The structure of the Schumacher is same as that use in BMT 1/8 on-road many years ago. The structure is similar to the 2 speed transmisshion now we are using but it use a click ( fly-weight ) to lock with the pin in the housing of 2nd speed and 3rd speed instead of centrifugual shoes. When the 3rd speed engaged, the click of the 2nd speed will rub with the housing ( rotate in reverse direction as the 1st gear ) of the 2nd speed gear which will cause power lost.
