Hi guys, after an awfully long time i got my Panther G out and did a little maintenance before running her. I decided to change out the stock pinion gears on my waltersons to 20 tooth ones that were supplied with gearboxes.
Everything fitted great inside the hull, so i oiled them up and did an open top run to check there were no problems before screwing down the top of the hull

No problems occurred so i secured the top hull down and took her out for another spin, only this time there was a dreadful grinding noise, and upon inspection, the left hand pinion gear had lost 4 of its teeth, completely sheered off clean

The right is in perfect condition so I'm unsure what has happened, do any of you guys have any idea? And where do I get a replacement?
Thanks for any help in advance guys
