that looks good, to me it dont matter what it looks like as long as it does the job well, the smoker i modded used a brass propellor from a rc boat, but mine was a modded hl smoker, youres takes it farther scratchbuilding one, the much better option i think, did you think about using a boat propellor instead of a fan? ive found a prop' is much more effcient, and more compact, when you do youre write up i may go youre route of scratchbuilding one and putting one in my Tiger, which has all elmod in it, so hurry up with the write up
