RE: Mind that throttle!
Some I do. A lot of the base pictures I got from Minnflyer. When he moved up to a Community Moderator position he knew that he wasn't going to have as much time in the forums, so he let me download his base stock of RC diagrams and pictures. A lot of times I will use those as a base for a diagram that I'm working on. I aslo keep an eye out when I'm out on the web. If I see a picture that I may be able use later I will download it and hang on to it for later.
