Does anyone know how to setup failsafe on the ezUHF system?Documentation on the web states the data below but that looks like it will just move to the throttle 0 position which is not low…Continue

Does anybody know why I cant use a Geo Fence when I'm trying to plan a mission on Mission Planner?And when I say I cant, I mean its not selectable when I right click. Thanks.Continue

hi,Is it possible to connect my ezuhf diversity receiver to the apm 2.6 using only one servo cable(ppm i believe it is called). This will be great if it is do-able.Continue

hi,I recently bought a frsky taranis. Am i supposed to use the frsky firmware on their website or should i goto the opentx website and get the version there(which is much newer). ThanksDamoContinue
so we were running some flights over some farmland the other day and a couple things came up..
Thanks for your help
BustamyTool... the pins do not need to be in place.
There are two flavors of power modules... the kind that provides 5v to the APM along with the voltage and current readings... and the kind of power module that only reads the voltage and current but does not have a BEC and therefore does not send 5v to the APM. It sounds like you have the kind that only reads voltage and current but does not have the BEC in it.
I have no idea why it would do that. You might send Jeff (on that tutorial) a PM and ask him. He has helped me LOADS!!!!
That was the ticket! Thanks On a related note, you are required to use the "relay" triggering method for this application. However , each time I connect to the APM, that specific param reverts back to "servo". I have not noticed this with any other param, and don't get why it would always revert back.
Sean, check out this link for a GREAT DIY hack that will help you on your way.
The tutorial shows how to use APM to do this, but I bet you could use an AUX on the Turnigy with the right PWM to accomplish the same thing. You might even be able to mix two channels on the Turnigy to simultaneously trigger both cameras, but using APM to do it is much easier IMHO.
I am a bit new to it, but I am triggering a couple cannon cameras with the CHDK USB connected to the with a turnigy Rx switch. All i am looking for is a high PWM signal. It seems like it shouldn't be this hard. I think I just have some servo or PWM limits out of wack.
I guess you're triggering "cameras" not "cannons"! In any case, it may be because the update rate on the pins on the back of the APM are running at 490hz while RC10 and 11 only run at 50hz. It's likely the servo or whatever that is attached to the pins that can't handle the high update rate.
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.
