Smiley build log: my first home built micro

I would say its a scratch built, but i'm using the plans from derJuF posted in this thread ( called "Smiley".

I'm planning on putting the AA components on it, with the motors setup as pullers vs their default pusher setup.

This is my very first home built RC plane so we'll see what happens. Here are the pictures of my progress so far:

Yup, I just got some 2mm Depron yesterday. Though I think next time I'm gona get 3mm instead. I'm not sure how sturdy the 2mm will be.

By the cutters are so much fun! LOL

Anyone have tips on how to cut good curves with a hot cutter?

That'll be a neat little plane. I thought about building it too. I ended up building one I created from a couple of plans I saw. I joined them together. I am waiting to test this weekend. I hope it flies. Your doing a great job. Good luck, Steve

Almost done...This has been a lot of fun

One question. My little Smiley has a case of the droopy wings. Both wings hand down instead of straight out or a little up. What can i do to fix this?

You could build a little more structure in the fuse to hold the wings at the correct angle, or run flying wires (thread) from the top of the fuse to the wings to hold them up. Or let the wings droop when the plane is stationary and see if they actually bend upwards when the plane is flying since they are supporting the weight of the plane at that point.

You could put a former in the fuselage in the shape of a shallow 'V" above the centre of the wing. this would push the wings down where they meet in the centre. this will give the wings dihedral, (tips of the wings higher than the root) which is essential if you want the plane to be stable and to turn properly.

By the way nice plane.

britchris...I think thats what i'm going to do too, drop the two piece wing design and cut myself a single wing, score it and put a brace on it to hold the dihedral.

I dont like the two piece wing thingy. The only reason that the two piece wing makes sense is that it'll be easier for you to put the reciever and battery in. With the one piece wing it'll be harder. I'm thinking about making a cut in the bottom of the fusalage and inserting the reciever and battery there, with the reciever user interface flush with the bottom of the fusalage.

Another thing i did was put brace in the bottom of the wings about 1 inch outside the fusalage to hold the wing curve.

derJuf: Your not a star, your a super star! This is a cool little plane

I have a question though. These plans are a bit different then the ones you posted on the AA mod part 3 thread (page 7) that I followed. In the plan you just posted, the fusalage bottom width is almost twice as wide as thes the original plan called for (the long rectangle with the triangle at one end). Did you find that a wider body gave better flight performance? Or is it just a cosmetic change?

britchris: One piece that isnt on this plan derJuF posted is the piece that joins the two fusalage halfs together on the TOP of the plane. The top piece is similar to the long rectangle with the triange at one end, except the rectangle is shorter.
