13x8 is pretty standard. If you do not have a watt meter, you should purchase one. Watch your amperes and wattage as you give it more throttle. If it goes over and above your ESC limits, you should use a smaller prop or a large ESC or motor.

I think the model weighing at least 16 lbs.
At that stall speed will be 27mph.
Required to fly at about 80-85mph. APC 13x10 with a 10.300 rpm.
And consume around 1900 watts.

6s is necessary for a motor of 480 to 600 grams with 560 Kv. ESC 90-100A.
For necessary 8s same engine but with a weight of 421 Kv., ESC 75-85A.

would be equal, but with an motor of around 340 Kv.
, 51A, esc 60A.
Maybe 4000 ma are enough for 4minutes.

If you can fit a larger diameter propeller, then we can get better push, if you can, a 13x10 3 blade work better, but occupy the same rpm. and a little more a amperes.

so get a 3 blade 13x10 prop and run it on 12s with a low kv motor? they sell 295kv or 245kv as the lowest.

You best chance is with 295 Kv.

What brand of motor, you mean?

Im sorry, this numbers are for 10s.
For 12s is a motor 280Kv and around 42A.

Maybe with tacon big foot. is around 11.000 rpm and 45-48A.

I got the 295k motor today and the 120hv esc

I need to figure out which prop i can use on 12s. I guess if i go with a lower size prop it should pull less amps. I can only do 12s, I dont have any other batteries. If i can prop it down with 295kv i rather do that than buy new batteries.

Im going to experiment with a 3 blade 11x8 and 12x8

on 12s at 295kv sounds about right. I have 120amp esc so I think it will have the punch.

I think your motor may well up to 13x10 propeller.
But very good test before the 12x8 propeller fot check ampers and rpm.
and so see if you can do the test with the 13x10.
