$79.00 is a deal? $199 for a 70mm fan and motor?
you can get the equivlent motor to the mightty might for way less than 79 and a Wemo minifan and a Nue motor to fit it would be less and a lot better than the Hoffman Beast.
You might want to check out
this thread before buying one too. Hoffman is out of the RC business.
Since your a vendor you really should have it listed on your signature.
