Our goal was to crate a flying objeect that wasent a plane or a quadcopter. When we first got our group we didnt really have any idea of what our objest would be. At first we brainstormemed a list of things that we wanted it to be. we cam up with tow prioritys. It would be a blended wing plane that could takeoff and land veticaly. At first we thought that we would have two propellers in side of the fusalage. Then after some thinkning we decided to have the propellers on the out side of the plane. But most of it worked in the end. On Thusday after camp ended I stayed and fixed the plane because it ahd crashed earlier that day. One of the hinge servos was not working so verticol take of was out of the question. It was going to be a tose launch. It was tosed into the air diped down and then shot up and to the left trund and crashed spliting in two. I did not care that it was brockenl, it had flone and that what we had been trying to do.

It took a week and a half of hard work to build and fix the aircraft. It consisted of two large wings with a laser cut tail in between the wings. The motors and propellers were mounted on pilones that stuck out of the front of the wing. On the tip of the pilones were hinges that moved the propellers from vertical take off to horizontal flight position. The hinge piece, which was 3D printed, was the most fragle part of the entier aircraft but we spant alot of the time working on it.

I think that is we had more time there would noit be much that we would change I think that we should make the wings smaller and more forward swept to move the center of gravity up and lessen weight to allow for a better chance a vertical take off.  I think that we also couild design and make a way to luanch the plane and get it going faster. we might also need to add elevaters so that the plane would be able to control pitch better. We can make the wood arm stronger to reduce the damage it made when it was vibrating, and it can keep on flying longer instead of breaking up. we might also make the hinge strronger so if it crashes it will be able to suvive. 

Our plane contains one propeller in both two  wings. There are two wood arms that we use to hold the propeller and connect the propeller and our plane. Besides, the propeller can rotate 45 degrees. In our test, the rotating part works successfully. Our plane has two elevators and one rudder to control the plane. However, the shape of our plane is not perfect. The center of gravity ls not in a proper place so that our propeller cannot make the plane take off vertically. The force which supports the head of the airplane make the plane unbalanced. In the first flight test, we trieed to make the plane take off vertically, but the plane was not able to fly. In the second flight test, we solid the wood arm to make sure it wouldn't vibrate and change our way of taking of. This time we tried to make it take of in regular way so we throw it . However, it had kept fly for about 3 second and then fall. I guess it was due to the super huge wings that our plane use and the position of the battery. The head of the plane became too heavy to fly.  

But most of it worked in the end. On Thusday after camp ended I stayed and fixed the plane because it ahd crashed earlier that day.
