i think "drone" is trending these days, not helicopter, the drones have REALLY changed the game and are putting MASSIVE amounts of money into advertising, sell it asap, IMO
i do but believe the hobbist who has an rc helicopter has potential, but not sure if they are switching to drones?
having said that you could consider that there are STILLLLLLL people shooting on 35mm film and developing their own photos the old way + even after the invention of photography we still have painters ! ( my art history training coming in here now ) , BUT......... in each case there has always been a substantial number of years before the retro REBOOT happens, @ 20yrs for painting at the turn of 1900 and around 20 yrs at the digital from 1995, but maybe just 10yrs before kodak went broke, agfa went broke and fuji went fully digital !
IMO "rc" isn't coming back big time, just look at the drone ads on youtube !, they are amazingggggg.
soon we will have a personal drone followinf us and feeding our every move to a server so if we get attacked it will all be recorded " hand me your wallet" ....reply " ummmmmmm, look up mate, my drone has already phoned the police, so F off "
