Why does my helicopter spin
This counters the torque applied by the propeller. Ask an Explainer Q:. I understand that a helicopter uses the tail rotor in order to stop the helicopter from spinning in the same direction as the main propeller, but how does a airplane such as the Cessna that has one propeller in the front stop the aircraft from spinning.
Replacing the motor may solve your problem if the gyro seems to be working. Check the trim on your transmitter. Ideally the trim should be in the center of the stick movement. You may need to dial in some extra right trim or you may find the trim is set too far to the left.
Check the user manual for the helicopter. You may need to follow a prescribed sequence before flying so the gyro can sync up with the controller. He has over 25 years of experience in the information technology field programming and supporting code.

Objectives Describe how force can be applied to move an object. Materials Per paper helicopter: 1 copy of the Paper Helicopter Template student on ordinary paper. Key Questions What can we change? The paper should be folded twice lengthwise. Have students make predictions about how the paper and the helicopter will fall.
Drop the paper helicopter and the piece of paper from the same height at the same time. What was the result a result could be: which one landed first? Part 2: Activity Discuss results. Which prediction was correct? Pose the over-arching question: What makes the paper helicopter spin?
Students construct their own helicopters and test them. Questions to prompt student thinking as they explore: What happens to the helicopter as it falls? Why do you think the helicopter falls to the ground? Why does the helicopter spin? Why does the helicopter drop slowly? Ask Questions for a structured or guided inquiry: Divide class into 4 groups and assign each group a question Question for investigation : What could we change to make the helicopter spin faster?
What could we change to make the helicopter spin slower? What could we change to make the helicopter fall slower? What could we change to make the helicopter fall faster? Ask Questions for a more open inquiry: If students are more experienced with inquiry, they may pose their own questions to explore. Independent Variables Ask: What do you think we might see? Students may share with a partner what they think will happen or they can draw a picture.
Students may draw pictures of their observations. Students repeat each experiment a few times to avoid anomalies. Repeat the process!
Share Have students demonstrate their helicopters and share the changes they made.
