As promised, we will now be detailing the common causes of radio interference and lockout which can affect RC electric helicopters. Hopefully, some of these points may resonate with you and you can now locate and try to fix the problem, then you can get back flying again.
These are some of the radio problems you may encounter:
• If your radio antenna has touched something metal, this can cause interference. Also, make sure that your metal to metal screws are loctited, as well as the main shaft.
• If there is a rattling or vibration problem then this may be caused by a loose metal to metal connection somewhere. There may even be a loose connection inside your receiver.
• Check the bearings to see if they have been damaged in some way. Make sure the bearings in the tail gear are sufficiently greased.
• You may be getting some interference from somebody’s TV channel which is on a harmonic frequency. Or, you may be flying too close to another person who is on the same channel as you.
• The antenna may be in too close a proximity to other electronics.
• The receiver may not be securely insulated from the engine vibrations of your craft.
Finally, if all the electrical connections are fully secure, it may just be that you have low battery power on your receiver or transmitter. Make sure you are in a place where the antenna has the strongest signal possible and away from other electronic devices. If there is still a problem, it may not be radio-related.
