I got a problem

5,370 Bursucu  7.6 years ago

I just made a Yak-15P but it rolls to the right continuously and the CoM,CoL and CoT are completely in the middle and the wings are the same on both sides. How can I fix that?

    The CoT has to be either right in front of the plane (propeller), or in the rear of the plane (jet engine), the CoM has to be in front of the wings, and the CoL has to be in the middle of the wing itself.

    @Ctracerx2 ATTACH POINTS! That mirror tool gets me every time with that. I spend hours building one side, mirror the parts, and cackle like a lunatic when I try to lift off and half of my plane falls to pieces like the glue got wet! I don't have the MP mod yet, but I will.

    @Alex23 I removed the prop, still yaws to the left quite a bit. I wonder if it has to do with the tail surfaces being too small to combat the low COT at slower speeds.

    @Ctracerx2 What did you change to fix it?

    I tried reversing the rotation of the prop and now the plane rolls left. I think it's the prop :) Try installing a second one behind the first and reverse it's roatation, that might counterbalance things. Or just use a modded jet eninge for the inlet. Good luck, she sure is a beautiful plane!

    @Tully2001 ok it was a small part which had more drag and I removed it but it still does that
