I have an "old" RRR WC edition (with some upgrading on it, of course

) and I was planning to move to the R4.
Now I have many doubts and I'm really wondering about it, since I don't see as much interest on R4 as I was thinking and moreover, surfing on several on-line shopping (let's forget local dealers

) I'm seeing there isn't so much diffusion of even normal spares, while there are many discounts (dismissions?) on all Kyosho parts for the other RRR cars.
What's happening at Kyosho premises?
Very strange situation since all the new baby premises were good, low center of gravity, reduced differentials, good accessibility...
