Folks-My Nieuport 17 pulls to the left as soon as is starts picking up speed and is very difficult to control. On landing it will land straight and then as speed drops it will suddenly vier off to the left. What Open Plane parameters affect ground handling?? Thanks! Ronin IP: Logged |

STRAIGHT WHEELS! Even a degree off especially in the tailwheel can cause terrible ground handling. Since you only have the problem after you start to slow down this is the first thing I would check. Also make sure wings and stabilizers are lined up really good and you have your airPts in the proper places. If they're not you will get more drag on one side than the other and veer at higher speeds.. Make sure your CG boxes are lined up with the plane parts and the CG of the plane is in a reasonable spot. If the plane is too heavy in the tail it can swing around like a pendulum and get out of control on takeoff. TS IP: Logged |

Ronin, Ive experimented with another tactic. Add weight to your wheels and subtract that added weight from the Main fuse weight. I dont know how this affects flight, but it makes ground handling better.IP: Logged |

Another thing is not to get your CG too far aft. When the plane is real tail heavy the tail wants to swap ends with the nose. As the plane slows down, the rudder loses lift, and inertia becomes more powerful than the lift required to keep it straight. If the CG is closer to the main gear, the plane will be less prone to this in ground handling. A ton of trade-offs here, huh?IP: Logged |

Great tips guys! Thanks! I'll go wallow in Open Plane for a bit and check the above!Thanks again, Ronin IP: Logged |

Straight wheels is definitely one thing. Especially if they point outwards you'll find yourself in a plane that's very difficult on ground. Slightly inwards is less bad than slightly outwards.A lesser thought of problem, that's very difficult to tune well, is the shock absorbers. I've found that planes with both too stiff and too squishy shock absorbers tend to be difficult on ground. Just experiment with the dofSpring's and dofDamp's, and hopefully you'll come up with something. Unfortunately I don't have any rules of thumb to apply.
