Thunder Innovation 32 & 36mm Pro One clutch

Thunder Innovation have released a 32mm steel Pro One clutch system for Kyosho and 36mm steel Pro One clutch system for Durango buggies. The shoe design provides much more contact with the bell and there are three types of flywheel for different track conditions. The light aluminium version is used on high traction surfaces and to provide a little extra bottom end snap from your engine. The medium & heavy versions are used to tune for low traction surfaces, as well as to smooth out low RPM power delivery on engines that have a strong bottom end hit.
