2 Speed transmission Question?
 

These two transmission are the same basic design but the second one has an extra 4:1 reduction after the motor. My Question is can you remove that 4:1 reduction and use it without? ratios are 1:4, 1:16 and 1:16, 1:64. Would like to buy the one with the reduction but be able to experiment with and without the reduction for the right speeds.
