Decided to build a plane using coroplast. Followed the basic dimensions of the FT Duster (Plans available on www.flitetest.com (//http://)) However, modified it quite a bit. So, here goes my first SPAD.
Printed the plans full size and cut out the parts from the coro. This coro is 3mm thickness.
Folded the wing. Made the spar using doubled 5mm coro. The dihedral on the wing is 2 inches.
Again?
No, the same one. Build log was pending
Can you please show how you built a dihedral in the wing? Im new to CORO!
Don't have the photos. I took the two spars (one of each side) and placed them at the angle that I wanted. I then stuck a piece of plywood on either side to hold it in that position. The plywood also gives strength to the centre section. I am starting a new build in which I'll he using the same technique, will show detailed pics of that
Ohkay thank you so much!
You can see it here with photos

Horizontal and vertical stabilizer installed.
Making of the canopy
Making the landing gear
Servos installed...
Sir one doubt,i recently bought 2 sheets of 4mm coro and i want to know how do you cut coro so easily and smoothly because for me its a headache and also hand-ache :P
All remaining electronics installed...
Priyum, it takes some practice. I would suggest practicing on scrap coro and then cutting the actual parts. Also leave enough tolerance, so that if you don't get the proper shape in the first time, you can cut a little more to get the shape.
Everyone has their own favorite way of cutting and bending coro. Go through spadtothebone and spadworld to get an idea. Then try the techniques yourself.
Battery Hatch
Landing Skid
Plane done.......Now for some makeup
All done...
Oh okay thankyou for your reply,and btw an amazing build sir!
Edit - Sorry for bothering you with my constant questions but i have one last question sir,how did you decorate your plane with like those strips and where do you obtain these?
Looks neat, clean and robust.
Seems like you have added too much weight for the wing size. cant say without enough evidence.
Landing gear seems tricky, will try it from my next build.
Where did you get those control horn with bolts. I need them for my Piper.
Thanks in Advance.

@Priyum.
I'm using vinyl sheet, which is available at signboard printers. It's like a huge sticker. I cut it into the desired shape and stick it on the plane.
@v2eagle sir
I'm using the following control horns:

Maiden flight video:
The plane has enough lift, but because CG was much above the wing, the plane wanted to keep rolling to inverted position. We tried about 5 times, 3 of which were hand launch, but the plane refused to fly straight side up. It was too unstable in the roll axis.

Decided to convert it into a high winger, to give it more stability.
Maiden flight after becoming High winger:
http://www.youtube.com/watch?v=qpzveqdowuY#ws (http://www.youtube.com/watch?v=qpzveqdowuY#ws)
Flew a total of 3 flights. On the third flight, I tried taking a sharp turn at full throttle and the plane lost control. Dived straight into the ground. Not much damage, plane is fixable, motor shaft is not bent, however, I did strip the gears on one aileron servo.
As of now, I have decided to not fix this plane and have started building another plane, a 90% AviSpad.
Reverse avispad wing brilliant solution not seen so far done by any one applause
As I read through it flew upside down so design didnot work
