Okay, so I just got the Igo-M, which is something I had been wanting to try for quite some time because of the massive stock airholes. I was so excited to start building on it, and right away I noticed a pretty big problem: the center post spins like nothing else. There is no resistance to it AT ALL, I can grab it with my fingers and it will twist out of place like there was nothing. I've seen quite a few reviews on it and haven't ever seen anything about a spinning center post on it. Does anyone know of any fixes for this? I bought it for $45 and if I can't build on it then I'm out that money which is a real bummer because I really wanted to like it.
