Want to finally get into building RC planes, do you think my plan is good?

#1
Hello guys,
I am Jan from Germany, I'm 15 years old and I've been interested in RC for a long time, I think I started watching FliteTest when I was 11 or 12. Since then I've always wanted to build my own RC plane or racing drone, but I just kinda pushed the idea back because of the high cost and the fact that I already had a couple of Hubsan X4s and a Yuneec Q500. Now I'm thinking of finally making my own plane, but staying at a very low budget of <150€.

I already have a nice charger, so the only things I'd really need would be a radio, receiver, motor, esc, batteries and a couple of servos. I am thinking of going for a FrSky QX7, which would leave me with a budget of 50€ for the rest of the electronics, which should be fine if I get them really cheap at banggood. I do not excpect them to last, and I am probably going to crash them anyways so the low quality shouldn't be a problem.

Now comes the part I am a bit doubtfull about: I want to make my plane from just Depron and without any real plans. I have never been particularly good at following plans exactly, lol. I think I can do this since I know basic principles of aviation, e.g. CG placement, control surface sizing, e.t.c. I have tried building planes with wingspans of >0.5m from just newspapers, which worked suprisingly well, so this gives me some confidence. I would make my plane up of a wing constructed with Andrew Newtons method, and a simple box section fuselage with plywood firewall. Do you guys think I could achieve such a thing?

Thanks in advance,
Jan

The QX7 is a fantastic radio, but keep in mind the receiver is $20 - $30 (here in the US). That leaves you with $20-$30 for guts, and that'll be really tight. Do you have an income where you can save up a little bit longer?

Thanks for the replies! I will order parts from banggood so shipping might take a while, but I'll post an update when I built the plane.
@Chuppster
I found a receiver on banggood for 15€, that should leave me with enough money. I could also spend more, but I dont want to really. My budget is also 150€, which amounts to about 170$.

You need to be careful ordering from Banggood in Germany.
If the vendor didn't do the paperwork for you customs will make you pay VAT on top as soon as your total invoice is more than 22€ and they might not even hand over the goods if they're not marked with "CE" conformity.
You will also have to pick up your packet at the customs office, which might prove an additional challenge for a 15-year-old. These things aare few and far between and their opening hours are... typical government agency.
