Doesn't a B-29 need something like a 10,000' runway for upping? How long are the runways in Aces High? Just make it so B-29s can only up from sea level airfields with 10,000' runways. Would be a successful mission to just take off as it is now. Maybe could have remote B-29 fields 200 miles away from another airfield. That would be a pretty big map though.
I think B-29s would be fun. The tailgunner position wasn't remote controlled and had a gunner. .50 cal x2 and a 20mm cannon...not bad for defense if the remote control problems with "coading" couldn't be worked out for the other gun positions, like with the Arado guns fired by periscope view.
I don't think a radial engine plane could go as high as a block style engine, like the 109 or Japanese equivalent KI-61 "Tony." P-51 could get there. B-29s could cruise at 38,000 feet, but how long does it take to get to that alt? Think how neat it would be to run into an enemy squadron patrol at 30,000 feet.
Man that would be fun!!!:D
