    colin guinn booted from DJI

    Is there a list of which US dealers are unaffected? Hopefully AMP, as they're the only one I've heard who consistently gives good service to customers.

    highest posible windspeed to fly?

    Will DJI systems initialize on a boat? That's something we have had problems with on APM. The gyros need to be stable to calibrate. There was one guy I know trying to do work like this, and his only solution was to boot up the system on the shore, and then keep it alive with hot swap...

    Colin Guinn Injuction Video

    +1! So whatever happened to Cineron? I really haven't heard much about it other than these intro videos. Did they fall by the wayside with the multirotor and AlexMos revolution? Or are they quietly out there shooting Hollywood stuff and we just never hear about them? Is Colin still involved...

    Colin Guinn Injuction Video

    My guess is that they cannot sell to any previous DJI dealers. Colin Guinn probably had exclusive rights for marketing and distribution in the US, and would have had a non-compete clause which would prevent direct sales from DJI HK to the dealer network he developed. DJI HK can probably go...

    colin guinn booted from DJI

    Did this whole problem start because of the SpaceX incident? http://www.dvinfo.net/forum/flying-cameras/517675-rocket-test.html

    highest posible windspeed to fly?

    Yeah, it's possible, but tricky. This is actually sort of a worst case condition video. A really crappy quad, flight controller not completely tuned in. Not just high winds, but in an area with very high turbulence. A conventional RC heli would have much less problems in these conditions...

    colin guinn booted from DJI

    Holy cow, have you guys seen this? Pretty big news! Colin Guinn attains an injunction against DJI HK. All US sales halted. http://www.youtube.com/watch?v=kDgSNApm4go

    lets see some clean wiring jobs

    IMO, anybody using ~24 wires to join the Rx to the Flight Controller automatically fails this test. :highly_amused: Just kidding but uh... Does DJI not do PPM Sum?

    12s compatible flight controllers

    I've been doing this for 2 years on APM. You just need about $0.15 in resistors, and a soldering iron. For 12S voltage sensing you need an 11 or 12:1 voltage divider. So, a 10kohm and 1kohm resistor will do you. Amperage is trickier, but do-able. I don't generally bother with amperage...

    Pixhawk the new flight controller from 3DR

    Well, you can flip from Auto mode to Loiter (or Stab, or whatever) and then fly around, and then put it back in Auto mode. I believe it should resume the auto mission from where it left off, but I'm not positive as I've never tested that. Marco's new mode is interesting, but personally I...

    Pixhawk the new flight controller from 3DR

    No, what I'm working on is not anywhere near ready for public consumption yet. In fact, it's stalled for a bit as I smashed that quad the last day. Not *really* caused by a code fault, more just dumb-thumbs. But yeah, this is a little ways off yet. Hopefully will come out with a 3.2 release.

    Pixhawk the new flight controller from 3DR

    Ok, so that sounds exactly like the situation I'm talking about and working on to fix. I've got a crappy video here. Unfortunately, it's winter up here and flying opportunities are limited. Yes. You would just put a Loiter after every waypoint, which will make it stop at the waypoint and...

    3DR APM 2.5+ max current through power module???

    Hey Bart, sorry I haven't been around here lately. I actually don't use the current sensor on any large machines. I use it on my 450 quad, and I'd use it on my 450 heli, maybe my 500 heli, but that's about it. I never used it on an Octo or my large Heli. The reason being... well, if you look...

    Pixhawk the new flight controller from 3DR

    Hi guys, I'm one of the developers, and am quite interested in what you're talking about with "smoothness" and performance with heavier machines. I'd be interested in seeing any kinda of info, descriptions, and logs that you can give me. I rebuilt the Acro mode so that it actually works well...

    APM v2.5.2 "Bad Gyro Health" message

    It's extremely unlikely that the firmware is what is actually causing the regulator failure. Nobody has come up with any kind of plausible mechanism for to happen. It is basically a consensus that the regulators fail for some unknown reason, and it's just that the new firmware (running the SPI...

    APM vs the big boys (heavy lift octo's)

    Ok, first, my name is not Bob. APM is still the default system. Pixhawk only because commercially available like last week, and they're still filling pre-orders. PX4 is basically the predecessor of the Pixhawk. It's mostly the same hardware, but is on a compact double-stacked board. The...

    APM vs the big boys (heavy lift octo's)

    Well, if you're comparing the APM to another system that doesn't even offer telemetry and data logging... does it matter if it doesn't work on an APM Octo ? Regardless, Pixhawk is here now, so this will become a non-issue. I'll show you some videos I shot. This is with my own Octocopter. 2...

    external compass from 3dr showing erratic readings

    I'm thinking the orientation is set up wrong. That's an older compass, and was actually intended for APM1, which used a different orientation than the APM2. Did you cut the jumper? http://copter.ardupilot.com/wiki/common-external-magnetometer-for-improved-performance/

    APM vs the big boys (heavy lift octo's)

    IMO, the reason why you don't see APM discussed here much, is not because of performance or anything like that. It's just because it's too inexpensive. No offence intended, but this is very much a "you get what you pay for" forum. It's just the prevailing perception here. It's often true...
