I used the cockpit that came with the plane and only printed an insturment panel and glued it in place. I did add a oxygen tank behind the pilot. My Spitfire is electric and I used a E-Flite Power 60 with a Thunder Power 6s 5000mAh pack. My Spit came in at 9 3/4 Lbs and is still a floater with the flaps down.
