I’m interested in this updated set, which can be found e.g. here:

However, as this is a DC engine that ”easily can be converted to AC”, I’m a bit curios on performance:

- Wheels in K and C track turnouts?
- Feedback at S88 modules, will all wheels provide feedback?
- Other experience?

I have the same model. I had mine converted by the dealer (Roger Suter Meggen). It works relatively well, but has seen very limited time out of the box.
The original model was marketed under the new Lima Expert series. I don't know whether this new model will have the exact same construction or whether there may have been changes in design and electronics.
I probably will wait until the model is out and then try to find the instruction manual and compare it to the one I have before I decide on whether to add this new model to my fleet.

I must partially correct my previous statement, there was a stuck coupler that wasn't moving freely. Now that it's moving freely, derailments continue only on some critical K double switches (2275).
I have to say that also other trains, even with AC wheels, sometimes derail on those switches and I don't understand why.
One critical point, at least in my consist, is that the couplers are too low, touching into center studs on switches. Besides the couplers can be inserted improperly (i.e. misaligned) causing electrical problems.

About AC wheels, the original DC wheels are 10 mm diameter and 23.6 mm axle length. I have not found any AC wheel of this size, the closest is a 10.4 mm diameter, 23.8 mm axle length for Kleinbahn, model number 83 from Benno002-22 on ebay. I tried to insert a 10.4 mm AC axle for Piko but no way, it's too long and plastic of the bogie is stiff. I didn't try to force the axle inside, if the bogie breaks no spare parts.
