While tried to screw J2 Motor Mount on J2 Motor. I was having problem to screw all 4 screws on and the holes was disalignm to J5 Motor screw holes. https://drive.google.com/open?id=1Z_nCLpG018-28HbPJdh_bXN2dxL9KZTYI have to grind it manually.
Thanks for all your hard work to keep up the quality of the parts. Just wanna help to make sure issues not re-appear in future aluminium kit.
