Well a trainer kit not only trains you to fly, but also how to build. There are alot of techniques and tips that go into building an airplane. You can use the trainer to teach you these things. Even if you destroy the trainer, the knowledge will still be in your head. No crash can take that away. You can use that knowledge to rebuild the trainer, build a new one, or whatever you want.

I am putting some time into my trainer, LT-40. A good trainer is so stable in flight, that any competent instructor will be able to fly it with relatvie ease. You can keep flying with an instructor until you are sufficinetly confident in your ability to fly.

Why buy a nice car, when you can crash it on any given day? There are so many old ladies, maniacs, testosterone filled teenagers, and ditzy girls on the road, the chances of denting your four-wheeled friend is relatively high.

Anyway, thats my view. Its the hobby that really matters. Anyone who gets into this hobby knows they are going to lose some airplanes. As one poster said (Forgive me for not quoting the source ): "It's nothing a six pack won't cure"!

Good luck.
