If you use the slider canopy and use the "tip up" modification that "aircraftextras.com" has for sale, you can use the baggage area with ease. I saw it at Oshkosh and watched the designer open and close the canopy with ease. The access to the baggage area to me is important as my wife and I will be using out "9" for cross countrys. The original slider makes for a tight loading arrangement and the tip up canopy the same. Just a thought and a consideration.

Perhaps using a saftey strap to keep it from flying up! Vic Subject: Re: RV9-List: Canopy: Tip-up vs Slider/Synergy Air --> RV9-List message posted by: Richard Scott Bob, I did the Synergy Air course last year and it was very good. You will learn a lot. Plan for a very loooong day if you commute, starting the class at 8 & ending around 6. Closer to home there is the Henry Gorgas course, which is a 2 day thing & it is over on the west side somewhere. Henry gets good reviews, also. Slider vs. tip up: On the RV List the consensus seems to be the work involved is about equal in terms of time and difficulty. The big advantages of the tip up as I recall is instrument access and unobstructed visibility, while the slider has the cool factor. I believe the slider is safer if the plane goes on it's back because of the location of the roll bar--draw a straight line from the nose to the tip of the tail and look at where the roll bar is in relation to your head & you'll see what I mean. On the other hand, Mike Robertson of the FAA says there is no difference. Regarding instrument access, the tip up advantage can be negated a little by using a modular panel in the slider. And at Van's homecoming a couple years ago, I saw a tip up left open and there seemed to be a lot of stress on the thing when a breeze came up. No problem, of course, with the slider.

Several airplanes owners are changing the carbs and/or fuel injection system to burn alcohol RS$1,6/liter <==> US$2.13/gal. There isnt alcohol in airports gas stations, only out of airport gas stations. The problem is some airport management dont agree to bring alcohol from a gas station in some bulks and fill up the tanks. It could be done in airclubs without problem. Lycos engines could burn 87 octanes fuel. We call it "avcar". Avcar costs R$2,00/liter <==> US$2.67/gal. The problem of bringing fuel from out of airport gas station is the same.

Extra weight and complexity means lower useful load and longer build time. :( I selected the tip-up because of the unobstructed view it offers. Still, I think the slider wins major "cool" points.

I believe the Germans tried that in WWII but I'm not sure how successful it was. As I understand it, alcohol absorbs water, thus it isn't considered a good option for aircraft use. In the US, aircraft with auto fuel STC's can't run auto fuel with alcohol (Gasahol is what we call it up here.) because of the water absorption issue. I would think installing a diesel or auto engine conversion would be a better option for you.

I think it would look something like a Spartan Exec and sound just as good as the Exec looks.

They dont need to drain the tanks :-)). Some papers show the maximum water absorption is 3% of the total volume. No problem burnning it. The major problem in using alcohol is the consuption. It is bigger than avgas consuption. If the compression of the engine is raised by machinning the cilinders the maximum power output will be raised too.

I am very disappointed in this product and do not recommend it. Years ago I used a wash primer similar to the SW on my RV-4 with very little problems, however the SW was a real nightmare. My main issue is spitting of chunks of semi congealed primer on the surface and runs. I mixed the primer per the directions, tried different pressures and different guns, but still similar results. I live in Arizona and the climate is a bit dry which may have contributed. The inside of my wing skins are speckled with primer, but know one will see this. Now that I am finished primering all my wing components I will be using the AKZO primer on the fuselage. It may be more of a little hassle to set up, but the results appear so much more consistent then the SW primer.

I always leave it unlocked and partially open on the ground. On the ground it gets very warm if left closed but you can release the latch and lift it up and prop it open with the lifting handle rotated to hold it up. Works out fine. It doesn't need to be held down. I'm told that if you forget to latch it before take off it just lifts up a bit and cannot be closed or opened further before you land and close it. Dennis Thomas
