for now I would just recomend that ya tell them that your just learning yourself and that you expect that you can't yet show them how to fly it.
Personaly, I just bring my cx2 along when I fly , and if any one wants to give it a try I show them how to fly that. most crashes with the cx2 cost about $3 and I can afford that with the hopes of getting others interested in the hobby. if any thing I have the experiance of having people want to fly but being too afraid of breaking things to try it. the cx2 isn't a toy but its almost as cheap as a toy to fix. I haven't yet had any one ask to fly my cp pro , I expect its cause they see the look of concentration that I have when I try to fly it. that and with trying to learn 3d over 1/4 of my flights end in a crash.
I thought I was fairly good , untill I tried to start flying upside down.
