There is a few people on this site that says they have done it.
I personally do not know any one that has done it with success.
But i have had a few that tried with no success and has sense
been trained by me and now are avid flyiers. We have 2 big
clubs near us and we train for those clubs at times when they
have a lot of people to be trained. Our club is very small and
way out in the boonies. 70 % of the people we train doesnt
join our club. They like the newer and bigger clubs. We do our
part for the R/C community ever chances we get.

If you try it own you own than good luck.
