Re: B-25 Mitchell For me, it happens no matter how fast I hit the water. I can just roll it slowly in and it'll still error. - - - Updated - - - Noting that yes, some multi-engine planes did have this issue, a lot of them didn't, as it was common practice to initially build the plane so the propellers would spin opposite directions, for example, going from left to right looking from back to front on the plane, the propellers would spin as below: CC-C-CC-C or CC-CC-C-C or C-CC-C-CC or C-C-CC-CC for 4-engines, and either C-CC or CC-C for 2-engines. CC being counter-clockwise, and C being clockwise. This reduced the aircraft's turning unintendedly. Most B-17s if I remember correctly, had this put in place, so it was easier to fly. It might have only been the training planes, or it might have been something they did as an after-thought/"aftermarket" thing, but I do remember seeing the props spin opposite directions on the real things at an airshow once. Some went same-direction, some went opposite directions. I wouldn't say it's something that needs to be fixed, since I've seen them both ways, but if someone wants to make an edited version of it where the props rotate opposite directions so it doesn't propsteer (I forgot the technical term), then I'd like a copy of it, so then I'd have a copy of both types.
