Just curious: Why split flaps? Do you plan to use them as brakes to get down faster for the next tow? If so, that makes good sense.
Actaully, yes- sort of. I know split flaps are not what you want to use for adding lift, but drag. I have designed this plane not to need flaps for takoff and landing because of the afore mentioned wing loading, but I was thinking that it would be interesting to see what the added drag did to the decent angles. When I started the design, I was drawing with the following factors in mind: 1) I wanted a slow flying plane, sort of like a old timer. I was picturing one I saw at a field I used to fly at- the guy was an engineer for Lockheed, and had built an electric powered plane so slow he could fly it backward in a light breeze. This was back when electric planes were a rarity, and NiCds was top of the line

2) I was looking really hard at the Sig Kadet, but it really didn't do justice for the old timer flair I was thinking about. Nothing on the market really tickled my fancy, so why not roll it myself? 3) Big planes are cool, so why not make it BIG. I had an extra .91 four stroke that needed a home, so let's see how big we can get for that power. No- wait- just for grins and giggles, how
big could I get if I dropped a 1.60 in it? Na that's
too big, right? Why? My hero, Howard Hughes, never thought the H-4 was
too big, did he? Well, the cool factor just increased exponentially. 4) Make it simple. The best answer is usually the simplest. Ie: profile fuselage, airfoil that can be built flat on a building board. 5) Cut cost as much as possible, let's use some foam in this thing! 6) Cool factor can't hurt. Bush planes are cool, it's GOT to have flaps.
Using it as a glider tow was an after thought. My dad has always wanted to build a glider, but we don't have any good slopes, so towing it is probably the best bet.
Thanks for all the good ideas guys.
