Drone flying to non visible point
Hi there,I encountered a problem, while flying in auto mode, with approching to point that was not set by trajectory and is not visible after downloading mission from flight controller by Mission Planner. Does anybody encountered similar problem. The situation is that in the middle flight I stopped the UAV and uploaded new mission and after changing to auto mode it starts to fly in some direction. It goes straight to some point, so I assume it's not mechanical problem. I attached the link to…

ok, maybe everyone now this and it is an obvious thing but here is what I just figured out: the "noisiness" of your 5v source to the FC will affect the number of sats your GPS will find! In about February I upgraded my copter to 6s and because 3dr doesn't carry a 6s PM I got myself an eBay version which supports up to 30v and provides V, I and 5.2v for up to 3amps. Since it was only 15usd I honestly didn't hope it would work right away, but surprisingly it worked right out of the box! Voltage and Amps readings on APM were extensively bench tested with a borrowed watt meter and my multimeter to confirm their worthiness. Everything checked out good, in fact I was very happy, I didn't even need to adjust anything in MP, I just chose 3dr power module and I had m volts amps correctly comprehended by APM. around that time I had minor crash in which I though I damaged my 3dr GPS/MAG combo, so the sats were never higher than 11 and that happened only after 5-6 minutes sitting in the open field. since it was flyable and I consistently was getting 11 sats + 1.6-1.8 hdop, I didn't bother to replace it. So here is the culmination: Last weekend I got a new 3dr gps/mag from a friend of mine and put it on the copter, again 11 sats and no more! I started experimenting with the shielding, but doesn't matter what I tried I still had 11 Sats, that's it. Finally I switched my attention to my friend's copter to see what was different... the first thing that standed out was that he runs 4s, I took his battery plugged in to my copter.... still 11 sats! ok, the only thing different among our builds left was PM. I took my old 3dr pm, soldered it onto the available leads of my PD board and hooked up a 4s batt, right away I got 13 sats and that number went to 14 in about 2 mins. that is w/o ANY shielding of GPS... I went back to my 6s ebay PM, took the gnd/vcc wires and put them through an FPV LC-filter. hooray 14sats in under a minute from cold start (due to lack of time the operations took place on different days). now I have at least 9 sats inside the garage with garage door closed, no windows and a second story on-top.
just my .02
Some help please! I have been trying to get two cannons to fire simultaneously while being stabilized by two servo driven gimbals running off pins RC10 and RC11.
When using 10 or 11 to trigger the cameras works those seem to be the only pins that drive the servos. I have tried multiple times to get RC8,7, just about everything I can
think of but I seem to be missing something. I am using channel
7 as my manual camera trigger and have set the servo out function of RC8 to "camera trigger" I am really at a loss. If anyone could point me in the right direction I would sure appreciate it.
I have another basic question:
What is the significant difference between professional autopilot systems and opensource units. IS it really worth the extra money or will opensource units be able to provide the same functionality such as blackbox, phone or tablet comms or even joystick from ground station control?
@Andre Schoonbee : I think this is a great idea :)
I am sure, such a mode like "Point of No return" will give more versatility to Arducopter code base and probably, save some folks their copters!
I have an idea/request
I believe it will be of great help if we could have a mode like "Point of No Return". The idea is that the autopilot needs to monitor the battery usage as well as the distance from home and work out the consumption of power. Then given the amount of battery power still left it should initiate return to home. This will prevent loss of the unit. TI have this as a mode will give the user the ability to select this if they are flying over difficult terrain or over water.
Hi, I am trying to pair 2 air modules of an old 3dr radios, does anyone know how to accomplish this?
@Longshot7601,
The PM Eagle files are on this webpage:PM

Does anybody have a link to the Power Module schematic? Mine isn't working and I want to know why.
Thanks in advance.
@dr0n3droid My problems started here: http://tinyurl.com/pj3yp3g
Now I think that I should have kept those clones and just transplant the voltage regulator from the old (original) PM to the new clone. Now I have none. I've sent the clones back and have refunded.
You just can't know if it's genuine or fake until it's in our hands, cuz those stores for sure don't say it's not the real thing. And the shipping costs for tiny things, gosh!
I think I'll stay here for today!
Thanks again dr0n3droid!
I keep that CC BEC around for situations like this. There is no I&V monitor, but but I can still fly.
