As we have established, there are many things that can go with radio control helicopters, but most of these can be fixed without too much problem. As well as the radio-related issues we have discussed, there are also things you can check if you experience random tail jerks.
There are a number of concerns such as tail jerks, wags or spasms which can happen from time to time and can be attributed to the gyro. The gyro needs to be just right, i.e. not too sensitive, nor too lax either. This might be more obvious during fast flight when the tail is more sensitive anyway. You need to watch your rpm’s when attempting any aerobatics, especially if you suspect there may be a problem. You may just need to decrease your gain slightly.
Another common problem occurs when the gyro is not mounted properly. The gyro may not be secure and you should use the base to mount it on a horizontal surface. Only use the gyro tape which is designed for use with your gyro. This may seem obvious, but may be the cause of your tail jerks.
The final gyro problem we will consider is high frequency vibrations which can easily interfere with the inner workings of the gyro and affect its performance.
