Here is a question I never thought I'd find it necessary to ask. I always assumed I was going to put in a quadrant engine control set in the RV-10. I was used to using the quadrant with my old Warrior, and never having flown a vernier-controlled airplane, just assumed I liked it best.
However, since I bought my Mooney 201, I have been very pleased with the fine control available with the verniers on propeller and mixture. My 201 has a non-vernier push-pull throttle with a concentric ring friction lock.
I'm not sure I'd be able to lean with the same precision with a quadrant mixture control that I'm able to with the vernier. Also, the vernier seems to offer better stability against drift due to vibrations, cable tension, etc. I never did any precision leaning with the Warrior, since it didn't have adequate engine instrumentation and was carbureted. I experienced some minor control drift with it, as the friction lock was well worn.
I really think I still prefer the quadrant for the throttle control (I plan on flying the RV like I fly the Mooney--wide open throttle pretty much all the time), but may consider vernier controls for the mixture, and possibly the prop. I could do this by using a two-lever quadrant control for throttle and prop, and installing a push-pull vernier in the panel for mixure.
I can think of some pros and cons to this approach:
Pros:
Finer control of the mixture and possibly engine speed.
Better resistance to control position drift in flight
?
Cons:
Not all engine controls consistent with each other
Not all engine controls in one place
Not standard to any other aircraft
Effect on resale value (hopefully not an issue for a long time, but still...)
What say you?
