| The following is a product overview of the RCHover 'Glitch no more' The 'Glitch no more' is a little piece of electronic wizardry that removes RF signals from the ESC cable to the receiver. The aim being to reduce glitches by fitting this device between the ESC and the receiver. |

| The 'glitch no more' comes as a small piece of electronic componentry encased
in heatshrink tubing. This is soldered into your ESC cable that goes to
the receiver. The 'glitch no more' (GNM) should be soldered very close to the beginning of the rx cable that comes from the ESC, with less than half an inch of cable between the ESC and the GNM. The ESC receiver cable is particularly prone to RF frequencies coming from the ESC electronics controlling the motor and travelling to the receiver. In fact when cabling a machine the gyro wires, ESC wires and rx antenna should not be bundled together and kept separate in order to avoid glitches. Another way to remove glitches is to use PCM receivers, although this can sometimes just mask a serious glitch problem and may result in a failsafe situation (or lockout). My limited understanding of electronics is that this device basically acts very similarly to cross over units on an amplifier in that it removes certain frequency ranges from the cable but doesn't touch the desired frequencies that should be travelling on the cable. As an example, on a bass speaker you want to remove high frequencies and just leave the low ones. In this instance the 'glitch no more' is removing RF frequencies. In many respects it is acting like a ferrite ring but hopefully more effective. The only way I could devise to test this little device was to log glitches before fitting and then after fitting. The results whilst not entirely scientific in nature do provide some interesting results. Before fitting the 'glitch no more' a typical 10 minute flight would contain on average five minor glitches, infrequently I would have a major glitch (more than one servo). Post fitting the 'glitch no more' I am typically getting one glitch per flight, some flights two. Major glitches still occur but with the same infrequence as before fitting the device. In summary I therefore believe that this little electronic gadget is reducing the instances of minor glitches to the machine. However, I should note that it is not possible to verify if glitches were actually stopped by the device as I have no way of measuring the potential glitches that were filtered out by the device. |
