APM 2.5 + Anaconda

Started by Phil Nixon 2 hours ago. 0 Replies

Thinking about buying the plane.  Has anyone been successful with A style tail and the APM mixer?   I notice it will work with a V tail.  I assume the A tail would just be reversed.Continue

Good evening,
I have just bought a apm unit with external Ublox gps unit and external power module,
This is being fitted to a Hobby King Bixler 2 Plane
I have done all the Inital setups and calibration as per instructions using the new version apm2 software
But unable to get gps lock on the screen or unit.
Can any one help with this part of setting or am I missing something out of the advanced settings
I look forward to hearing from you.

Aeropixel, to create what you want, create a custom mix in your transmitter that turns your mode channel output to low whenever one particular 2 channel 'panic button' switch is flipped and overwrites your other switch positions.  Or, I mixed two three-position switches together so that when one of the switches is in the down position, rtl is triggered regardless of the other switch's position.

Because Plane is clever.  A Plane can only be in one mode at any time.  Its a waste of RC channels to have a whole channel dedicated to a mode.  So, instead Plane supports FLTMODE_CH.  A single channel where you can set 6 different modes by configuring 2 switches correctly on your transmitter.  If you make both switches all the way down or up as RTL then that can be your "panic button".

@ Aeropixel I agree I don't know why all options aren't available on 6,7 or 8 or even 9 for that matter. What could be the reason for this I have no idea... 

Comment by Aeropixel on September 15, 2015 at 8:13am

Hello friends.
Howcome in an plane APM there isn't the option to set rc6, rc7 or rc8 as RTL mode like there is in copter?
I wanted to set RTL mode on a 2-position switch as a "panic button" instead of using it on the traditional flight mode rc5 channel, but on RC#_FUNCTION there isn't the possibility to select RTL.
Is it possible that one can't make a dedicated panic button on a plane? Is there a reason for removing RTL from the function options on plane? I tried to find a justification for that removal, but I have found nothing.
Thank you.

@Mark  you can find out about the beaglebone and the Pixhawk fire cape here.  It is now being sold and developed by Erle Robotics

How i wish i can buy 1 from 3DR. I know that 3DR is a great company. But due to lack of Financial support I'm trying to find the cheap yet quality assured APM.
Comment by Dan Marsh on May 21, 2015 at 4:42am

That's a loaded question!  My opinion is, if it works, then it's not a bad deal.  I won't say it's a good deal because you will probably NEVER get any support.  If you want the real deal, then you need to spend a little extra and purchase it from the factory, 3DR,  Although I have had some frustrations with my Pixhawk, the folks at 3DR have worked with me on resolving the issues which have really been my lack of knowledge on the product.  

Buy it from 3DR because YOU WILL need support.
