Unexpected motor glitches (speed up) with Tri Hex and Octo APM 2 & APM 2.5 using 2.73

Started this discussion. Last reply by RedPalm Dec 16, 2012. 78 Replies

It seems since going to 2.7 and up to 2.73 I am having uncontrollable glitches with the motors. I think I have isolated everything, no bullet connectors, checked the amperage draw of the 880 motors…Continue

Magnetometer won't stay calibrated with 2.7, worked fine with 2.6

Started this discussion. Last reply by Don Fiedler Jul 31, 2012. 3 Replies

My heading in Mission Planner does not shoe the correct headings, consequently my loiter is all over the sky. I have done the live calibration several times. It seems about 90 degrees off after the…Continue

Update GPS on APM 2

Started this discussion. Last reply by Jake Stew Jul 30, 2012. 1 Reply

I know how to update the GPS externally mounted with the FTDI cable, but how do you do it when it is mounted on the APM 2 board, or can it be done......Don

Cannot get position to set up, loiter is next

I am trying to get my hexacopter with the heavy motors & esc. to work, if there is any wind at all, it wants to drift downwind in "position" mode. "Stabilize" is fine. I have the APM1 and am…Continue

"cirilo, Another question, are you using the pots for the roll and pitch, with those servos, you need both pots as there are no pots in those servos. You don't need their pots, but for the pitch it is good as you have many more options with the…"

"It sounds like your tilt is reversed, go into MP and change the reverse box, check or uncheck, see what that does. Roll, is the servo using the internal pot, or do you have an external pot........ I assume you are using the APM 2 or 2.5,…"

"I have that same setup, it will work, I am using it with the APM 2.0 and 2.5. I had a problem with my roll oscillating, the pot I got from Quadrocopter was bad, I replaced with just a Radio Shack 5K pot, you do not need a 360 pot in the roll…"

"I am using the Cinestar with the APM 2.0 and have tried the 2.5 as well, connecting the servos to 10 & 11 on the APM. The pitch works wonderful, however the roll just wants to oscillate, bad enough that I cannot fly with it. It oscillates about…"

"A similar scare happened to me about a month ago with 2.81 on a hex. It was flying fair in loiter, seemed to want to search for the wrong heading. I switched to land in stabilize (I think), and for some reason I found it hard to set it down, then…"

Don Fiedler replied to Randy's discussion ArduCopter 2.9 released
"My throttle was at about 25% to hover. I changed my TX curve, now it hovers around center stick, but engaging loiter it drops, so I increase throttle on my TX, it then holds at about 75% stick. Then when I go back to stabilize it shoots up unless I…"

Don Fiedler replied to Randy's discussion ArduCopter 2.9 released
"Ok, I got that figured out, when in stabilize to hover my Futaba throttle/collective is about 25%, as soon as I engage loiter, it drops, so I move my throttle to the mid-point and it works fine. Do I adjust my curve on my radio, or something else.…"

Don Fiedler replied to Randy's discussion ArduCopter 2.9 released
"I have a similar problem since 2.9. No problems with 2.81. No sonar, stabilize works fine, however once in loiter, if I climb, it wants to keep climbing, if I command a down, even full down it takes about a second to start down, then it comes down…"

"I read somewhere that the bottom ones need to be a little larger to overcome the prop wash from the top ones. Have you experimented with different sizes."

"UPDATE:  After getting similar symptoms when I replaced the APM2 with KK2 and also during a bench-test without any FC (just a 1-to-4 servo wiring), I am convinced that my problem isn't the APM2.I suspect it is ESC/motor-overheating.…"
