WELCOME Super Spinach ! What type of flying do you plan on doing?
We are all very happy you found this forum, and you will find a lot of very qualified help here. Yes, I have to admit we're a bunch of strangers who will offer a boatload of advice and try to "steer" you toward certain decisions or conservative thinking. But when you are high enough above the ground to actually get hurt, the help we can offer is pretty important and it will prevent you from getting hurt.
If you tell us what kinds of flying you want to do, and what kinds of materials you might prefer to work with, we can provide some very good, safe, and goodquality advice on how and where to start.
But what you learned from Peter's videos is 100% correct - if he can build something that flies, the so can you.
