Ultrasport kit helicopter

I was hoping that I could get some advice on the Ultrasport Kit
helicopter, in particular on REAL build times for the 331 and 496??. I
have been told that the Rotorway is approximately 800-1000 hours, and
that the ultrasport is far quicker at about 300 hours. I am from the
UK, and there are no ultrasport helicopters here.
Rotorway is the only kit helicopter accepted and on the market in the
UK.
I would like to hear from anyone who regularily flies these machines
with the new Hirth engine?

Thanks Guys
