What each maker states

• Where the makers' drawings differ, the model takes the largest stated, so a mount made to it clears every maker's motor (ADR 0134 row 4): shaft length E 18 mm (Johnson Electric 18, Mabuchi 13); rear boss height hr 3 mm (Johnson Electric 2.8, Mabuchi 3). Check your own motor's drawing where it matters.
