I don't know much about turbines, but I thought they had to spin fairly fast. Might need a really good clutch system or automatic type transmission. In the links above, those engines were all spinning like 20k plus rpm, at idle. That is a pretty nasty clutch drop, and easing into it seems like a smoked clutch waiting to happen. It has to be possible, tractor pullers have done it for decades in full scale, and iirc I have seen a scale one on youtube somewhere. Perhaps with a deep gear reduction before the clutch, things would be more sane.
