Hi Steve,
The second model maker has now been awol for 3 weeks, I suspect these guys
have heard from the first lot that I want attention to detail (not easy to
find here.)
I understand all the flywheel issues you brought up. Surely someone has
addressed this issue before? I am sure that the std 302 flywheel is designed
to work well in heavy US cars and there should be someone who has figured
out the best weight for a tiger given its weight, 1st gear and diff ratio.
SOMEONE OUT THERE PLEASE HELP!! I tried looking on tigersunited but the
server is still down.
cheers, derek
