Recently dug out my old and bashed Kyosho Mad Armour, and considering an electric conversion, stumbled over this forum. Now I'm waiting for the motor mount and diff. 🙂 Will have to go over this again once I have everything else. Two questions if anyone still follows this, to save a bit of time: What size pinion did you use in the end on the motor, and where is the best place to get one? Thank you.
