Just been looking at the manual ....
First impressions
a) it's a 3 gear transmission

b) it's not as robustly designed as Fabs version
c) it's going to be well over £200 when shipped with duty
d) doubt many people will be running one in the UK / Europe so will struggle with set-up help (nothing new for us Kyosho fans)
Like the idea but if it was me I'd be pestering Fabs for a place on his waiting list.
I have my own ideas regarding a mid-motor RB5 ... think CR2 with Kyosho bits bolted on then your getting very close
