CS didn't use costume ground friction as some top add-ons do, their solution on FSX/P3D's buggy standard ground friction is to make engine more powerful as soon as it left idle, you can see it from FuelFlow, at ground idle, the FF is about correct, but as soon as you push a little throttle, the FF goes about twice high, that makes "cruise taxi" with just right amount throttle almost impossible.
To be fair it's common practice before costume ground friction became a thing, like on iFly 737/747 and even the new Feelthere Ejets v3. Just hope CS could do better than it is now.
