I finally got my 250-sized quad ready to fly. \u00a0 \u00a0The last 2 things I did were to add a LMOA (Lost Model Alarm<\/a>) and configure failsafe in Cleanflight. \u00a0Luck was on my side yesterday as Murphy’s Law kicked in when I took the quad out for it’s first full flight test in a nearby field. \u00a0 Admittedly, I still consider myself a noob with much to learn… \u00a0That said, I was flying FPV and decided to push the limit on distance (oddly only about 750 meters). \u00a0 The radio lost control of the quad, which was immediately followed by my FPV video start to jitter, and then it went to fuzz. \u00a0This\u00a0all occurred in about\u00a03 seconds.<\/p>\n

The picture below shows about how far away the quad was (look to the powerline to the right). \u00a0\u00a0\u00a0I found myself in a bit of a panic and pulled the goggles off so I could get a sight line of the quad as it fell out of the sky way off in the distance. \u00a0What happened next was rewarding. \u00a0Fist off, the failsafe worked. \u00a0The quad took control and engaged failsafe throttle (about 1350) and slowly fell out of the sky – so it did not come crashing down. \u00a0This allowed me to get a good idea as to where I would find it. \u00a0 After trudging through 2 foot high wheat across this vast field, I then engaged my lost model alarm on the TX. \u00a0After flipping the switch on \/ off every 20 feet or so, I finally heard the faint noise of the buzzer.. Whew! \u00a0Found it! \u00a0 These two safety features saved me hundreds of dollars. \u00a0I doubt I would have found the quad without them. \u00a0Let alone in one piece.<\/p>\n

Moral of the story – if you don’t have both\u00a0of these enabled on my multicopter, \u00a0get them! \u00a0 They are easy to setup and configure. \u00a0Failsafe takes all of a few minutes to configure and test, and you can buy (link <\/a>& link<\/a>) or build your own\u00a0LOMA <\/a>for a few bucks Side note – I find it odd that my quad lost TX so close as these things should be able to go for a few KM’s. \u00a0In hindsight I figure it was likely a combination of the FPV and motor current draw on the battery (1500mAh), as well as those power lines causing some sort of interference.<\/p>\n
