Flying RC helicopters have become my daily leisure activity for a few years as I have found it the most exciting game. But after flying it for a couple of months, my Helicopter stopped flying and kept spinning. And I kept wondering why does my Helicopter spin in circles?
Since I love my Helicopter the most, I started searching for the issue, and guess what! I could actually fix the problem by myself. And in this article, I am going to let you know how I did that.
Why Does My Helicopter Spin In Circles?
A helicopter may spin in a circle for various reasons. Among them, the most common are damaged gear and the wrong assembly of blades. Let’s know these reasons in detail.
What Causes The Spinning Issue?
There are some common technical issues that cause the problem. If your helicopter is spinning only instead of flying off the ground, then your Helicopter must have any one of these problems.
Worn Tail Motor:
There are two types of helicopters based on the motor. The first one uses only one main motor that rotates both the blades onto the top and tail. The other one includes two separate motors to rotate the upper blades and the tail blade.
If your tail motor has worn out over time, it is possible that your helicopter won’t fly and keep spinning. Since the fans of the tail are also important to fly a helicopter, you may need to replace the tail rotor to work properly.
Wrong Assembly of the Blades:
If you look closely, you will find that the blades of the top of the helicopter have different markings on them. Usually, in the case of a four-blade heli, the upper blades are marked as A and the lower ones are marked as B. By any chance, if you have misplaced them while assembling, the spinning effect can occur.
In most RC helicopters, the motor and the blade holding stick are connected with four gears. As the teeth of these gears are really small and are always colliding with each other to rotate the blades, they are prone to degrade over time. This is one of the main reasons for this spinning or toilet bowl effect.
How to Fix the Spinning Effect?
To fix your problem, you have to find out the damage first. For you, I am giving a step-by-step guide in this article. If you follow these steps, you will be able to find the problem and fix the issue.
Step 01: Check whether your helicopter is charged fully.
Plugin the charger cable in your heli. The charge indicator LED will turn off or change color when the heli is fully charged.
Step 02: Turn on the helicopter and set the throttle up in the controller to fly your heli.
Step 03: Check your tail fans.
If your tail fans are not rotating and there is a separate motor, you will need to replace the tail motor. Follow the next steps if the problem still suffices
Step 04: Open up all the screws outside and take out the canopy and face of the helicopter.
Step 05: Look for the gears below the heli
Step 06: Check for any damaged gear or you can replace all of them with the new set
Step 07: Assemble the parts together again.
Step 08: Try to fly your heli again.
Why Do Helicopters Spin Without A Tail Rotor?
Answer: The tail rotor helps to cancel the torque created by the head rotors. This anti-torque phenomenon helps the helicopter to fly upside. Without it, the helicopter will spin only.
What Way Does A Helicopter Rotor Spin?
Answer: It can rotate both clockwise or anti-clockwise. There isn’t any specific direction for it.
Why Is RC Helicopter Not Taking Off?
Answer: Apart from the above-mentioned causes, a weakened battery or jammed gear can cause this problem.
It became really upsetting for me to wonder why my Helicopter spins in circles rather than taking off and flying. If you are flying an RC Helicopter, this problem is a sure thing to occur. But now you also know how to fix it.
My final suggestion for you is to grease up the bearings, joints, and hinges. If you put a few drops of oil in the joints, the heli will fly smoothly without any hindrance. Try to learn safe landing first, it will save you from a lot of trouble.
