Have built the P-40, F4U, P-51 and finally the P-47. I added ailerons to the P-47 and put in a 180 size motor with a 5x3 prop. It has a 2S 480mA LiPo. It is Extremely fast and very responsive with the ailerons. I used a single aileron servo and flexible pushrod taped to the bottom of the wing (the servo was mounted in a cut out in the center section). The MAN article recommended the Astro Flight geared motor upgrade but the 180 was the same diameter as the original 130 and just a little longer. I would highly recommend it (especially sinse the 180 motor was $9.99 and the astro flight motor was $80!).
