Smaller recommendation for your 80xx motor mounts. Include the mounting hole pattern in the product description.
80xx motors do have different mounting patterns depending on the manufacturer. If those mounts are made for the leopard 8072 motors, than those mounts will not fit 8085-80100 motors from freerchobby, flipsky, Alien Power Systems etc.
Thickness of the Mounts (both for the 63MM and 80MM Motors) is 1/2 inch or 12.6MM - Alu 6061 and all threads are formed, not cut. Guess you know formed last significantly longer than cut threads.
Just a lot of stock I need to reduce. So want to make it attractive to sell it fast - this is all perfect stuff, never used and new. Only the two last MBS Matrix II Motor Mount sets are not perfect … I have the chamfer not nicely done, this is only visual…and will not impact strength of function - and I do mention it in the text on Etsy. However, they are my last, once their gone their gone. Seems like not many peoples use MBS Trucks for their electric builds.
