I'll bet there's a battery backup for the sat data or some other method. They would not have gone this far to forget to save the sat data somewhere. It's just too obvious of a thing to do for them to overlook. It takes 15 minutes or so of seeing the same satellite to receive all the data...

That sounds great Ken. It looks like a winner. I had seen a mention that there is a 115 foot height limit for alt hold. Is that true?

Warthox, I think you could have done it much faster with a flip in between each run. :) Congratulations koka!

He sells plate mounts that fit the clamps.

Glad you're OK Ken. And it's good that you were smart enough to think ahead and charge batteries. Where I am at, we were lucky enough to miss all the wind and rain. The internet even stayed up and that tends to go out if you look at the antenna wrong. All the hotels near me were full of...

Rusty in the US sells something similar. http://www.shop.aglhobbiesllc.com/Frame-Spare-Parts/Delrin-Clamping-Block.html I stuffed the end of my tubes with polymorph plastic to strengthen the clamping area.

You should be able to see proper I2C communication when the BL-Ctrls are powered. There is a test procedure in the .de wiki for the BL-Ctrls, AFAIR.

I know of a large 'brick and mortar' auction company that charges a buyers premium of 15% and a sellers commission of 10%. I think the others are similar. <shrug>

'Might' is the keyword. FC .78f is generally considered to be stable. I think .80 'may' have had some problems. It's hard to really pin down because there is so much to go wrong with these things that it's not always easy to blame firmware. You should probably start a new thread to get others...

Generally speaking the MKTool version has to match the firmware you will be using. If you want the latest features then use the latest MKTool and upload the new firmware to the boards. Older versions could be more stable but that's a whole new debate.

I have all the schematics. The problem is matching the schematic to the board without silkscreening or a graphic that shows placement. Something like the pic below would be helpful. MK may have put one out but darn if I can find it on the wiki.

As I understand it, most of the caps on the BL-Ctrls are for filtering power fluctuations. I can't find any parts diagram for these new boards to determine exactly what part number is in each location. I've had my doubts about the manufacturing process with these for a year. I don't think I...

I don't have any of those ESCs to check. Do you have a macro photo of the bad board and a good board? Is it possible that you sent reverse polarity into the boards?

I've been thinking about this off and on for the last 18 months. I even bought a few small chutes to test with. Various methods have been attempted by others with varying degrees of success. My idea is to use a spring loaded carbon shaft with a chute connected to the end. A servo would release...

Have you looked at the sensor readings in the MKTools scope?

I have a set of ExceedRC Proton 30A and gut feeling is that they seem different than Plush or SS. Here's my understanding of the underlying issue. I'm sure someone else can explain it better. Part of the problem is the way ESCs currently work. When the flight controller sends a message to...

If you flip the cap over, are the metal pads still on it? Any chance you can take a macro photo of the cap and failed joint.

It's actually not that hard with the right tools. (see pic) But you are right. MK should solder on at least some of the components. I think they do it so if the board is bad, they can blame it on the builder. ;) Can you take a pic of the missing part on yours? I've been seeing a few parts...

That's exactly how it should look.
