Try gretting more thrust from the propellers at lower throttle speeds

In the aircraft.cfg change:

[propeller]
beta_min= 5

If that's still not enough try 10

I am not familiar with the HS748 as a real aircraft, but i do know that on the F27 which has the same engines this behaviour is also present in real life.

The propellor only starts to produce thrust (torque) when the engine rpm reaches approx 10.000 - 11.000 rpm. That is the stage at which the blade angles start to increase, thus creating torque . So between 7.000 (gnd idle) and say 10.000 rpm the prop stays in ground fine pitch. This is because the Dart engine does not develop enough power in this region to sustain itself and drive a "torquey" prop without overheating.

So it is actually quite realistic. Yes it makes taxying a bit more difficult, but that's what it's like in real life as well.

(I know this because i have the real life experience on the F27, job-wise)

Surely, and I commend them for their fortitude and extensive research into the aircraft.  Any designer that puts that much effort into a project should feel extremely pleased with it.

However, for those of us in the FS world that have no means to judge inertia by the seat of our pants, or to have a full view of the aircraft's movement at the turn of a head, problems such as these go a little farther beyond what is necessary.  For those that actually fly the real aircraft in life, it seems to be a little more pertinent to have the actual flight dynamics match up, but for me, I would want something a little easier to control on the ground.  Having an aircraft that moves oddly on the ground would make me want to not even attempt a takeoff, let alone fly it around.  And indeed, I have given up on some promising-looking aircraft for just this reason.  It isn't anything against the creators, exactly, just the fact that I want to have as smooth a ride as possible.

BUT, if you like that sort of stuff, by all means, keep it real!
