I tried the APC props but in cold weather they are very brittle. The slightest touch would cause them to fracture. In Texas they should be ok. At 6000 feet and 40 degree temps they suck. I am waiting for some Graupner 11x5's.

Thanks Droider, now I feel really good. Just fooling, glad someone got theirs. Let us know what you think after the build.

Samolde: What firmware did you load to your AC? Could you post your parameters here so we can try to help you. P.S. You can also post in the Arduino thread and seek their help. Another source is on RCG. The Pirates are advancing Mega code exponentially.

Dixter: Right now I am using an Immersion 600mW 5.8gHz transmitter. You can get one here: http://www.futurehobbies.com/products/details/239/18/transmitter-&-receivers/5-8ghz-transmitter-&-receivers/600mw-transmitter-[5-8ghz] I just purchased these antennas to help boost my range...

I found this source for the DJI 450 frame. http://www.heliguy.com/Extras/Multicopter/DJI-Quadcopter-Frame/ I purchased one for less than $50 shipped to the US. I don't know how they will perform but I thought I would share incase someone else is interested. Edit: Please ignore the above...

I would start here. http://www.rcgroups.com/video-piloting-fpv-rpv-469/

Rich: I use mine for FPV. I set the GoPro to 1080p, R5 which narrows the FOV. The biggest problem is in low light, it doesn't do well. Try it you just need a cable between the GoPro Video out to your vTx and they are cheap. I do not use a separate battery for the GoPro as I have found its...

I found the problems. On the Tilt settings, I forgot to put the negative sign on the Min and had the Max set to 50. When I increased it back to the default of 1000/-1000 it was fine. Unfortunately it appears that when the roll servo locked, it stripped the gears. Unfortunately I will not be...

I finished my mods to the Coptersky GoPro 2 axis camera mount. While adjusting the servos I accidentally hit the default value button which caused the servos to bind. I immediately disconnected the servo leads to the MU. I reset the gimbal values to where they were before and now I get only the...

Too late. It ended at 5pm today.

Steve in Manual mode you are using gyros only. In ATTI mode you add the accelerometers for self leveling and yes you will have vario altitude hold. Try it you will like it. It just means that you can use the TH to set the altitude and it will hold at what ever altitude you set the stick at. I...

This is from Sidney over on RCG. Not a DJI frame, just a local customer that wanted to demonstrate his 4+Kg quad. http://www.rcgroups.com/forums/showpost.php?p=19696311&postcount=4002

I also am doing a new build. I was thinking about your comment and my test mule, an ArduCopter. On that unit I mounted the IMU and GPS/Compass on the X and Y axis in the center of the copter. It was rock solid. On my RC Carbon frame the GPS/Compass is mounted is mounted behind the center of...

Gunter, I stand corrected. Thanks for the bigger picture. I agree that the 90 degree FOV is nice and the better optics and the better low light handling are good additions. $300 is a lot right now for those features. I will wait until I destroy my current GoPro. I use it mostly for FPV anyway.

I think that is the HDMI out. At least it is on my GoPro which is not a 2.

Checked out the link. It will not work with the current GoPro and with the new GoPro2 it appears that you loose the video out jack. Therefor you are stuck with the wifi as your only option to stream video. I think that I will stick with a dedicated video Tx and a tracking receiver.

Rich, Here is a video with my WK-M hard mounted to an ArduCopter frame. When I say hard mounted I mean a piece of CF bolted to the frame and the GoPro attached with velcro and a velcro strap. The video is stabilized with iMovie, not the best, but I think that considering everything was good...

I found the build of the frame to be a non-event. I had none of the fitiment issues that many have complained about. There were two holes that did no line up but a quick pass with a file and all was good. The camera mount is another matter. RTRyder has the same mount and has been a great...

I have flown several of my machines at 6F including my MK with no problems. I did have a 330mm DIY quad with an FY90Q on it that would not arm unless I armed it inside the house and then took it out to fly. Flight times at those temps is pretty short.

No but I have a WK-S setting upstairs just waiting to be put on my 550E that is with it. Unfortunately this will probably have to be a spring 2012 project. I find my multis fly much better in the snow. :tennis:
