hi

i dont get it. i have read on like90 site that our motors are spinning in the wrong direction. they offer a flipIT mod that enables the motor to be mounted underneath the frame and this means the motor will spins the way it is meant to.

what i dont get is why it spins the wrong way, surely if it is set to spin a certain way, it should just spin that way!? what makes it change? how does flipping it over change the way it spins!? im confused!

Think about the gearing. If you flip the motor around, the shaft is spinning in the opposite direction with respect to the motor.

I dunno about the motors not being designed to spin that way....

The motor has a positive and negative terminal. In order for the heli blades to spin in a clockwise direction, you have to have the engine turn in a counter clockwise direction. The only way to do that, because of engine orientation, is to connect the negative to the positive and positive to the negative on the motor. I believe the brushes and motor are less effective that way. Flip-It enables you to turn the motor over and run it in the proper direction.

The rotor blades must spin the right direction, or you wont go up. The motor must spin clockwise to make this happen. The motors we use are designed to turn counterclockwise, that is, they are timed to run counterclockwise. When running them reversed, the timing is way behind where it needs to be, and this gives us less power, more heat and higher current draw.
Flipping it over eliminates all this.
