What have you done.
Well, first, if you look at my post count you can see that people on this forum know me, whether they like me or not.
Second, I've been building, designing, and flying all sorts of models since I don't know when. If you count putting two "skeeter" models together into a twin as "airplane design", then since I was 8 or 10.
Third, I've been involved in business long enough to know that when someone unknown bursts onto the scene and says such things about someone else, then
someone is in the wrong. However, without further proof you can't know who. I've seen it swing every possible way, from baseless slander to accurate reporting of fraud, with some rather astonishing variations in between. Since Dane vouches for you, I'm more ready to believe that your statement is legit.
Fourth, I started flying serious CLPA in 2010, crashing at every contest I entered, and was flying Expert by 2015. I had to take 2016 off with joint problems, but I'm back and managing to put in credible flights for bottom-of-the-pack expert.
