let me tell you my story. i got all A's on a reprot card, so my dad got me the park zone j-3 cub. there were some problems with it, so i sent it back, and after about 1 week, i reseaved a new one in the mail. for free. then i took it to my hobby store, and reterned it for the aerobird challenger. when i took it out of the box, the tail boom, and electrics were out of place, so guess what! i sent that one back, and got a new one in the mail. i took it out to fly for the first time 2 weeks ago, and it is amazing! I love it, and it is defanitely worht the wait. keep tring!
