Sure, email them to me and I'll post them if others are interested in seeing them. I rarely post pictures as well, so every time I do it I've got to go figure it all out again. Sure wish VAF could make posting photos more straightforward like most other websites and message boards...

Sorry. Just assumed you knew how to post pix. Send me your email address and I'll get some off to you today. Then I'll play with the VAF test page myself and see if I can figure it out. It's about time I learned how to do this.

Where do you fly out of? IXD, OJC, Gardner, Miami County? Been to all of them.

Bill, Thank you for taking the time to share your experiences. I have a mere 56 hours on my RV-14a, and all of your input is extremely insightful and fascinating. Even though, I am well past Phase I, it still feels like I am doing a test flight on every flight, and I suppose that will continue until I get to your experience level, with the new airframe.

I'd like to make a better internal cover system for the -14 and have thought about how best to do this. Some airplanes I've seen tied down outside have custom reflective covers that velcro into the windows. How did you do yours? Pictures??

Thanks,
Hope this works as I've been playing with the test pages to see how to post photos. It is cumbersome at best. What you should see are 9 photos showing the three sections of the interior cockpit cover. They fold into about a 12 inch by 12 inch stack an inch thick when stored. No velcro is used; attachment is by button snaps.

The U shaped cutouts on the aft side of the cover for the center part of the plane were originally intended to allow the shoulder harnesses to pass through to the front seats. But after we installed the covers we realized those harnesses should not be exposed to the sun more than necessary so we leave them laying on the baggage compartment floor. Suggest you do the same and not make the cutouts. You will also see how the tow bar comes through as well as how the PVC chocks are stowed in the lightening holes of the seat back supports.

My wife got the material at a Jo Ann's fabric shop but we don't know what it is called. It is much thicker than bed sheets and has sort of a smooth waxy texture to it. We used acrilan for the RV-8A cover but it wasn't available here. Anything white will do. The only drawback is that since it is inside, if you have any leaks in the forward edge of the canopy where it mates to the fuselage, you will have to make up some sort of temporary overnight cover if rain is expected. I still need to test this further but my plan is to use some white electric tape wherever I find any leaks

Looks like you got it figured out, thanks Bill!

Glad you enjoyed it, Greg. To me the airplane itself flies like any other RV and is very docile and predictable. What I mentioned previously is that avionics peculiarities have slowed the learning curve for my situation. The flying parts of Phase I went just fine, especially since this was a typically well tested Van's design that does not make it into the field as a kit until ready. Hopefully the issues you are encountering are minor irritants and not major items like fuel flow interruptions or popped circuit breakers!

Be safe and enjoy the experience. This is my third (and probably last) homebuilt and each one has been a hoot.

Bill, thank you; very helpful. You helped me realize an RV-14 doesn't perform as advertised (e.g., doesn't look like it approaches the published top end speed). The fact that I might, also, find it at least challenging to load the baggage section if the top of the seats are in the way. I was hopeful the RV-14 would meed my needs but I am a realist.

Just a couple of thoughts....

3. I cruise at 155 knots TAS at 2300 RPM and 7.5 GPH. This is good up to about 13,500 MSL. Our -14A will go 180 TAS with FT and 2500 RPM at 8500 density altitude but uses 11.7 GPH.
It appears to me that Bill's RV-14 actually exceeds the published top end speed. 155 kts = 155 x 1.15078 is 178 mph. The published speed at 8000' is 172 mph. Bill's top end speed is 180 kts TAS. The published speed at 8000' is 205 mph. Again, 180 kts = 180 x 1.15078 is 207 mph.

For reference, I've posted the advertised speeds below and are in MPH. Note that Bill is using knots and not mph. The published speeds from Vans site and brochure are below. Note that I've used the "Light weight performance" chart as the speeds are faster than the "Gross Weight Chart" making the top speed of Bill's -14 even more impressive.



Not trying to be difficult, but if you're looking at jumping into a build and a major part of your decision is speed, it would be a shame to eliminate the RV-14 based on kts vs. mph published speeds.

Good luck in your decision.

Gosh I hope you did not misinterpret anything I mentioned in that thread. My comments were intended as an "oh, by the way" update on what I'd seen in my airplane, which I believe won't differ greatly from performance numbers in other similarly equipped -14A airplanes. Yes, baggage loading is a bit of a chore but not a show stopper by any means.

To clarify, I think this an incredible aircraft that does everything it promises. I have never been a speed freak, so if my airplane happens to be 5 knots slower or faster than someone else's, I think nothing of it. For my mission of long distance travel, 155 TAS at 7.5 GPH and 2300 RPM is a good combination of speed, fuel economy, cockpit noise and engine health. Yes, it will do 180 TAS but at an unrealistic fuel burn, at least for me.

The airplane sells itself. In the past 6 months I've had 4 total strangers drop by out here in the hinterlands of western Colorado to see the plane and go for a ride. One is a long time Grumman Tiger owner who is now building his -14 in Wyoming. Another decided by buy an existing RV of some type in order to fly now and will build a -14 later. The third has ordered both the -14 wing and fuselage QB kits and the fourth, just yesterday, decided the -14 is a better fit for him than the -9 or -7 and is starting his building journey.

So please don't make any decision on an airplane based on either advertised top speed or the actual stop speed some owner happens to achieve. Unless you are racing at Reno, speed is only a part of the benefit of owning an airplane.

Default RV 14A flight

I too had uilt an 8A and am now building a 14A. Was there any significant handling/flight characteristics between the 8A and 14A? Thinking about if I might need to get some tranition training in the 14A. Did do training for my 6a and my RV 12 light sport. But flew the 8 after the 6 with o problems.
