My KK2 arrived today. Here is a breakdown of how long it took
(Caution: items supposedly reserved when paid, but not actually reserved in some cases until it is shipped.)

Paid on Nov 28
Did not show up as paid (PayPal). Went online with support to get them to manually mark it as paid. This has happened with the last several orders.

Paid to Print Queue, estimated 3 days (includes some "3day just in time" items?)
Print Queue to Printed, estimated 2 days
Printed to Shipped, estimated 3 days
Shipped to actually left Hong Kong, 7 days.
Hong Kong to my door, 9 days
----------------------------------------------
Total, about 24 days

Tracking updates were delayed (on the 13th it finally listed the item as Accepted on the 6th) and incomplete (there are no entries for the USA cities it passed through, just a final entry where it appeared at the local post office). I guess would rather have incomplete paperwork than delayed packages though.

Not too bad for this time of the year. The biggest delays above normal were Hong Kong Post (5+ days extra) and HobbyKing (maybe 2 days extra).

I have toys!

The 4S (or any full voltage) is never applied to the board!

The ESC has a BEC (Battery Eliminator Circuit) on board which drops the full battery voltage down to 5v for the receiver and KK board.

It's up to the ESC to handle the voltage that you put on it. If they can't, and the ESC BEC burns out, then you could burn the KK board.

Just thought I'd clear the point up!

High P values with SimonK


With SimonK firmware P can be really high.
Same for I.

I just experience the same thing with my order. It took 22 days to arrive. My previous orders was 10 days average. Its the time of year I guess.

Reversed yaw gyro?


Is it possible for the yaw gyro to get reversed somehow. Thats how my quad is behaving, just like a KK 5.5 with a reversed yaw gyro. doing an overhead test everything is fine until i give it a twist then it goes crazy. any ideas?

Unless you have gone into the editor and fiddled with it, the Yaw on a Quad will not just reverse.

You have to ensure you have the correct Quad configuration selected X or + and that the motors are connected correctly as per the motor layout for that config and thet they are rotating the correct way again as per diagram for the config.

Thats it, if set up as per instructions on KK2 display no reversing of gyros required.

Only config that may require a Yaw gyro rate reverse is Tricopter and that is because of Servo and linkage variations in rotation.

maybe + instead of x
flashed mine today v 1.5 (X-config.) but didn't reconfigure it...flew in an increasing oscillation till if dropped..Luckily i was only a foot off the ground when it happened. Set it to x. with the default values and wow. this thing it 100x better than it was before on v 1.2. self level is really solid now.

He meant to add "...except to the low voltage detection circuit which does not even come with a connector attached. You have to solder your own."

Was it oscillating at 70+ with the stock ESC firmware?

What was the final value you used for P on the flashed ESC's?

Arduino on the KK2


Hey all.

A few of you will find this interesting.

I have been working on some code to make it possible to use the Arduino IDE with the KK2.

It includes a working LCD library and examples.

Article here.

and thread if you want to discuss it.

Marc.
