HiMy copter flies pretty stable except i find it hard to find a position on the throttle stick that makes the copter stay at the same height. Its kind of either going slowly up or slowly down and…Continue

James Small replied to bergsprekken's discussion log help for issue with loiter"I believe you'll find that if you select 'alt-hold' mode, you'll get the same effect. I would suggest holding on to your quad, engaging the motor, and tighten your grip, then change to the alt-hold flight mode, and I suspect…"

I have a functioning standard 3dr arducopter quad with apm1 (2560) and firmware 2.9.1b.Would it be easy to switch out the old apm to apm2.5? Can the same powerdistribution board be used so that it would be used so that its just the matter of putting the correct cables into apm2.5, like 5v from the esc etc ? Or is it more to it then that?See More
bergsprekken commented on Jani Hirvinen's blog post New GPS devices for ArduCopter/ArduPlane/ArduRover use"Hi Jani
I have bought the gps from jdrones.
Can I replace my old mtek gps that is connected to my apm1 with a cable(not soldered on) and just plug in this new one or do I have to change configuration in the firmware? (the cable seems to be the…"
Sam Giles replied to bergsprekken's discussion how to use cmos camera"I wouldnt honestly go for a CMOS len camera for this job. It isnt really good camera for some CCTV cameras for professional use. It depends on how high you want your drone to go, because you will need to think about the size of the lens you want to…"
Shyam Balasubramanian replied to bergsprekken's discussion how to use cmos camera"Hi Haidar or anyone who can echo this post,
Can you suggest me a good (low cost) camera module for a moving (RC) quadcopter. I want to be able to use Wi-Fi to transmit the images (of course, use an additional high-end board like beagleBone for…"
Luke Olson replied to bergsprekken's discussion camera disturbs the gps"The camera is probably emitting some nasty interference and it doesn't have any shielding. One thing to try might be shielding it with foil or a shielded enclosure. Another option would be move the GPS far away from the camera. Or get a…"
Tom Rearick replied to bergsprekken's discussion camera disturbs the gps"I experienced my first flyaway this weekend. I had GPS lock on my APM1 in Position Hold mode. My quadcopter has this same HK wing camera right next to the MediaTek GPS module. I ran the quadcopter up to about 400 feet confident that it would hold…"
Ervine Lin replied to bergsprekken's discussion camera disturbs the gps"Strange, I had the same problem. Never noticed it as I usually turn on the video camera AFTER getting a GPS lock.
I was wondering though, if it interferes enough to delay a lock, does it interfere during flight? I strapped on…"
Eddie Furey replied to bergsprekken's discussion camera disturbs the gps"I had a similar problem. I put the GPS out on one wing. (ArduPlane) It get's a lock much quicker when it's away from the other electronics."

bergsprekken replied to Andreas M. Antonopoulos's discussion ArduCopter 2.7.1 Released"It works now with the latest firmware. Standard 3dr frame and no changed settings. gps hold worked wonderfully, even just 2m above ground(baro only) and stayed within 1m. When i moved it around it stayed within 5 meter until it settled after a while."
bergsprekken replied to Andreas M. Antonopoulos's discussion ArduCopter 2.7.1 Released"My apm seems to lock up. I can arm it and spin the motors very carefully, but it freezes suddenly. Looks like it jumps out of armed mode because rearming with the sticks worked.
I wonder if theres an hardware fault or if the firmware reacts to low…"

John Noble replied to bergsprekken's discussion throttle response too high"You didn't mention which transmitter you have, but most newer transmitters have the possibility of a throttle curve.
My Jdrones quad wirh the 880 KV motors was the same. My new throttle curve solved this problem for me.

Fant deg her på diydrones og ser du har arducopter. Jeg prøver å kartlegge antall piloter i Norge for å skrive en artikkel om dette. Når startet du?
Også skal vi i løpet av året organisere en arducopter / uav dag og du er kanskje interessert?
