Looking at the first picture and initial information it looks to be very much an evolution of the F104v2 but with a new front end, wider motor pod and more link settings.
Tamiya has announced some specs of TRF101 F1:
The front arms are 2.5mm carbon fibre rather than the plastic used on the F104
Servo can be placed standing up or laid down
The aluminum motor mount has "extended lateral width"
Carbon rear shaft
Quick mounting position from three locations before and after (No idea what this means, maybe the front suspension mounts?)
