I am surprised it doesn't get mentioned often.
There is an introductory pilot program that is run by the AMA and quite alot of clubs participate.
What this program does is allow someone who is interested in RC to get free instruction on a club owned airplane without spending any money out of pocket. It used to be a 30 day temporary club and AMA membership with as much instruction as you and your instructor can get done (some people even solo during this trial period).
It seems to me that that time period was extended this past year but I am not sure.
Sure couldn't hurt to look into it.
