The AXI can draw 60A... so the CC45 might be too small. But the propell-numbers Ed gave you calls for far less Amperes. The AXI might use a 18x12 propeller on 6S to get all the juice from the motor, but you don`t need it!
The good thing with the Jeti Spin is the onboard switched BEC which will supply enough to run all your servoes, saving the need for an UBEC or separate RX-battery. Both money and weight saved.
I would have aimed for at least 700 Watt, and this means you have to draw appr 35 A from that AXI on 6S. This is only half the power that motor CAN deliver. I might have choosen the 4120/18 instead... 90 gram less weight and suits your 6S battery well. And it is able to deliver more than 1000 Watt.
As long as we say your max Amp-draw is 40 A your 6S5000 will give you 14-20 minutes flighttime One of my operative acro-planes draw 44A max from 3700mAh batteries, and the flighttime is 10-12 minutes and still have juice left when landing.

Yes, the battery is heavy for such a small model, but I have a feeling it will work anyway. Save weight choosing the lighter AXI, and use as light servoes as possible without using too weak servoes.
