Using the TBM-930 [aircraft-tbm930-improvement] I find it has great turning radius and control at low speeds. However once I am rolling out for take-off over 25kts the plane starts swerving left and right…very difficult to control until I’m going over 80kts…then I have good rudder authority. This also happens with the vanilla TBM-930. Anyone know how to fix this?
Well, knowing the mod community, however, it might just be like the real thing or you “might” just have your sensitivities on the rudder controls set too high, where you only tap the rudder and it generates high degrees of deflection. Also check if you have the rudder assistance to the “off” position. If it’s fully “on”, it’ll barrel you straight down the runway nomatter what, i dont know if there’s a partial position, i just have it turned “off”.
The torque of the engine might be working on the nosewheel as the aircraft is gaining speed and lift. over 80kts you have more rudder authority and the nosewheel becomes the passenger instead of the turning force.
Thank you for your response.
All that you have mentioned has been checked. As for the settings in sensitivity, I’ve tried many different adjustments…can you please give a settings suggestion how to tame the nosewheel wildness between 20-80kts.
Do you have nose wheel steering bound which might interfere? Flying the TBM regularly, but very stable take off runs on my side.
No I don’t have nose wheel steering bound to any of my controllers, just rudder.
I’ll try adjusting my flight_model.cfg see if that helps.
find your flight_model.cfg of the aircraft under its folder;
ie. E:\msfs 2020\Community\aircraft-tbm930-improvement\SimObjects\Airplanes\Asobo_TBM930
BACKUP original file then find the section titled:
[CONTACT_POINTS]
Find the line: [change 8th value to 30]
point.0 = 1, -2.3, 0, -4.18, 750, 0, 0.5, 20, 0.21, 3, 0.5, 0, 0, 0, 0, 0
This reduced the mod’s over turn radius while restoring stability on a straight ground roll out and allowing for decent turn radius.
You can lower the rudder pedals sensitivity as I did to -30 -30, this gives more controllability.
You can play with all these values and see what works for you.
With the Logitech G940 pedals i noticed that the -30% to even -40% was nescessary to get proper control without swerving all over the place.
Now that i have the Thrustmaster TPR pendular pedals, the sway in those is alot longer, so you can have more control keeping the aircraft straight. Sensitivities are set to 0 on this one… and without moving the rudderpedals the TBM 930 only slightly swerves to the left upon applying full throttle between those aformentioned 20 and 80 kts.
Glad you found the culprit! Have a nice flight… and takeoff! 
And likewise to you as well…cheers.

Does anyone know what each value is supposed to do?
