I must admit, his style is sometimes a little grating, but, overall, he does the most engaging videos in the RC world, so, props to him. As for him selling his ebay tips, I see nothing wrong with this if it's honest. I can see what others have said about this though, as there are a lot of people selling similar products that are effectively scams. Again, I have not bought his stuff so cannot comment, I am sure it's fine. I tend to skip the part in his vids where he talks about it and get to the bashing.
Cheers @Kevin Talbot for the entertaining content.
