The losi box is very weak. Not a good combo for breaking in tough engines. I switched to the Ofna Truggy box and transfered the top of my losi box to the top of the Ofna box. I recently broke in a GRP .28, in the past .21 GRP's gave my Losi box a tough time even with heat, The Ofna box didnt even break a sweat, it never hesitated and always turned the new engine over. Not once did I have to turn the fly wheel over with a screwdriver because it was stuck. I did install the 4s lipo and deans wet noodle wiring throughout it. No starter box problems now.
