I have hpi nitro mt1.I had a hpi 18ss engine installed [very fast].First run after brake in .I striped the teeth off of the spur gear,a 52 tooth[1m]hpi.every thing seems lined up. Can I get a stronger gear than the stock plastic? And what does the different number of teeth on the gears do? thanks bigpic.https://www.rcnitrotalk.com/forum/newthread.php?do=newthread&f=9#
