A week of Arducopter misery
Started this discussion. Last reply by Gustav Kuhn Sep 22, 2011. 28 Replies 0 Likes
After a week spent working on my Arducopter 2, I have still failed to get it airborne and I've broken two props already. In the interests of other people avoiding the misery I've had to go through,…Continue

This is my second issue with my AC2. My previous post 'GPS prevents motors arming' describes the history of my AC setup problems.This issue relates to the flight data feedback received in APM…Continue
GPS prevents motor arming/booting

Hi forum, I'm a relative newbie in that although I bought my AC about 6 months back, I've only now started working on it.Problem: with GPS connected my AC2 won't arm the motors/boot properly. As soon…Continue

John Stuart commented on Chris Anderson's blog post Where drones sit on the "hype curve""As an early adopter and gross mis-spender on sUAS technology, I am already firmly in the Trough of Disillusionment. When monitoring the forums, I can immediately sniff out a new, overhyped product that is poorly-tested, under-supported and very…"
John Stuart commented on Todd Hill's blog post Attack of the Clones!"I agree, I just don't get the logic that you can create drones out of the cheapest components possible. Its an aircraft after all, it goes against all the logic of aircraft engineering, which requires multiple redundancy.
It worries me that…"
John Stuart commented on Adam AKAV8R's blog post "Explorer" New twin from the makers of the Maja"Coroplast - are you sure? It degrades and disintegrates from UV exposure, its not a robust material at all."
John Stuart commented on Matthew Schroyer's blog post Journalism Drone "Journo Drone 2" takes flight"Well done, kudo's for hanging in there. My AXN Floater has a skew nose from all the bad launches."
John Stuart commented on Jani Hirvinen's blog post jDrones News: MultiMount, Multi-Arm motormount for multicopters"The rubber cushions are a brilliant idea, for those of us striving for stable video. I'll be ordering a few of these to see if I can adapt them for my MK frames. Well done!
Any plans for a vibration-reducing load rail setup? Something like the…"
John Stuart commented on CyborgCNC's blog post New Heavy Lift QuadCopter Frame from HH"Its just a quad and its in a '+' configuration? Still, price is unbelievable."
John Stuart commented on Gareth Rens's blog post APM2 conversion to Naza"@ Gareth have you heard of the DJI GPS glitch in the Southern Hemisphere? The guys in Oz have complained that their DJI M kits don't navigate at all (you can find the thread on rcgroups). If I'm not mistaken, the same applies here.
On the…"
John Stuart commented on Azam Shahani's blog post Impressive new camera gimbal"The thing with expense when it comes to aerial video by UAV is that there is a tension between cost and expendability. Like it or not this technology is still quite risky (as with all aviation) so you can't compare the cost & performance of…"
John Stuart commented on Graham Dyer's group South African DIY Drones User Group"John in CT - Somerset West end. Have a few ACs, a few MKs, an FY91, a Hoverfly and some foamies. A bit of an addict I guess!"
John Stuart replied to James Dinh's discussion What's the best prop and prop size for hexa with 880kv motors?"Larger props are also heavier and make your motors work harder, ie there is also an efficiency trade-off. But if you can afford mega-bucks for carbon fibre props, this won't be a problem."
John Stuart commented on Mike Thorlin's blog post Skywalker Flight #4 - Resounding success...mostly"Hi Mike, no what I meant was the APM-based failsafe. This is independent of the receiver failsafe, if the APM ceases to receive transmitter input it activates either RTL or 'continue with mission', depending on how you configure it. You…"
John Stuart commented on Mike Thorlin's blog post Skywalker Flight #4 - Resounding success...mostly"Just a question - did you consider enabling a RTL failsafe and in the event of the mission going awry, just switch off the transmitter to activate RTL?"
John Stuart commented on AirviewLive's blog post Shielded hexacopter is safer than the rest"Are you sure that the safety improvement factor justifies the decrease in efficiency? If you are concerned about flying near people then the overall weight & size of your hexa will still constitute a serious risk if it impacts a person, with or…"
John Stuart commented on John Arne Birkeland's blog post Confessions of a gadget addict..."I have a similar collection. BTW where are your MK boards and BL controlllers? Every collection needs one of their stacks."
John Stuart replied to herve pellarin's discussion arducopter 2.5.4 outstanding loiter mode as good as wkm"Why be scared? You can just flick the switch back to stabilize if anything looks like its not working. I've tested RTL and loiter many times and not been happy with what happened immediately, or soon thereafter, and just went back to stabilise…"
Profile Information
- About Me:
- I'm just starting out in UAVs, aerial and video photography and FPV flying. I am a Hang IV equivalent rated hang glider pilot in my country and so I have a keen sense of flying by the seat of the pants, especially landing with no go-around power! Being a HG pilot also teaches you a lot about micromet, which I'm sure is useful in the UAV area too.
- Tell us a bit about your UAV interest
- I am primarily interested in UAV technology as a platform for aerial photo and videography. My country is blessed with huge wide open spaces, with little air traffic, and so ample opportunity to practice this technology safely.
