Ihave built (put togather) 22 airplanes this past year. 2 of them being stick kits and the others ARF'S. All I can say is I have had a blast and it is my first year in the hobby. I am now putting to gather ARF'S for other guys in my flying club here in NC for a little extra cash. I also get to madden and trim the planes that I build (put to gather). I have it down to about 4-6 hours for assembly and electronics installed. I have assembled planes from 40 size to 50CC gassers. Did I mentioin I have had a blast this past year. I soloed after 2 weeks on the trainer and a year later I can make my Super Stearman 3D. I have had a blast this past year and cant wait to try new stuff this year. I had no idea that having all this fun was legal.
