    Hey all,
    A friend had spurred my interest in the hobby world of building experimentals and now, i wanna get into it!!

    I have been building drag racing division winning Type 1 VWs (bugs) for almost 18yrs, and really wanna try my hand at building something other than cars....but, still be able to apply some of that knowledge.

    I am a swiss-style lathe machinist/programmer by trade, so, i got the technical and critical thinking, just dont have the experience yet!! :)

    I have been thinking for the sonex or waiex kit, simply for the compact storage aspect. That really appeals to me, whatchya all think?? Not to mention, with some tweaking, vw engines are second nature to me. Highest hp one to date has been 235hp @ the tire N/A motor (dyno tuned)
    And 748hp with 38lbs of boost (dyno as well). I do understand airplane engines are different because of altitude changes so much, but, an air pump is an air pump!! Lol

    Anways,
    Looking forward to getting to know some of you guys and, hopefully, you all wont get to upset at me for asking newbie questions! Haha. :)

    I was going to suggest you might want a design with VW power.......

    Hi; hope you love your new hobby. In regards to making more HP it takes roughly 4 times the HP to go twice as fast, most of additional HP goes to rate of climb performance (generally). Boost will maintain HP to an altitude that you stop porting pressure but the propeller will lose efficiency and the wings will lose lift but also will have less drag, so you will go faster at altitude with same HP because less drag. Airframes are speed limited, things like control surface "flutter" enter into the picture as you go faster. So a particular airframe may only realize a benefit in increased HP as regards speed up to its speed limit and additionally may not have fuel capacity to support the increase of power for any reality of endurance. I.E. change one thing change everything. Good Luck.

    Welcome!

    It sounds like a VW powered plane would be a natural for you. But be aware, aircraft engines are different not because of the altitude changes (though that can be an issue if you regularly fly at high altitudes), but because of the high continuous power settings. 70-80% power is a typical cruise setting. Most VW aircraft conversions are no more than 60-65HP. Aerovee does advertise an 85HP normally aspirated and a 100HP (many question that number) turbo version... they cay 40" MAP for 2 minutes, 35" continuous, though they don't say what the continuous HP is. The big issue is heat rejection, not such a big deal in a dragster but important in a plane where the cooling comes from ram air (no fan), and cooling drag is something you always want to minimize.

    Welcome to the forum, and aviation.

    I would start your adventure at an airport getting a ride in a Sonex etc. Then take time to look at other airplanes like biplanes, Sonerai (folding wings) ultralights, Hummel bird , all sorts of options. Study, learn and get your feet wet before committing to a certain design this early in your path.

    Again, welcome aboard

    That was actually my original thought, i havent gotten a ride specificaly yet in a sonex, but, i have done alot of research and been to a few air shows and checked out planes... some of the owners did let me sit in their plans...which i thought was pretty awesome, but, im also a small guy, so, sitting in the sonex did feel pretty comfy.

    As far as the heat dissapation, this im very familar with, again, a new animal for aviation, but, i have also do road racing with the bug....where rpm was 3500-4000 nearly the entire time, again, not saying they are the same....but, i do have some tricks to help with that problem. But, that note of knowledge is definitely written down.. :)

    I wouldn't be overly concerned about heat. Sonex are well proven and lots of people follow a successful order to these kit built airplanes. Follow the plans and advice and you'll have a nice airplane.

    Aaron is so happy with his Sonex he even sings for you.

    Right, they're not. In a car, rpm is not necessarily related to the power output but the speed and gear ratio; you can be coasting with your foot off the gas or running in a low gear with a low throttle setting but still at a high rpm. In an airplane, under most conditions, power is proportional to the cube of the rpm (that's the way propellers work), so, for example, an engine rated for full power at 3400 rpm will be making 80% power at 3156 rpm.

    However, I'd still take a Sonerai over a Sonex any day of the week.

    With him stating he is small. I would look into a Cygnet.

    Those are some pretty cool videos!! I do really like a couple of those planes....but, for some reason the sonex really appeals to me.
    The aaron videos are great!!! Exactly what i can envision me doing.. hahaha

    You need to find your local eaa chapter. Also they make maps of where to find fellow pilots. Skyvector.com 20170211_082754.jpg

    This is a cool little airplane and has a very good cruise speed.
