I just took a hacker A60 18l out of a 89inch slick (50 to 60CC size plane) and put in the hacker A80-10. Both with a 24x12 prop. The difference was night and day. With the A60 the plane was lethargic at best. It would 3D and had pull out of a hover but that was about it. Slow top speed and I got my but kickd by a 60CC power one
. Plus the motor got VERY hot (150+ยบ range after each flight) running a 12s 5300mah setup. Put the A80-10 in the plane and not pulling many more watts but the power out put has doubled. This plane feels like a foamy now
It has a awesome top speed and has just stupid hover pullout. It was SMOKE the 60CC powered slick now!!!!!! CAll Aero-models and they will set you up with the right system needed for the plane. It was there recommendation to put the A80 in 89 slick.
