- Fan motor

I use MK07-2.3 (didel) with 2 cell LiPO(7.4V). When I use MK07-17, I got good suction power than 2.3.

Although, the motor is broken sometime because over load (or too high speed).

-Fan rotor design

I don't have knowledge of fluid dynamics. Therefore, I made 10 fans and test suction power

The result of this test, one has 25g power, the other has 45g power. It is amazing for me. I knew that fan design is very important.

-stable control system

It is just a coincidence that even once Que didn't crash, I think. in training, he jump over the wall sometime...

Que depends largely on control by gyro, I think he can't run without gyro.

But it is not only for que, I think it is common sense for Micromouser.

I think, the mouse with suction system is difficult from the viewpoint of control the slip, because suction power is not stable while running. Therefore, the slip occurs suddenly.

If you will make suction mouse, you should take care 3 things.

- The vibration caused by fan

- Battery capacity (the fan motor current is larger than you think)

- Get spare fan motor (I killed more than 10 motor.)
