Default Normal to veer when taking off and trimming question?

Hi. I have the Saitek Pro Flight rudder pedals and the TM Warthog Hotas.
One thing I notice is when taking off using Nosewheel Steering that my plane will want to veer a lot and have to apply one of the pedals to straighten the plane. Once the NWS is switched to Rudder it eases off although still not straight usually. I have a fairly large deadzone using the windows properties as opposed to a deadzone in DCS axis settings.


So I am wondering if the veering to the side is normal particularly in regard to the NWS? I appreciate it may be wind, but just wanted to check.


I also have to do a lot of trimming once airborne to fly straight and level and it's a lot of hard work on a flight.
My TM Warthog is calibrated perfectly and again I am wondering if my pedals(rudder) might be causing an issue or is it normal to be constantly having to trim to keep straight and level?

My A-10 tracks straight down the runway without wind and no asymetric load.
Any crosswind component will require corrections due to the weathervaning effect.
A large deadzone isn't a good idea, try to set it as small as possible.

Do you need a lot of pitch trim for straight and level flight? With no asymetric load you shouldn't need any rudder and/or aileron trim.

The twitchiness of the rudder with the NWS engaged could be a deadzone issue with your pedals, and I always found in the air I needed quite significant and constant aileron trim in flight to keep wings level, but a larger deadzone did improve it considerably on my TM Warthog.

Concerning the NWS. Once lined up on the runway there's no need to use the NWS. Directional control is still more than sufficient.
The RW A-10 manual says for T/O; NWS as desired.

Everything's normal, enjoy your flight.

I could suggest to set a deadzone on rudder at pilots that faced signal spikes due to hardware poor quality like my Saitek Combat Rudder Pedal.

Normally you should switch NWS off around 80 kts, when the rudder gets effective

Also, if you read a little futher in the T/O checklist, it states:

"During takeoff, maintain directional control using nosewheel steering until the flight controls
become effective."

Additionally chapter 6-1 gives you: "The rudder becomes effective at approximately 50 KIAS"

At least in a C-160

The important thing is that on the DCS A-10 the rudders are becoming effective way too early. Below 20kts.
That's definitely sufficient to start the takeoff roll with the steering off.
