Kyosho Caliber M50

This is a very rare kit. It was one of most expensive 50 class helicopter of end of '90. It is the Kyosho Caliber M50.

It is the little brother of Caliber 60 the max in rc helicopter technology in the begin of 2000. It has the same aluminium chassis and it is a masterpiece of engineering. It is all in metal, head included.

I already own a restored Caliber M50 but this is a New In Box Kit so pretty impossible to find.

Here my RTF Caliber M50 reviewed in my blog. I upgraded it with original carbon frame set.
