This incredible video comes to us from our friend Tbobborap1, who filmed the giant-scale model at an RC event at the Royal Air Force Barkston Heath base in Grantham, Lincolnshire, England. Our mystery plane is of late WW II vintage, was carrier-based and flew for the United Kingdom, Canada and Australia. It was especially prized as a submarine-hunter. Make your guess in the comments section, then watch the video of this outstanding scale model in flight. Kudos to the builder and pilot, who as of this writing have not been identified.
