Angled Pusher Prop Question

1,611 xiaofootball  4.9 years ago

Are there anyways to angle a pusher prop without causing the plane to go backwards?

For one of my test designs, the pusher prop is mounted high, causing COT to be above COM. This configuration generates a downward pitching moment on the plane when thrust is produced, making taking offs and flying difficult. To neutralize this pitching moment, I figured I'll angle the prop upward to introduce a downward component in the thrust vector. But it seems that when the prop is in pusher mode (reversed), applying any angles other than 0 in the X or Y axis will cause the prop to operate like it is in pull mode. In other words, my plane goes backwards just because I angled my prop!

BTW, I've already tried the following solutions but found them to be unsatisfactory:

  • Reverse the prop 180 degrees in the Z-axis. However, this causes the hub side of the prop hub to stick out like a sore thumb. This looks extremely ugly and ruins custom prop spinner, especially if Blade T2000 or Blade T3000 are used. (Is there a way to disable hub mesh that I am unaware of?)

  • Use a rotator. However, the angle of the prop has to be manually set every time the plane is flown. All I want is a fixed angle that cannot be changed.

Perhaps the devs could add a new attribute for prop engines that allows manual setting of the direction of thrust?

    If the prop has a negative pitch when it's straight then when you tilt it give it a positive pitch

    There is manual setting for direction of thrust, it’s in the settings for the blade pitch change it from auto to manual
