I've not had any glitching issues with my Falcon however that's not to say I haven't with other helicopters. When I first finished building my Eolo helicopter I had intermittent glitches that eventually caused a crash. Generally glitching can be a real pain to diagnosis and find but it can be done using the process of elimination. In order to do this you will need spare parts, i.e., receiver, servos, speed controller and motor. In most cases glitching can be traced to bad solder joints, broken wiring, faulty equipment, and poor placement of electronics. Since most helicopters have limited space to mount electronics it can be difficult to move things around so one must use their imagination. Glitching can be identified as sudden loss of control, twitching servos or motor, reduced range and delayed control response. Sometimes glitching can be found without having to fly your helicopter, just sitting on the ground it will "glitch". I've found my Falcon to be very reliable from day one, however, I did once have a glitch probably caused by radio interference but I never was able to pin point the problem. All that being said, you will have to try and diagnose your "glitch" by trial and error. If say it only happens when it flight you might be able to eliminate the receiver or servos if say the motor cuts out momentarily or shuts off completely. Unfortunately the Falcon speed controller is probably being taxed to it's limit with four servos and gyro. Since the Falcon does not use a switching battery elimination circuit it can be overloaded which can cause all sorts of problems. If a servo is pulling too much current because it is stalled or binding it can pull more current than the speed controller can apply and this can lead to momentary power loss. This will be seen as a glitch if the power loss only lasts a split second. If the antenna wire is wrapped over or overlapped this can reduce the range and cause glitching. Cold solder joints on the motor wires connecting to the speed controller can cause glitching as well. Unfortunately there's no simple one step method to cure glitching, it takes time, effort, and patience. My Eolo problem took nearly six months of tinkering before I finally found that the speed controller couldn't supply enough voltage to the electronics to prevent glitches. I ended up replacing the speed controller with a very expensive one that had a switching BEC and that cured my problems. I hope maybe some of this helps those with glitching problems. Don't give up, they can be corrected!
