could also go with a different prop, but this is one that works: https://www.apcprop.com/product/15x10/

Calculations - found with Propeller Static & Dynamic Thrust Calculation

At take off, static force is 1.24kg and with a plane with a max weight of 3kg that is more than 1/3 of the weight

1.38*3=4.14kg that it can lift - account for error, 4.14-4.14*0.26= 3.06kg if the calculations are off by 26%
