Multicopter drive components

Started Jan 20, 2013 0 Replies

Had a fly-away today so need to build another 'crash multicopter' for general aggressive flying and practice. The fly-away, once I found it about half a mile away from launch was pretty much…Continue

Kieran replied to Euan Ramsay's discussion TM1000 & APM power module = no flight pack Voltage data to DX8?
"I connect the TM1000 voltage connector to my flight pack directly. I don't think there is any battery pack voltage at the APM."

Kieran replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released
"Great to see there is a way to do this :-) I have been seeing large compass offsets in my logs so I tried a few things. One experiment was to remove the APM from the copter completely and just have it sitting on my desk with no nearby lumps of…"

Kieran replied to Jérôme Walrave's discussion Minim OSD fried ? no OSD data...
"What happens when you disconnect the camera? Do you see the overlay then?"

Kieran replied to Al Lowrie's discussion New APM2.5 suddenly quit - no function or Mavlink - Need troubleshooting help
"Looks like you have a broken board then going by the missing dataflash and compass errors. Perhaps someone more familiar with how the hardware is connected up may be able to know of any possible fixes, but without dataflash being detected it's…"

Kieran replied to Al Lowrie's discussion New APM2.5 suddenly quit - no function or Mavlink - Need troubleshooting help
"If you can get to the terminal screen to do the reset and you can update the firmware and it all responds, then maybe you don't have too much if any damage to the board. I found that the APM can be very picky about being connected via a USB…"

Kieran replied to Al Lowrie's discussion New APM2.5 suddenly quit - no function or Mavlink - Need troubleshooting help
"If you took the 5v output from the step down reg and used that to power the PAN servo directly you might have some better luck, I.e. don't power the pan servo from the APM via the RX. The APM can provide power for the RX but I think it's a…"

Kieran replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released
"I tried re-enabling a few more logs today and the copter worked fine in Land mode - so the 'lurches' were not soley down to the log messages taking up too much of the run loop time. Perhaps it was the PPM encoder or the PPM encoder in…"

Kieran replied to Al Lowrie's discussion New APM2.5 suddenly quit - no function or Mavlink - Need troubleshooting help
"Sounds like your pan servo drew more than 0.5A and blew the fuse on the APM."

Kieran replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released
"Mu-metal might help. Anyone know of reasonably priced Mu-Metal sheets that are available in the UK? Only stuff I can find on eBay is 50 pounds for a meter long strip which is a bit more than I need. Hanger10 will not ship to me."

Kieran replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released
"I flew three packs this afternoon and the copter behaved itself very well. Stabilise, alt-hold, RTL, Land, Loiter, battery failsafe and throttle failsafe all worked great :-)"
Feb 24, 2013
Kieran replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released
"I flashed the PPM with the latest firmware and turned down logging, switching off MOTORS, RAW and ITERM. I reset the compass offsets to 0 and re-tested. Land works perfectly now, both when requested as well as forced due to low battery.…"

Kieran replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released
"Thank you Randy and Leonard for taking the time to look at this for me. I am using a Spektrum DX8 with an OrangeRX 9 channel RX, so perhaps that does have some glitches. I had a further test flight this afternoon and flew until the copter landed…"

Kieran replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released
"I have been trying out various flight modes on my 3DR Hexa, 880kv motors, 3S battery, APM 2.5 w2.9.1 firmware and more or less default tuning. It flies very well in Stabilize and Alt-Hold is rock steady with very little climb or descent while…"

Kieran replied to Thomas Gregg's discussion MinimOSD won't show text when camera is plugged in, fine without
"It turns out that I had already been using 2.1.5. After experimenting a bit the OSD works fine with the video output from my camcorder, but not with the output of the camera I was planning on using in the hexacopter. So looks like I need to change…"

Kieran replied to Thomas Gregg's discussion MinimOSD won't show text when camera is plugged in, fine without
"Great, thanks. I think I am only using version 2.1.3 so I'll grab 2.1.5 and try it out."

Kieran replied to Thomas Gregg's discussion MinimOSD won't show text when camera is plugged in, fine without
"I am glad I am not the only person with this issue :-) I've tried NTSC and PAL to see if that makes a difference and it doesn't. I am going to try a different video source to see if that changes anything - but I need to make up another…"
