I made I typo talking about the GK version. I put GN. The GK stands for Golden Knight. I don't know if a GK was ever made in the 82. On the 72 they made both and for some reason the GK had the stack. The GK cost $20-$30 more but I assumed this was for the powder coating. Maybe part of the money was for the stack? I'll put pic in the next reply.
I am a huge fan of the Scimitar props on the 1.25. I have not tried one on anything else. Once I find a good prop I stick with it. I am running a Zinger Pro Series 15x4 on my .82. When i break my spare I will have to try a Scimitar.
