If you're completely hooked on Hacker then I apologize in advance for straying off topic, but Neu often gets some F3A worthy motors in the closeout section of the website. Also things come and go before they get a chance to change out the inventory online, so good to call (that's how I got my new Neu, called and they just happened to have the perfect motor for my plane at ~30-35% off):

Right now there are 1515/2Y motors for sale, with/without fins, with/without gear boxes - $150 w/o gears, $250 with. Can buy a motor without a gear box and have them install the F3A gear box to save some weight.

1515/2Y is 1100kV, 1515/3.5D is 1200kV, Hacker is 1160kV.
