RE: Nitro planes
I bought one of the planes they sell that is essentially an unauthorized copy of a high-end plane (didn't know what I was getting into at the time but that's another story). My point is that even though the airframe was a direct copy of a well respected aircraft, the hardware was all crap - control horns that were asymmetrical or the wrong size, metric control rods with non-metric rod ends, missing parts, etc.
They reimbursed me for some replaced hardware, but the money I saved on the plane was not worth the headaches and lots of extra time getting things right. They also use very cheap (crappy) covering that pulls away at the seams when you try to shrink it.
I think Nitromodels is a great place for an experienced builder to get a great deal on an airframe, to use as a pallet for modifications and such. I do not recommend their products for a beginner. It would probably not end up as savings in the long run, especially if you consider the amount of extra time it will take to build the plane.
