Before Posting an Issue

Hi All,

Before posting an issue or a problem in the ArduRover Discussion Forum, please check the wiki table of contents, review the firmware release notes in the subforum, and search that subforum for existing answers to your question. Help avoid duplicate threads by finding other members with the same issue and their solution.

When formulating your post, use a descriptive title such as "rover will not navigate to waypoints in the Auto mode" (not "HELP!" or "Problem").

Please include the following information to help diagnose your query:

  • Describe the problem you are having. What is the expected verses the observed behavior?
  • Provide hardware information such as the brand and version of your autopilot, GPS, radio, and compass, as well as any other pertinent details about your rover setup.
  • What version of the APM: ArdurRover2 firmware version are you running?
  • For navigation issues, provide your tlog and/or dataflash log. Click here for instructions on retrieving a dataflash log.

How should we handle reverse in ArduRover?

Started by Andrew Tridgell. Last reply by RoboBill 1 hour ago. 44 Replies

I'd like to add support for the rover using reverse in auto mode, so if it can get somewhere faster by going backwards it will. So I'm looking at how reverse is setup in the ArduRover code, and…Continue

This channel 5 switch "upgrade" makes me wonder what other undocumented changes were made to the DX5e line and other Spektrum models... 

Comment by Thomas J Coyle III on April 3, 2014 at 6:12pm


Channel 5 is usually the landing gear switch while the flap switch (not on the DX5e) is usually a three position switch except for the DX6i where it is a two position switch.

The channel 5 switch went from 2 position to 3. Its located in the upper left for mode 2... next to the trainer switch. 

Then I plugged the PPM channel 7 into the Aux1 of my AR610 for learning waypoints with the trainer switch when the channel 5 switch is in the center position.

As for retrofitting, I think that may take a new switch and new PCB.

That's good to hear. Maybe someone can reverse engineer the change so that existing DX5es can be retrofitted. By the way, which switch position became a three way switch?

That may convince me to consider another DX5e when I am ready to build on a new platform.  I have really liked my current one.

Comment by RoboBill on April 3, 2014 at 2:34pm

I called HobbytownUSA (they are a Spektrum authorized dealer). They told me that Spektrum made a "running change" with the DX5e. So all new ones have a 3 position for channel 5.

The Base RC I am looking at is less than 5 pounds at 1/5 scale due to simplicity as compared to my SCX-10.  An because its a crawler, having the weight properly balanced an set low will assist in the crawlers ability to get over objects or go thru objects such as logs an trenches.  Keep in mind my SCX 10 1/10 scale tips the scale at almost 9 pounds right now.  Search youtube for the things the rc crawlers are dong in the RC world.  Its amazing, just like full size if not more impressive.  Then imagine Drone Hardware able to process even close to that.  Even cooler.

A 1/5 scale chassis is HUGE:-) The biggest I have is my Traxxas E-Maxx brushless chassis and it weighs a ton in my opinion!

An that's not what I want.  Long term I want to use my Crawler in Mountain Search an Rescue.  Also taking this time of learning this setup on the ground for when I have the chance to build a Drone Plane.  Again for search an rescue.  2wd is not an option.  But Motor On Axle 4wd should be just a good since the motors are away from the electronics.

The main board was 1 inch above the motor with a plate of aluminum between.  An the GPS was about 4 inches away moved to the front.

I understand the RC design was the problem, which is why I pulled the hardware off my 1/10 scale crawler for when I can shell out the funds to build a new platform.  At 1/5 scale that should put enough distance between the motors an electronics.

@John Moore,

Your issue is why I have always used 2WD chassis except for my 4WD Traxxas E-Maxx and my 4WD Traxxas 1/16 Fiesta rally chassis which have mid-chassis mounted motors.

The 2WD Traxxas Slash chassis that I use have the motor at the far rear of the chassis and the only magnetic field that can affect the compass on that chassis is the steering servo motor. However, it is very easy to mount the compass far ahead of and above the magnetic field of that servo motor.
