/diy/ - Do It Yourself

not sure if I should even speak up after anon raged about casuals and mouth breathers, my approach is half-assing and learning on mistakes, but here it goes. please don't get too annoyed, figuring things through trial and error from scratch is kind of a weird hobby of mine

So, I'm trying to make a plane for some time already, previous attempts were a bit more lame, but in this one I actually got to control it for a while. Looking at webum, do you think this is 100% my mistake as operator (most likely, quite literally never got to fly any real rc plane in my life before this one), or is it possible I've got affected by wind, and I should add some dihedral angle between wings? I was surprised how sudden the spin was, not entirely sure what caused it.
