dumped MIssion Planner for APMplanner2

Posted by Dan on September 5, 2016 at 7:24am

I removed Mission Planner from my computer, I was getting several pre arm check errors with mym2.8, I installed APMplanner 2, seemed super easy to go thru the set up, it was basically the same as Mission Planner, no errors, able to arm the motors, BUT, the throttle still acts funny, stick up just slightly and from idle to what seems like high rev, (what do I know tho, this is first build), saw a guy on YouTube with same problem but no fix, almost no range from just up from idle to 100% throttle, I put props on, hit the stick up and it revved, sounded sweet, I have Cobra Motors 2217/20 950Kv, stick all the way to the top and the thing won't budge, props are on right (1045s), motors spinning correct rotation direction, I'm thinking there is a setting either in the planner or the transmitter, someone out there knows, don't keep it a secret, let a fella in on it, lol, this is a new hobby for me and I'm a quadrotard, please help, any and all advice extremely appreciated

    Im inexperienced but i think as long as tge receiver can cable up to the 2.6 there should be no issue there, i calibrated my esc's manually one by one, watched lotsa youtube and showed me step by step my throttle issue has been solved, i reset the board using the little button and uploaded the ardurover firmware, then reset and uploaded ardurover, repeating this process about a half a dozen times then resetting a final time before uploading the proper firmware seemed to work, hope this helps

    I'm real interested in the symptoms you're having with the motors going from low to high with only small stick movement. Also consider myself new to this but have been working through trying to recalibrate my ESCs. I should mention that I am building a Quad with an Ardupilot flight controller 2.6 and honestly not sure if I have a compatible Radio/Receiver using the Devo 10 radio. Welcome any comments on this.

    I was so stoked i forgot to explain the fix, basically i reset the board and uploaded "ardurover" then reset the board again and uploaded ardurover again, i was told to do this a couple times, then reset and upload the proper firmware, admittedly it didnt work the first time, i reset and uploaded ardurover probably half a dozen times abd reset before i tried the proper firmware a final time, this erases the eeprom and effectively gives the board a different "personality", then i went thru the mandatory hardware setup and the throttle acted progressively as it should instead of the on/off behavior with no progressive range that it was exhibiting when i had problems before, i have adjusted nothing since then and with a 4s 6200mah 35c lipo combined with the Cobra 2217/20 950Kv motors spinning 1045 props i was in heaven, that quad shreds the air like a dragon on steroids , kudos to Lucien Miller of Inov8ive Designs for crafting those motors, he is by far the most knowledgable person i have had the pleasure of speaking to in regards to RC motors, i admit i have had no experience with any other motors but i know when ive got gold in my hands, i hope this info gets out there and helps someone else who is having the same issue i had

    Dan: Great to hear it. What was the fix?

  • Dan September 10, 2016 at 6:27am
    Many thanks to all for the advice, i found a member with same throttle issue and a suggested fix, it worked!, have already crashed (due to showing off) and wrecked my gps module, but no worries, another on way, thought i was grounded but found out i can fly without it, so ill be sharpening my flying skills in the mean time, ill post thrilks abd spills as they happen, lol, hope every on fly's high and fast and enjoys this awesome hobby! Thanks again

    Hi, I just experienced something similar with putting a Pixhawk in a fixed wing (P-39 Warplane). Basically what was happening was the Pixhawk would take too long to boot up and arm, and as a result the ESC would go into some sort of failsafe scenario and as a result it wouldn't go into calibration mode. I read somewhere that the trick was to use an USB connection (from computer) to pre-boot and then arm the Pixhawk first, and then plug the lipo in to the ESC. Doing this allowed me to correctly calibrate the ESC. Once the ESC was correctly calibrated, I no longer needed to pre-boot and arm the Pixhawk and everything now works as expected. Hope that helps.

    Dan, Read the Wiki on telemetry logs and dataflash logs.  Screen shots wont do it.

    The real experts may be able to help, IF you can attach the log files to your post.

    Another update, the set up in mission planner went different, firmware uploaded same, set up of mandatory hardware acted different, seemed to go smoother at first, then during compass calibration mavlink kept disconnecting and the same comport was listed 3 times in the selection menu (could have been due to storms at the time which may have caused poor internet) getting a Compass 1 error but seemed to calibrate anyways (it saved some offsets and allowed me to continue) radio calibration was a pain having to reconnect repeatedly until i switched physical usb ports, then calibrated esc's individually, smooth progressive throttle wen checked individually after each was calibrated, then wen flight modes and failsafe were set i plugged motors in to output strip, and just as before, they arm and spin at idle, as soon as throttle is raised they blast up to a high speed, found a YouTube video of a fella having same issue, of course no solution in video just problem, here is link

    Any ideas?
    I'll try to do screen shots of actual board data as suggested by Harry C if i dont get it worked out,

    Thanks to all with their advice thus far, im not going to give up, its frustrating and a challenge, im up for it even if i have to get another board to compare,
    Someone out there knows how to fix this, please help

    Update, i opened my apm 2.8 (version 2.8.8 as the board reads) after watching a couple videos about cutting a trace between two pads, having some electronics assembly experience i felt confident that i could at least visually inspect the board, well, neither the I2C jumper is installed nor the mag jumper, and the layout was a little different than what I'd seen on YouTube, there are no pads in the position described on the Tube, and with the previously mentioned jumpers not installed i figured i hit another brick wall in trying to set this fc up, left a little more confused my curiosity had me checking out the board as i would have in my past work experience, my flashlight as a spotlight and a good magnifying glass were used but not necessary to see the fleck of solder crossing several vias on the back side near the analog pin's solder points, obviously overlooked during manufacturers inspection (if there even was an in spection done, it couldn't be missed) so with the fleck removed and a gentle wipedown with a cue tip and electronics cleaner im going to reset the board, uninstall apm planner2, reinstall mission planner, and start the process from scratch, i hope the board isnt fried internally somewhere and things go smoothly, ill update, of course any advice at this point will definitely be appreciated
