I do know that I am a fan of it. Each click is a mini indent and feels good for some strange reason. Maybe with the vibrations from flight it helps keep the mixture where you set it? That combined with the friction adjustment. As
@Ted DuPuis alluded to, you have to figure out the science of half clicking it to get it just OCD right.
And thanks for the kind words
@eman1200 but that was far from a cinematic masterpiece. Felt like it was one of my roughest videos. Lesson learned about having your audio adapter plugged into a 6 year old's headset jack. He managed to unplug it twice fully and once partially. Made for choppy editing and no sound on both landings. Which considering the last landing was my worst in over a decade is probably a good thing because I'm sure I said a few choice words....yes kids present and all. I actually bounced a twin cessna...that takes a special kind of screw up. At least the kids were excited to touch a cloud.
If anyone is curious about what he's talking about, watch the first 2 min of this and you can hear the clicky thingy he's referencing.
