This is a very good video explaining all Kawai actions. I posted it because I think it's especially helpful for anyone new getting into digital pianos. Good to clearly see how these things work IMO.

I don't think Kaiwa is going to like you referring to the RHC as being 'Semi Weighted'....

Thanks for sharing, good to see how they work! Even here the RHC is described as semi-weighted - totally agree as it's much lighter compared to others.

I'm not sure where she heard that, but it doesn't look to be true, at least based on this comparison image I made:

Right. Semi weighted doesn't mean lighter, it means there's no hammer mechanism.

One would need to measure, as those pics may not be quite to scale.

I think you can just confirm that the back of the black keys is lined up at the same time as the front of the white keys to confirm the scale (or have it be good enough).

Here, I think what happened is that U3 just mistook the GF Compact for the GF2?

I appreciate that Kawai is not calling their top actions "hybrid."

Interesting she mentioned GFIII having "faster repetition".

The technical differences between GF, GFII & GFIII are listed here.

There's lots of comments about GF being slow (compared to RM3II) at the end of this thread.

GFC was shown some love here (with respect to GFII), but said to be difficult to play ppp here.

I don't remember seeing any negative comments about GFIII. I presume it's generally the favourite?

It's all to scale, overlaid and precisely lined up (black key, etc.) - definitely the same length and pivot point. All previous discussion has pointed to GF3 being the same length, I'm not sure why this particular video claimed otherwise.

Yes, GF, GFII, GFIII all share the same key length.

Kind regards,
