Thats Aussie dollars not US. And I was basing that on the modeltechs but I don't know how much the novaks will be. I'm guessing that it will be somewhere around $160-$180 for the esc and $120-$140 for the motor in US dollars. Not that cheap, but considering nearly zero maintance except bearings and they'll run forever if well cept it's worth it. In the end it should be close to $500 Aussie. But it will also depend on the exchange rate, whether it bombs again or not.
