was it a nitromodels F-18?......this is the reason i'm am not going to buy anymore pnp's or rtf ep planes from any vendor regardless the brand. they all have poor qualitly electronics installed in them. a few days ago a guy showed up at our flying site with a foam RTF ep prop trainer plane .after about two minutes into the first flight something crapped out, either the radio, receiver, bec because it went berserk and crashed destroying the model. afterwards we found a aileron servo not centering but we were not sure that happened in the crash. including myself,in the last 3 months this was about the 12th foam pnp,rtf ep plane that crashed at our site due to electronics. they average about 1 to 5 flights before something goes wrong. the only ones that have had any luck are people who bought "parkzone" planes...but they do not made EDF'S.
