Hi All, Does anyone know where to source a four pin plug that will go into the mag socket on this board. I have had some issues with the internal mag on a small quad being to close the internal electronics. I have a mag with different plug on the end from an APM 2.0 that should work / be easy enough to swap plugs. Thanks in advance

That connector is called DF13 and you can buy it from a specialized website like digikey i boought it there with also some pre-crimped cable.
 Ossy Flop 9 points
Hi Matteo, I'm guessing for the IC2 port this should be a DF13-4S-1.25C With the 4S relating to the number of wires and the 1.25C relating to the separation centres of the pins in mm? I couldn't seem to find DF13's at any other separation, although it seems odd to specify the pin distance if there is only one choice?
 Matteo 17 points
Yes, the DF13-4S-1.25C is exactly what you need :) "4s" means 4 contacts, 1.25 is the sdandard distance and the only one that exist

Hey Guys, iv been looking everywhere on the net. is there a way to setup a switch to slow down/smooth out the yaw control for doing smooth video. i will be using a 2 axis gimbal and want to use the copters yaw to obviously control the yaw but surely there is a way to make it smoother and super easy to use.
 EricBR 374 points
You can use dual rates and exponential on your transmitter or lower the yaw rate in Mission planner

Hi, is it alright to have my usb connected aswell as lipo supplying voltage the the board? ta Rob
 EricBR 374 points
I'm 100% sure it's ok to use Usb and lipo at the same time if the jumper is off. Never tested with the jumper on the board
 Robwuk 1 points
The jumper is off as im supplying the 5volts using a ubec and its connected to my receiver.
 EricBR 374 points
Hmm. I use power module witch is kinda a ubec and it work with Usb. I think would be safe if your receiver is connected only by the signal wires, the white ones, to the board
 mohag 50 points
There is a diode that prevents current from flowing from the USB back to the outputs. As long as the BECs on the output is less than about 5.5V it is safe.

I can hover and loiter but impossible to follow mission, the quad stay in loiter mode, does not go to next waypoint. Even RTL do not work. I dont know why ??
 mohag 50 points
The forms over at DIY Drones might be the most useful? The logs can also give insights into why it acts a certain way...

Is this the forum for this issue? I have problems with my HKPilot Mega locking up and not responding to the transmitter resulting in a crash. I'm using a Turnigy 9X & receiver and installed the APMplanner2 on Linux to configure the HKPilot Y6 firmware on a scorpion Y650 with Multistar 30A ESC and Propdrive 2830 motors. All calibration has been done and range checks on the transmitter are fine. When I run it on the ground to check control it looks fine but as soon as I take off and gain 6-8ft altitude for a few minutes, It locks up and crashes. after the crash the transmitter is not able to do anything until the battery is disconnected and reconnected. I'm out of ideas at this point.

i have a similar problem, i havent foud the reson yet but if you switch mode and switch back again the engine stops... it may be caused by lack of current to the board.
 kbarrow 1 points
I suspected that also, but I'm using the power module and fresh batteries. Everything checked out good concerning power. I'm thinking it's the Pilot SW or the BEC SW. I'm buying the flash cable to upgrade the BEC firmware and checking with the APMPlanner guys about the HK Pilot firmware...

At first, the touch and fell is good. Nice solder quality. After fitting the right software, I come back with a review of the flight characteristics. First I have to fill it up with arducopter software. People say, that flies better than MWii, but i´ll see and come back with comments.

just the same as apm2.5 but missis a few pinheaders i instaled this in a case from the original manufacturer works great and cheap the soldering could be done a bit better but for the money who cares i did not yet have found problems with this yet

The board come with Arducopter 2.8 pre-loaded. I updated it to 3.0rc4. Everything seems to work normally. I've tested every sensor and they seem ok. Soldering is pretty good as well as the black color :) I will test it on my quad and report but the boards seems to be a great value. Too bad that HK don't ship it with some additional cables like the MegapirateNG board. I hope that they release APM case for it as well as the telemetry cable and some additional plugs and wires.

Initial impressions and testing are good. It takes a while to setup all correctly and make sure everything is working perfectly. Put it in my deadcat 450 didn't touch any settings took it up in stabilise mode and it flew nice and level. A bit pitch touchy but nothing settings can't fix (its the nature of the dead cat IMO). Also purchased the LEA 6 Ublox gps, will be posting follow up comments when more testing has been done. So far great value.

I installed this board on my dead cat quadcopter and so far it's worked like a charm! I haven't used it with the GPS yet but when I do I can post a comment to update everyone. Setup: Deadcat frame, Multistar 30A 2-4S Brushless ESC, no-name 1000kv 2212 motors and 1045 props. Only a couple of things could make it better- a side entry version like 3DR offers would work better for multicopters and protective plastic case like 3DR offers should be included to protect the investment
