I was looking for something exactly like this a few months ago, when I was still flying (taking a break currently). I think it's fair to charge $4.99 for something like this.
And with Jet A prices where they are...
100LL for me :)
You mean, one 5* review.
Why isn't he charging for it? I'm not sure if that should make me less ("he can't figure out pricing") or more impressed ("he doesn't care about just money").
