Nitro Models?? Junk hardware, missing parts, chinglish instructions. The planes themselves, about par for the course with all the other lower end ARFs, not bad for the price and if you don't do anything in the way of pilot error the air frames are good for a year or so. Depends on the pilot and how you will fly it. I never see very many old low end ARFs at the field, maybe the hot glue they use comes apart or something?? You get what you pay for!! Sometimes!!
