any recommendations on the replacement of the hot racing 44 tooth steel gear in replacement of the plastic gear? Looks like it's discontinued and can't find a replacement. Waiting for my ercm picco and engine from Robin in Canada so I can drop it in my savage x. Thank youWell turns out heres an easier fix now. HPI Octane gears are hardened steel and work as replacements. Hpi111167 and hpi111169. Pic courtesey of Llcoolskillet.
