The kit is poorly processed. The imprints of the wood is not complete and the parts do not fit. The holes for the chassis sit at the wrong place. Since the kit consists of balsa wood he breaks easily when contaminated, making the parts despite inaccuracies docile. The instruction is poor. I think, for example, Lego makes it before how to write a useful manual. The solar cell or the engine is broken in my kit.
Who wants this model to assemble should have a high tolerance for frustration and a lot of glue. The price of this model does not fit in my opinion.
