Such a cool little model! You can tell it was well crafted with precision milling, very well constructed.
Shipping was surprisingly fast (2 weeks).
Spins fast, but not too fast to blow out its own flame (although if I increase the wick's length, the flame would be bigger and hence would spin faster...but need to be careful as the red and green gaskets/washers are plastic and could possibly melt if temps got too high). I only have about 2mm of wick exposed.
I used over the counter 90% rubbing alcohol as a fuel, which burns very clean.
Fun little motor!
Bought it for a gift. Enjoyed it very much.
