OS61SX-H WC

I'd want restore one of my vintage GP helicopter. It's a Hirobo Eagle of 1990 in a Jet Stream Kalt body. So i just bought froma friend this new (from old stock) heli engine from Japanease O.S.

It was the best engine, of begin of 90', in Class 60 (10cc). The 60 was the standard class for F3C competition at time (to 2000) and you can use it with 30% of nitro.

I will update my blog when i will restore the Eagle.

Here are some pics about this old awesome engine.
