<div class="IPBDescription">But will it fly?</div> I just finished watching junkyard wars, where they had the season premier and had to buold classic planes using classic materials and whatnot.
So, I got curious, and I decided to draw my own in Autocad, and (prepare to be surprise) TOuCH IT UP IN MS PAINT! *gasp* It didn't turn out bad. Remember, this is from a SIDE view. (Although the back landing gear is 3D, to show that it doesn't just have 2 wheels =p).
I'm no genius, so I won't put on the "specs" for it. But I'll tell you what I do know:
Monoplane
Very light (500-800 pounds. Maybe less)
Two Engines. (One in back, one in front, two properllers each)
Tripod landing gear. Not retractable.
Areodynamic.
Extra light Tail wing assembly, using alluminum, (well,t he whole thing is made of it) and wire for reinforcment.
And here's the pic:
So I restate my question: But will it fly?
Fell free to download it and change it to your hearts content. I would like to see if you could make any improvments on it.

they wern`t allowed to use any modern day equipment right ?
well for ur design, hmmm i don`t thnink so. looks to full of stuff, need just the basic sticks to hold it together.
-The wheels need to be level, since the nose would be facing downward if kept the same <!--emo&???--><img src='http://www.unknownworlds.com/forums/html/emoticons/confused.gif' border='0' style='vertical-align:middle' alt='confused.gif'><!--endemo-->
-The front needs to be a smoothe cone, because that divot in the top is going to cause a hellovalot of drag, since it's not flowing over the fueselage, but rather against, and then up, so it's pushing the plane down.
-You'll have trouble with duel propellers, since the front is going to have wind going one direction, and move a certain way, and unless you get it PERFECT, and I mean PERFECT, the back is going to have drouble. In addition, the back one is fairly small, so it almost serves no perpose in retrospect to the front being quite large, plus, if your using double engi9ne, it jsut adds weight.
-Needs to generally be more streamlined, it's almost shaped like a SUV
-The rudders...not quite sure if it makes a difference, but two small ones with a gap inbetween it doesn't seem as efficient as one large one. Sure, if one goes out, you still have the other, but they two would have to be off a main hub somewhere for cohesion, so, they may both go down if one does. Just doesn't seem efficient.
Alright, those are what I got in the 30 seconds I took to galnce it over and let my mind do it's thing. Remember, contructive critism <!--emo&;)--><img src='http://www.unknownworlds.com/forums/html/emoticons/wink.gif' border='0' style='vertical-align:middle' alt='wink.gif'><!--endemo-->
2.) okay, ditch the rear engine and call it a speed indicator thingy =p
And I'll fix the other stuff up =p
imagine every crevase, every area that wind can catch onto.. it will
the most areodynamic thing in this word are cigars...because it slipts air just enough to let it in, and seals the air back up really nice...
with that said:
the angles are too sharp, your going to have a problem with drag once you get it in the air
dual rudder systems are MORE efficiant, because you can have less surface area per rudder to steer, BUT, you have problems with increased drag, and increased manouverabillity (something most pilots aren't comfortable flying with), and also increased risk of possible maintenance...and lastly, increased weight....not a good thing when thinking about an ultralight....
the rear motor is a good thing, but a waste of space, try super-emposing a human onto your plane... can you fit him in? what about his baggage? what about a co-pilot... and their baggage together?
the rear-motors "speed sensor" thing isn't the best idea ever, most planes have this, but are a small intake on the underside of the nose...or even the prop themselves... the air speed created by the prop, lets you know how fast your going.... (there's a complicated math equation, but i don't remember it anymore)
...you won't get it in the air, the way you've got your wings shaped won't catch lift... the air being split likes to stay where it is, and when you've got the air on TOP traveling longer distances (curved up) than the air on the bottom of the wing (flat), it creates lift....your won'gs don't have those two atributes.... it might just be the picture, but you might want to take that into consideration....
thus ends my ripping your idea in two.................no hard feelings....
