I saw that OS had a four stroke out for helis do not rember seing that when I got my os50 2 stroke. The question I have is my second heli is a gohbee 30 that the engine may need to be replaced it is starting to sound like a hammer. If I replace it I will probably upgrade to a 50. does any one have any thoughts on the four stroke. I like the four stroke on my plane but have not been able to find out much info on the four strokes for helis.

There's a reason you don't hear about it much, with very few experemental exceptions, nobody does it and it wont fly a Raptor 50 anywhere near how a 2 stroke will. Also very few of the helicopters are geared for it.
If your engine is making noise, replace the bearings.
