Do not use sharp tools and picks to install the belt on the 1/5th scale super-charger. The hook in this set works great! Also the straight point works great to lock the shaft for quick overdrive pulley changes on the supercharger. Overall a nice set to have in the toolbox for the odd jobs other tools just dont work well for. Set of four tools per kit. Use on any 1/5th scale application including; HPI Baja 5B/T, Losi 5IVE & others
