One of these motors with a 7x4 Cam Folding prop, 20 amp ESC and an 850 mah 75C 3S battery would do the job nicely. You will need to move the servos and RX as far back under the wing as possible and switch to mini servos if you haven’t already. Everything needed is available from the same site as the motor.
