Thats totally freaking cool and a bit of a mind job also lol! Makes me proud to own a castle product even if it is rebadged by HPI. I wonder what big ass companies like Traxxas use to make all their brushless systems in bulk?

Im confused by the oven. Isn't the solder already placed by the stencil printer? Is it a special solder that stays in paste like form to install components and then once heated and melts and cools, it turns solid once? How can those delicate circuits survive in that high heat which im guess is like 300+ F?
