Thank you Daedalus… so I figured it out… just had to arm it doyyy.
and thank you TCIII but it seems to work with no gps
Im getting some pretty wild spinning in circles on liftoff. Ive tried recalibrating the apm and the esc’s a few times… my battery is a little off center I dunno if that’s the cause… I flew it around the backyard as it did 360 after 360 seems ok other than that
im pretty sure its got the onboard compass, but from what ive read on multiple sites you don’t need the gps unless ur using waypoints, as of right now im only looking for stabilization. this page half way down says what im saying - ardupilot.co.uk/what-do-i-need.html
Even though your goal is just stabilization, the gps will help with that. The uBox GPS on the 3DR store is really nice. Have you made sure your trims on your transmitter are zeroed out? Then have you done the no wind hover, to dial in and save your trims?
Daedalus, I did order a gps, and ive been playing with the trims on the remote…while throttling up it starts to spin on my floor(FAST, clockwise rotation) It seems to help trimming a bit but then when I throttle more it starts up again, im guessing I have to find that sweet spot? Regardless of trim it seems to always rotate clockwise. Waiting on a charging battery now, def need to get some more(if I can ever get’r up)
correct wiring order on your motors to APM -im pretty sure I have this right, I have the ardupilot facing forward between the 2 front motors, the motor on the right connected to output1, the left output2, the motor in the back connected to output 4
no loose connections on the esc’s- not sure but im noticing when I start up the motors they all start at the same time, and when I cut the throttle 1 motor stops fast while the other spin until stop ( I would guess my problem is here unless its on my remote)
no reversed channels on transmitter- I don’t think so. my left stick is(updown/leftright)" throttle/rudder" my right is “elevation/aileron” and I just noticed on the display when I raise the throttle it raises the pitch not sure it that’s suppose to or not.
props mounted on the correct motor (cw vs. ccw) and none upside down- im using all pull props I think this one is ok
receiver channels connected to APM in correct order- im not 100% on this, but when I hold it and tilt it right left up down it reacts like it should so im guesing yes.
Im only using a TRI copter, on this page ( copter.ardupilot.com/wiki/connec … and-motors ) about half way down im using the tri setup on the “left”, but I could switch out 1 of the props, according to that site it would be my #1 motor I believe. I will give that a shot and report back.
I am curious which tricopter, motors, yaw servo, etc, that you have. When holding the tricopter in your hands, does the yaw motor react in the correct direction when you waggle the tail back and forth? When it spins on takeoff, can you counter the spin using opposite yaw control?
I have the same quad, same controller, same problem with the compassmot reading (139%). And yeah, it is solid as a rock in Stabilize mode. But I am not going take the chance of flying waypoints, RTL, and other advanced modes that rely heavily on GPS+compass with an iffy compass. I have read too many stories of crashes and fly-aways. I would rather spend the $17 for an external compass and get it right 1st time. Besides why would 3DR go to so much trouble to release the APM 2.6 with the external compass kit unless they were correcting an obvious design flaw. I’m going mount the mount the external compass right up on top next to my GPS and hopefully fly the full capabilites of the APM with confidence.
Point taken. However, double that for postage to Europe and add 3 weeks delivery.
I am going to try a short mission in the next day or so (when it stops raining) so I should have more data. When I did the compass mot it had the 3DR telemetry running, just powered up, and the GoPro was recording plus there is some serious Wifi in the same room. I also need to run the vibration test as well (now I have read about it. I’ll let you know how it all goes.
