Aircraft building, total cost? How can that be?

This is what you last posted.



"Look, I'm in my Junior year of high school. I didn't do so well my first two years, so now i need something to make my collage application stand out like no other.



And what better demonstrates potential, commitment, and ingenuity than a high school student who built a battery powered (green) single passenger aircraft?



My question is - If i get a minimum wage job "flipping some burgers", then by the end of my senior year could I have a completed aircraft? I don't need it to pass any inspections. I don't even need it to fly but all of maybe two reliable times.



It will be powered by a homemade graphene super-capacitor, giving it a superior advantage over other battery powered aircraft (A fraction of the weight, and a highly favorable charging time). Please



keep in mind that this is simply going to be a sturdy well-built frame, with aluminum sheeting where it is necessary (Primarily the wings), one homemade electric motor, two if necessary, and a graphene power supply.



*** P.S**** To make my intentions a tad bit clearer, I won't be flying this contraption more than three feet off the ground. All I want is to be able to say that I built a plane, and that it "flew" (hopped, skipped, bobbed I don't care). Thanks!!!!



Oh oh oh! One last thing.... I'm determined as hell, and have the "know how" to do it all... all but the motor that is. I'm not buying it, this is going to be %100 homemade. I'll do the research but building a motor for this purpose is possible right?"

Now, wait on!



You yesterday posted a question describing an aircraft you WANT to build, and ask how much the cost. Today, you repost and bellyache about the replies you got, why?



According to you today, you and a group have already built an aircraft as described, for $900, AND flown it? Built from junkyard stuff? Oh, come ON now!



I say NONSENSE. The concept you described could not possibly work, so you didn't do any such thing!



Just how stupid do you think everyone, except yourself, is?



You have a problem. You have an unworkable concept, but fail to admit it.

Why be upset? No one was apparently "discouraged" here.





What were the credentials of these people? Why would you take their estimate so seriously? My kid thinks that $1000 can buy a Ferrari, but that doesn't mean that it's an educated guess.

auto part store wnts 200... I found it on ebay for 50. Maybe they have a better part and need to make a buck.

So I tell people that I'm building an electric single passenger ultra light aircraft. I claim that the power source will be a graphene super capacitor ( VERY high energy density, and unbelievably light). I said that I would be hand building EVERYTHING that went into the aircraft, including the three phase motor. I then proceeded to explain that this aircarft only had to fly ONCE.. and that It only needed to get 3 feet off the ground (for safety of course). Soooo basically an aerodynamic box with a propeller.. put simply.



And here comes the good part. I asked them how much It would cost me... 10,000 they said...



Last summer, with the help of a team (my group from school), I built this aircraft.... for somewhere around nine hundred dollars. YES we did cut every corner that could be cut without cutting someone's neck, but it flew.



P.s - The junk yard was my best friend.





MY QUESTION IS - Why did people slap a 10k sticker on my project? Where they maybe thinking how how much it'd cost to build it "their way" (shiny new frame, with a nice carbon fiber exterior)?



I'm quite upset over this, these people are discouraging future engineers from pursing their passion.
