I have both kits and arf's. The best reason to build the kit when you are starting, is that if you know how it went together, it will be easier to repair, and you will have to repair it! Not trying to scare you, but crashing is part of learning. (have crashed my trainer 4 times so far) still learning. (trainers are supposed to look like patchwork quilts, right?) LOL Good luck Loren
