There have been and still remain a few problems with the build that RTR and myself are working to resolve. However I'd say the kits should be very easy to build from now on. I have no experience of building any other car, in fact the most I've ever done is change a wheel!
I think a competent home mechanic with a reasonable tool kit and a problem free tR1ke kit should be able to pop a tR1ke together in less than 60 hours.
I'm up to about 40 hours so far, but 10 of those were problems with my kit which will be ironed out for all future kits.
I've been promised that the lost time will be made up to me, by Paul at RTR, but no deal's been reached as yet!!
Already it's becoming apparent that the completed vehicle will be as light as you like!! And hence it should go like stink!!
