the fun 51 is cheap , but not much good at 3d it won't flat spin very well and you can't compare it to an extra special dosent fly the same , i know they are about the same plane but it just doesnt fly as well, if your looking for a cheap 3d plane buy yourself a an omp edge 540. now that is a great CHEAP little plane the kit is only 60.00 and yes you get no hardware with it but it does have landing gear and the servo's are in the tail so all you need is some 256 hardware that you could steal off your old trainer. . i have had a few extra specials and yes they are fun but they are a thing of the past get up to date and buy an omp. might as well start with something that is worth your while instead of old junk.
just my .02 cents worth
