"How many kits have you built?" is usually my first question. These kits are for intermediate to advanced builders (like 4-5 kits under the belt...no ARFs)

I have built the Marutaka Bearcat and Zero and have a Skymaster in storage that's about 75% done.

They are all nice kits. Crisp die cutting (almost laser like) however, they are a lot of work. Lots of planking/sanding/filling. If you like to build you'll have no problem. If you only sorta kinda like to build you may get burnt out.

On my Bearcat, it was a true Marataka Japanese kit (It was purchased in Japan). Plans were in Japanese with a little english translation for metric to inch sizes but the pictures were good enough to walk you through the sequence. You had to think about construction a bit.

The Zero and Skymaster are the Royal imports so they were a bit better. I haven't bought any of the new Hobby Barn Marutaka kits so I can't comment on the included plans/instruction.

If you like to build you'll love these models. The build to a very close-to-scale look and they fly very nicely.

My 2 cents
