Will have a look at the Kamtec shells, I didn't know they produced one for the Turbo Optima.
I've not raced for around 4 years now, but a vintage race does appeal.
I think I'd be concerned about things like chassis rails (I've hardly ever seen genuine Kyosho ones come up), and some of the drive train parts really. I've managed to collect quite a few NIP spares along the way (got a bit carried away buying parts
), so a few areas would be covered.
It's been a fun and enjoyable build to take it from its original state to this, I'm quite pleased with the end result.
