Most of you guys are spot on with giving tips to use throttle to control the descent, keep the approach low and steady on the throttle until touch down.
Too many newbies bring them in like a hockey stick: steep approach, idle down too early, flare too short.

The TopFlite P47 and P51 are very predictable warbirds to practice and learn good techniques. Make them a bit noseheavy and you will see dramatic improvement on landing.
I've flown several spitfires, not the CARF, and find them to be floaters and like to noseover, not ideal airframe for newbie warbird pilots.
