jumpy motors with props attached

Started Sep 11, 2012 0 Replies

I know this is a regularly discussed topic, but I just switched out my NTM 28-30 750 kV motors for NTM 28-36 750 kV motors and several of the motors are jittering. I am flying a previously known…Continue

Hey gang,I recently upgraded to the APM2.0 for my aerial video platform (F550 clone from Hobbyking). I followed all instructions and brushed up on my PID tuning skills, but on my maiden flight the…Continue

GPS on dji F550 frame

I purchased a f550 frame and am currently awaiting my APM2.0 purple setup with integrated GPS. My question: will I be able to mount the board in the middle of the two plates or will I not get a GPS…Continue

jumpy motors with props attached

I know this is a regularly discussed topic, but I just switched out my NTM 28-30 750 kV motors for NTM 28-36 750 kV motors and several of the motors are jittering. I am flying a previously known configuration with PID settings etc. I have calibrated ESC's and all of them are set up with no brake, no governor, and low timing. Without props I can spin up the motors and they all seem to operate correctly, but when I put the props on (10 x 4.7) the motors will randomly twitch at low RPM and finally…See More

Will Kruger replied to Victor Iliescu's discussion After a few months of flying, i've come to the conclusion that i have no idea how to tune this thing
"Victor (and APM community), I only bought the APM 2.0 last month, but I feel like I share the same frustration! I guess i'm off to an okay start, but I really need to get this thing dialed in so I can take my AP/video to the next level. I…"

":) glad to see you have sorted it out. Version 2.7 is available, if you want to upload it via mission planner, update mission planner to actual 1.2 version and you have the 2.7 firmware available. Always perform a erase and reset before updating,…"

"I think this case is closed! After a lot of self inflicted hair loss I figured it out.  All my troubleshooting lead to the direction Rui went with his most recent suggestion. I deleted some extraneous models in my DX7 and started from scratch.…"

Rui Manuel Cravo Marques replied to Will Kruger's discussion F550 hexacopter MAJOR set back!
"That is indeed strange, I mention the motor sound because I have a 1800gr hexa with the same approx specs than yours (xaircraft diy hexa frame vs your dji) and sunnysky 2212 980kv motors with 3s battery and mine lifts with a less rpm noise (using…"

Will Kruger replied to Will Kruger's discussion F550 hexacopter MAJOR set back!
"okay so I checked and double checked the rotation and prop orientation. everything is good. What is strange is that when I bring up the motors to just where they start to spin the perpendicular left motor seems to start to race...when I yaw right it…"

Will Kruger replied to Will Kruger's discussion F550 hexacopter MAJOR set back!
"That is definitely a rookie move that I didn't even think of! Sometimes it's something so obvious like that... So to refresh my memory - clockwise rotating props are 1047R and counter clockwise are 1047? Motor layout and rotation seems to…"

Rui Manuel Cravo Marques replied to Will Kruger's discussion F550 hexacopter MAJOR set back!
"Hi will, I'm sorry to pound this issue again, but your hexa seems to be achieving a too high rotation before taking off, wich usually is a symptom of propellers mounted wrong way. Make sure all your propellers have the lettering (with size and…"

"brake is off...."
Jul 24, 2012
Rui Manuel Cravo Marques replied to Will Kruger's discussion F550 hexacopter MAJOR set back!
"Also, have you checked if the ESCs have a brake feature and if some of them have it on ? That could also make strange behaviours since when they slow down some will loose rpm faster than the others."

"Full battery 4s with 5000 mAh it hovers right at 1/2 stick...no more than 3/4 stick when battery gets down to 13.8 (ish) V. I always land before the voltage drops below 13.4. I'm not positive on total weight all up, but I'm guessing…"

James replied to Will Kruger's discussion F550 hexacopter MAJOR set back!
"how much weight are you carrying, whats the total flying weight? how much throttle does it need to hover? a bad esc or a bad connection somewhere might be able to destabilize it this way, how about testing each motor and esc seperately to make sure…"

"Just confirmed everything is okay on the radio. No mixes and Tx is in ACRO mode...everything is definitely in the last known good configuration. I feel confident that the boards are okay because it seems like they're both acting up the same way…"

"No bumps with the ground since the last successful flight & i'm not sure how the motors could be misaligned b/c the frame will not really allow that. The really frustrating (but also comforting) part is that I disconnected the APM 2 and…"

"Hi Will, Have you confirmed your radio is in ACRO mode and no mixes are active ? (do not use HELI mode)"
