Default Quadrant designed in?

This question is primarily for rvbuilder2002, but anyone with info is welcome to answer with what they know.


On the RV10, the plans had a section for both push-pull and quadrant style controls.

When I took my demo flight at OSH, the guy I rode with said he didn't think Van's was planning a quadrant for the RV14.

There's no way that I'll be building mine WITHOUT a quadrant, so it would be nice to get a heads up on if there will or will not be a quadrant option in the plans, and in the finishing kit. If not, I'll try to leave any potentially interfering things out and start figuring out how to modify everything to accommodate.

BTW: The one for the RV10 works exceptionally well, and I love it. Most formation groups insist on no vernier types and quadrants are preferred for formation flying.

I will most likely have a quadrant in my -14A as well. It would be nice if the factory could/would develop this option for us. If such an factory option existed, I am sure most would opt for it.

Hi Tim,
At this point in time, no development work has been done to accommodate a quadrant and I am not aware of any plans to do so.
Because the seating position in the 14 is quite a bit different from the 10 (in the 10 you are sitting higher off the floor... in the 14 your legs are extending more out in front of you), and the fact that the 10 has a wider cockpit, the use of a quadrant would directly compete with the design philosophy maximizing fit/comfort for larger people.
I think a quadrant would be fighting for the same space as some occupants inboard knees.
Not saying it can't be done, but before you go to all the effort I suggest you make a mock-up copy of the one in your RV-10 and see how it works as your fwd fuselage comes together (pay particular attention to where your knees have to be to get full stick deflection left and right).
If there was enough interest, it might be looked at. I suggest builders who are interested should send an email to support@vansaircraft.com. Put "attention engineering / RV-14 throttle quadrant interest" (or something similar) in the subject line, and make your interest known.

Same concept to what is in later model Piper Cherokees such as THIS

I sent Van's an e-mail as Scott suggested yesterday and received the following from Gus today.

Ron,

There's no list? But one of our design goals for the 14 is a throttle
quadrant option similar to the RV-10 - so that should be available
with the firewall forward kits when they are developed.

Well there you go, I wasn't aware that was planned for the future.

That is awesome because I sure like that one in the photo for a constant speed setup. Someday.

Default Quadrant Installed

For those interested, I found that the RV-10 quadrant has the same panel to subpanel distance as the RV-14, or at least close enough that it was an easy install. So I've obtained and installed the RV-10 throttle quadrant on the panel.

Past comments about the seating position being different and it perhaps not working well in the RV-14 are off base. It appears it'll be a very comfortable way to go, and it is in a great position. Of course, while I have my IO-390 waiting to be installed once the engine mount arrives, I don't have cable lengths at this time, so I'll need to get that later. I don't see that it's going to be any problem to use though. I've got some of the green lower-temp cables that I pulled out of my RV-10 that I can use for routing and measurements, and then I'll order some of the nice black higher-temp cables for the -14.
