I charge $30 an hour for my expertise! You spent 3 hours modding that thing with my help, I didn't do it for you to sell it right away.

If you trade or sell it you owe me $90
(seriously I wouldn't do that! but please see where I'm coming from) I am not going to be so quick to help you or anyone else out if it turns into a waste of time for me.

Don't keep it on my behalf either, I don't care what class or RC you run, it simply doesn't effect me. I just don't like wasting my time.
