the Parkzone vapor is a blast to fly, but it isn't indestructible! and repairing it can be very tiring. i have replaced probably every part on my vapor numerous times, but not before i pushed it past its limit; and had a lot of fun doing it! i have flown it inverted, torque rolled, tail slide, inverted touch n go (on the ceiling), torque roll on the ceiling, stall turn, just to name a few. the most common re=pair is the rudder as it is very fragile and i cant remember how many times i caught my self do a tail slide either accidental or to low and watch it fall onto the rudder and *snap* it goes.so lets get to the suggestions! . DON'T land on your roof in more than 1mph winds, don't run out of power while going verticle in less than 5' high, and make sure the battery is secured so it doesn't fly off when you touch the ceiling for fun. now for repairing. to replace the wing u have to cut the wing off closet to the center plastic nub, i don't like to ruin parts but to replace the wing it has to be done! then with a razor blade or hobby knife(something new and sharp) cut the center bums off the verticle carbon then put the new wing on and apply a small amount of REGULAR ca. to repair the wing, i use regular ca very sparingly on the carbon and pull the plastic over it then spray accelerator on it to cure, don't get your hands glued to it because you will have to start over!
