What is the best Prop size for 2s1p setup?

[Leo]

I got this ->HW18A ESC + JH2812-1534KV Brushless Motor from JH.
I fix it in my small profile biplane (flying weight ~350gms) with 2s1p 1300mA setup. The prop was from GWS EP8043 at first, then I changed to EP8060 (EP9047 not as good) is fun to fly around but still not enough pull for big loop. The current is ~5A. Anyone has experienced with EP1070 or 9070 in similar setup? Will it be better?
Thks for the advice.

i cant comment for sure on your setup, but your motor seems like it is very high kV, 8060 might be fine. i'm also new to planes. i'm running 1000kV Esky, 2s1p 1200mah and i've tried 1047, 1080, 1180, 8060 props for my E-starter. the best so far is still 1080. I might want to try 9" props next, because 1080 gives me very short fly time. 8060 was too weak to pull anything thru with my low kV motor.

Tested EP1047, result not good. Back to EP8060. Will try 9060 if anyone want to exchange the prop with me.
