Hi, I bought Kyosho Calmato and I've got it only for one week. I'm real beginner - no experiences with RC planes and I was so surprised how easy is to build this ARF one. I ordered model with GX.40, this is the best value for Kyosho's one as model is only 2500g weight. All i needed to build model was glue. All other tools I had and I think everybody won't neeed more. You need only screw driver, knife and pincers.
