The whole purpose for combining motors is to gain a higher output power.

Let's compare motor power specs for a second:
Bosch Drill Motor - 455W Peak Power
Chiaphua Motor - 321W Peak Power
FP - 140W Peak Power
Globe (no gearbox) - 63W Peak Power

So by combining the Chips and the Globes:
321W + 63W = 384W

Note, this is LESS peak power than the Drill motor has alone.

So... it is somewhat silly to use this combo, when the Drill motor by itself is better.

For more information on motor combining, and gearbox theory and physics... please search the forums.
