of power. Just passing on my operating experience. I am sure many still doubt the wisdom of going to weaker springs.
I installed the vernier throttle in N112VA (the Garmin G3X Touch airplane which I'm bringing to OSH) a few months ago. A vast, vast improvement over the standard throttle/spring arrangement.
Over my hundreds of demo flights in the RV-12, many folks have asked if there was anything I didn't like or would want to change on the 12. I always responded that the throttle was a weak area. It isn't now.
I just picked up a new SLSA and am on the long flight home. my hand and fingers are really sore from having to use the throttle with almost full friction lock on to avoid the throttle moving forward rapidly if I take my hand off for a second.
when I ordered the plane I specifically took Mitch,s suggestion about the vernier throttle. van,s usual response is " I ,s still in engineering" however they did tell me that the "new springs" were are big improvement. I didn't,t get them because the original batch had metallurgical issues and had to be sent back however I can order them when they come in .
quite frankly the throttle , for me, is a huge pains in the rear and along with the rudder pedals being non adjustable is the biggest gripe I have. I saw Vans are saying they are close to producing a mod for the pedals as well as dual screens.
BTW..the Skyview Touch with ADSB in and out is great . I also have the Seattle sectionals installed and it's nice to be able to switch. Between the Dynon chart and the sectional chart to cross check.
Two more days......
I love my S-LSA but I certainly would love it more with a vernier throttle.....might be somewhat safer too.

The SB states the following:
"McFarlane Aviation has addressed this issue by redesigning the part to require locally annealing the work hardened areas. For clarity, a new part number (6818) has been established. P/N 6818 may be easily identified by the presence of a blue or green stripe applied to the side of the spring coil."
To me that means that PN 6818 is required to be locally annealed in the work hardened areas. It also means to me that the new part is not ready to instal until it is annealed.
If that is true we have yet another example of the need to require passing "bone head rhetoric" for any tech weenie to graduate from anything above the 4th grade.
