motor/battery and prop configuration... any suggestions!

Hi all... Hoping someone can help out a noob to electrics!

I'm waiting for my new GWS F4U Corsair to rock up and have been busy making sure I have everything to get this bird built and flying.

The Corsair comes with the EPS-350C-BS motor/gearbox and I'm planning to use 9.6V 8 cell AAA 650mah batteries and a new GWS ICS300 ESC.

By the looks of it the kit comes with a 9070 and a 1060 prop, plus I have a few spare 9070 props as well which I was hoping to use. How do you think this motor/gearbox setup will work with a 9070 prop?

According to the GWS website it should be safe to use a 8043 which will run at 8.9amps. 8060, 9047 & 9050 run between 10.6-12.6amps but 9070 isn't even mentioned there. Further down the list though under the EPS-350C-DS setup a 9.6v spinning a 9070 runs at 8.7amps. I'm assuming the BS/DS is different gear ratios?

Any comments would be much appreciated.

tried a 9070 with 350c and b gear before, it was pretty fast and powerful, but I tried it on 2s lipo which is only 7.4v, going with 9.6v and 9070 might kill the motor really fast.

Yeah I was thinking it would... how does it affect the amperage if you only fly at half throttle? I'm not planning to do any fast flying for a while anyway.
