Thanks to Eduard for providing more of their excellent aftermarket parts for IPMS USA review, and to IPMS leadership for sending it to me!
Here we go. According to the flight manual, the average Spitfire pilot will retract the flaps as soon as he/she is on the ground because the flap interferes with cooling air exhaust from the radiator, which leads to overheating on the ground. BUT, sometimes flaps must be down for maintenance, which is how Eduard approaches the situation.
This set is not for the faint of heart. it requires patience, dexterity, skill, and a lot of luck to pull off a successful installation. I get four of 10 on this one for my lack of the above.
HOWEVER, many will do just fine with it. Remember rule 1: Metal work hardens every time you bend it. Breakage is a way of life. if you try to bend things more than once, you MIGHT get a second chance.
SO, study your flaps, and develop a course of action!
