Hi Steve,

I think throttle is a personal preference thing.  I've got most of my time in a Piper which has the quadrant type throttle.  I'm a big fan.  I just switched to a Cessna, and it has the push-pull.  I personally prefer the quadrant type because it's a convenient hand rest.  My arm gets tired holding onto the push-pull throttle, but it's probably just because I'm not yet accustomed to it.

A friend of mine is an aerial photographer, and he flies a Maule (which is, in itself, interesting because it's got two struts in the way instead of just one - but that's another topic).  He has a vernier throttle control in his plane, and he likes it a lot.  I flew a photo mission with him one time, and it made it really easy for him to make minor adjustments to the engine speed and attitude of his airplane with a twist or two to get set up for the next shot.  I thought it was a great idea.  You just have to remember to push the button if you need to make big changes.  Might make a big difference in a higher-stress scenario like a go-around.

All in all, I like the idea of a vernier throttle.  I also like the quadrant.  Quadrant does take up more space, though, and because of its size and the way its mounted, the dash area needs to have the reinforcements in place to support it.  Push-pull, probably not as much -- just a hole and maybe a doubler plate for rigidity.

Best regards,
Chris

I'm in need of a throttle and I'm only a student pilot.
I'm learning in a Cessna with standard pushPull.
Can I ask you experienced guys:

1. What are the pro's con's of: Push Pull Vs Console mounted Quadrant?
2. How about vernier on the throttle if its a console mounted  push pull?
or is this to difficult to operate quickly?

Thanks

Steve Izett
