The “What Other GA Aircraft would you like to see” has been around forever and shows how interesting and eclectic the communities tastes are. I am fairly new into warbirds here but as an retired (40yr) military aircraft engineer the genre has become my absolute favourite. Just to get the ball rolling I list a few of my top picks:
DH98 Mosquito - a must for me.
Bell P39 Airacobro might be interesting.
Blackburn Buccaneer S2B - just imagine sneaking up on all of those fancy carriers at 50ft and 550kts.
Handley Page Victor B2 (although a version swappable between the bomber and tanker fits might increase the appeal for IFR of the Bucc)
Might be hard to get access to, since only one original Kyushu J7W1 Shinden (Magnificent Lightning) prototype still exists, and is not in flying condition. The sole survivor is in the collection of the Smithsonian National Air and Space Museum.
I would love to see someone do a Lockheed Ventura. It would go great with the AH Lancaster and upcoming AH B-25J Mitchell. The Ventura was real handful and quite the hotrod twin bomber. I would love to see a really well done Hawker Hunter, Gloster Meteor and a CF-100 Canuck with high fidelity cockpits.
