Try going here  http://www.rcgroups.com/video-piloting-fpv-rpv-469/

there are multiple threads to choose from relating to fpv and on board cameras

John can you start a thread.. which is much easier to contain and get comments from the community.

Please pardon me if I've posted my question in the wrong forum.

I am a complete newbee aspiring to build my very own Tricopter. I would like to mount a camera (GoPro) on board and I suspect I would need a video transmitter and a video receiver if I want to fly FPV (i.e. see where I'm flying). Can someone please explain or point me in the right direction for step by step instructions?

Many Thanks

John

Hexcopter - power question - JP1 jumper - in or out??

Configuration -

APM 2.5

4S 4000 LiPo

3DR 915MHz radio

1200 Sonar

Ext GPS

Should the jumper be installed or not?

No camera yet but likely to be a pan/tilt affair with GoPro

thanks

mike

Question

Comment by Charlie Fox on February 10, 2013 at 5:48pm
I find with mine If I'm hovering above say 2m when I click alt hold it rises up a few meters then stops. If under 2m it drops down and lands. Its a bit of an art as it doesn't respond rapidly to throttle input. Definitely not how I expected it to act, i.e. lock at the altitude it was it when I flicked the switch. I think perhaps loiter does though as you can still manouver in loiter,

Nevermind.. Silly me, i understand ir know. You are implying my throttle stick is not on 40%-60% position?

Comment by Gonçalo Abreu on February 10, 2013 at 5:39pm

I havent quite understood what you've said. Alt hold is not supposed to keep my quad between a sensor offset?

Comment by Charlie Fox on February 10, 2013 at 5:15pm
Hi Goncalo *my keyboard doesn't have that c sorry.
That is probably normal behaviour.

In ALT hold mode the throttle becomes altitude control. So switching modes doesn't guarantee it will hold its current altitude but rather the altitude relavent to the throttle position.

Gaining or loosing altitude in the mode tends to be quite glacial but switching back out of it can be exciting ;-)
Comment by Gonçalo Abreu on February 10, 2013 at 5:09pm

Quick question for 2.9.1 users. When i toggle altitude hold using inertial navigation my quad slowly drift down(eventually touching the ground). This drift is very slow. What parameter should i look after? Is it possible vibrations are causing this?

Comment by iskess on February 10, 2013 at 2:46am

Please help. I can't get APM to see my LEA-6H. Please see the thread I started here.

I'm still not clear how to use this forum.
