I'll let you in on a little secret, Menthol, but you have to promise not to tell anybody. RC Universe has a huge User Review section with reviews and comments about virtually every make and model of kit, ARF, RTF airplane, radio system, and engine on the market. You can view the World Models Sky Raider Mach I reviews here:

While there aren't any full-length reviews here at RC Universe, there are a lot of user ratings and they're virtually all very positive. Reading the detailed comments will give you a good idea of the experiences various owners have had with the plane. Compare them to ratings and comments left for the other trainers you're considering.

Be careful to guard this secret section as best you can. If word gets out about this feature, then everyone will be leaving feedback about various products and more and more people will go comparison shopping.
