Funny you should mention pr....I called Jeff at medusa today to ask when the 70 and 80mm would be ready and he told me sometime in September....I told him that I would keep my 36-60-2000 then and just move it to another truck when the 70 is available.....he then asked would I give him some feedback on how the 36-60 performs and i told him there's a guy in the forums named asheck and his erevo with the 36-60 does a standing still back flip on to its wheels....he was so excited and amazed that he wanted to see this feat of torque envy...I'm going to link the video to him
