My spitfire runs a GForce 3542, 50 amp ESC, 11x5.5 APC prop, 5000mah battery. Wow this is a wonderful warbird to fly. Punch the throttle and she literally screams through the sky. The sound is truly amazing, especially in a dive. Flies smooth whether it’s fast or slow. Highly recommended for anyone who has an affinity for great flying warbirds.
