I have built over a dozen Tamiya kits and all of them had philips head screws. 3racing FGX was my first kit that came with full hex head screws. As a result, I ended up building the whole car with an L -wrench.
When I was done, my finger tips hurt so much! Since then I have purchased proper tools and it's been a lot easier on the fingers when I install new parts on the car.
