RE: Evolution 60 NX in a 40 size case...
This .60 NX sounds like a great engine. It size and weight made me wonder how it compares with my K&B .61 Twister. My Twist weighs 14 ounces without muffler. For some people it might be a good alternative especially since it's a good bit cheaper down to $79.99 with a trade in.
Best regards, Bill
