I have been building airplanes for 15 years now, realliy like yout proyect… but:
why do you make the wings that way, they are not strong for a fly, they need reinforcements, where are thre servo pictures? i cant see the controll horns…
does it ballance? where does the batteries go? the tail controll surfaces seems to be little…
How are you going to controll it?
you need more support in the body of the airplane in the part that holds the wing…
how did you make the wing profile… i can help to design a better one… look for the NACA 4415 profile for a start
Personally I wouldn’t be to optimistic of getting this plane in the air. But for all i know you might have years of experience with RC planes? If not i would have started with a proven concept RC plane and worked from there.
I think you have a lot of repair and gluing in front of you
As mentioned by avent you need to rebuild the wings, these will just break when you will pull up/down to fast. Having a completly flat bottom wing is neither recomendable. It will work and produce lot’s of lift but it won’t make the plane better/easier to fly.
Where you connect the wing you want some plywoood NOT balsa. It's being used because its very light not for structural strenght.
For a UAV I would also use dehydral on the wings so it will self correct during flight (rolls) and I would put the control surfaces in the wing, not in the tail. This thing will take a week to turn arround and it will always either dive or pull up when trying to make a turn. It won’t work I’m affraid.
I will be very, very surprised if you make this thing fly. And if you do so, I will personally come down with a cold beer if you make it land in one piece
But hey, it’s all about having fun and learning! Go for it!
I don’t really care about dihedral nor about having a high wing since the autopilot on board will do all the corrections ;) as for the control surfaces, they have not yet been cut on the wings im waiting for the servos and horns to arrive so i can set them up and cut them properly
sure it isn’t an ideal design, but a good autopilot should be able to make it fly, remember the F117 would fall out of the air without computer control.
and if it blows up mid air, make sure to post a video.
The plane has a weight of 800 grams with the motors but without any on-board electronics each motor can pull 750grams, odds are, its going to fly besides, its being designed with the help of the local RC club they are confident that it will fly
I don’t want to be a downer, but it seems also ways to heavy with 850g. I would also change the color that you find at least the wreckage after a crash landing Here is an interesting paper in how to design gliders, boost gliders, but this also applies for your attempt. Maybe useful.
