PSK 3500 impeller ??

[jer77]

I got the Octo extreme 200 recently and have been trying to try out the meshwheel mod. I got most of the impeller together correctly but I can't figure out, for the life of me, how to get the original impeller out of its housing in order to put the mesh one in. So can anyone help me out?

Plus how many squares of enkamat per impeller should I use?

Thanks.
