Hi, I'm also a beginner and I was wondering, will this board bind with any 2.4GHz transmitter, such as this one: ***********ebay****/itm/310678007513?ssPageName=STRK :MEWNX:IT&_trksid=p3984.m1497.l2649
Ada .. the board does not "bind" with anything .. BUT .. you need to attach the board to a PPM receiver that is properly bound to a radio (if you are using a 2.4 GHz system). You can get away with six channels ... but it's best to use an eight channel computer radio .. the TGy 9x ER9x, 9XR or the Taranis are good choices.
Hi Pete,,,,,,,,, you have a few options...... change your escs....... adjust your throttle trim up on your radio until it just starts to spin the motors......... open out your radio limits to say 125% for your throttle.,............ up your RCrates from to 1 or 1.2..........Or adjust up your pitch/roll/yaw2 (PRY) rates from 0.00 to 0.05..... then 0.10....then 0.30.......etc (these are the 2 boxes to the right of your PID boxes)
Wom Hog ... if you are using stock ESC's (not SimonK) you may have then set to "soft start" which is fine for helicopters so the start up does not stress the collective mechanism ... but is no fun to use with a multicopter as the motors take a lonngggg tiimmeeee to gather speed - which is what soft start is all about.
i am using turnigy 30 amp esc i think there are set for soft start seemed ok when i was learning to fly but seem a little slow now. i have them hard wired in to the motors , can i still check the settings of the esc while they are connected to the motors ?
Pete.......... if you have a turnigy programming card that makes the task so so easy...... I have a vid on my YTC showing how its done..... in my opinion the turnigy plush escs are as good if not more responsive than simonk flashed escs......
yes i have one will be doing on monday the quad is flying ok , just one more question i ajusted the trim on the radio so its flying with out drift in level mode, can i save them settings to the fc board , some how ?
I'm a beginner and trying to build my first quad-copter. Can someone tell me the major differences between the MTK 3329 GPS Module and a regular GPS Option? For references, I'm comparing this MultiWii PRO to *******witespyquad.gostorego****/flight-controllers/ multiwii-pro-2-0-flight-controller.html IGNORE the fact that this is MultiWii PRO 2.0, Much appreciated.
The Ublox 6M GPS units are "better" units in the sense that get sat fixes even under a roof and get more sat fixes vs the 3329. These Ublox units are also available here at HK. With MWC 2.2, the GPS are self-configured through the sketch ... same with 2.3 with some caveats. Mooch Hox posted some documents on how to configure the Ublox vs the 3329 on the Files section. Good luck on your build !
Hi guys, Could someone please tell me how I can tell if I burned out my board? I was messing around with connections when trying to setup it up in mission planner as it was not arming, and I manage to burn out the receiver, but I am not sure if I burned the mulitiwii board. I am not sure if I saw smoke from the board, i think i did near see some near the barometer, but not really sure as I was looking somewhere else. the but the receiver smells burned and it is 100% dead. The board turns on through usb and connects to mission planer just fine. It has never been flown and I am waiting for parts to finish the setup up...
Felipe....... thanks for the email. I cant reply as I cant find you email addy so if you want to resend your email complete with your email address I will reply,........... NOW...... you connected "something" wrong??? what exactly did you do IE what wires went to where ........ did you mismatch the RX wiring??..........have you got the board in a frame with motors and escs yet?.........you will need to give us a step by step, kindergarten account on what you have and what you did ....... as we are not there with you....... so its hard to know exactly what advice to give you without all the details.... when you connect to mission planner (MP) and go to STATUS you should see all your sensors working in there... if they look ok then you should be good.......
QC flying great, all GPS functions are working (i flashed my MTK with 115200 5Hz firmware). There was snowy and -1C weather today so there was not more than 7 sats on osd. Poshold was pretty fine. PIDs should be tuned for more stable flight in Horizon or Angle mode.

Duh ... I meant to write the "MWC nav" folder holding the files should be renamed to "MultiWii" .. take note the capital "W". The important libraries would be in the Arduino program "library" folder ... which should not change.
New to Multiwii.
I got Version 2.1 previously working fine (minus GPS), upgraded to 2.3, now my ESC go whacko. I can't seems to get it right. Motor only Engage at mid stick, Motor 1 and 3 kept spining almost full throttle when engage.
ESC calibration is done, looks fine on GUI, but it's not on the quad itself
Majik01. Yes. 12.51f for sydney
With altitude hold. Do you need to make sure the the quad throttle is stable first before flipping the switch?
Also i notice on the GUI the barometter is not accurately picking up altitude. Using long usb cable I lift the quad high above 2 meter. And it still reading 1 meter height. How accurate can this barometer be?
With GPS. My club flying field. Are about 300m from big power tower. Is this affecting the board sensor?
O for you mag dec. Attach an Arduino (115200 baud) blue tooth module to your copter on Serial 0 (or 1) Rx-Tx, Tx-Rx, Vcc-Vcc, Grd-Grd. Using an Android device with the EZ-GUI app (don't know if MWC 2.3 is already supported but you can test - see Mooch Hox's videos - great stuff) connect to the copter and see what is going on when you engage PH and RTH ... if your copter has a good fix or not. Power towers can affect GPS .... but one at 300m should not be problem ... try going to a different location and see if the issue persists. For your baro ... be sure it is covered with foam/sponge. When I test RTH, the copter is at a safe height with alt-hold activated - just to be sure I do not slam into the ground.
Try to do next things. First - download my sketch 2.3 from FILES tab and maybe GPS options will work for you (i have tested - they really works). If LED not blinking, download GlobalTop_GPS_Viewer_v1.8 (google it). U can set baud rate and refresh rate with this tool to ur GPS. Mine is 10Hz 115200. You can set for example 10Hz 57600 (dont forget to change in config.h baud rate 57600 in that case). Should work
Hello DM571, I cross checked the config.h, on the GPS section, the only different is I still have //#define INIT_MTK_GPS >>>>defined, now I have deactivate that. nothing major different except i2c rate which I don't use, and servo refresh rate>>> I also copy your altitute hold neutral value. from 50 to 100. I'll let update in 12 hours as it's dark now. thank you DM571 and Majik01
Great unit, with all the features you need for your MC. And the price is awsome, so normally, you cannot make a mistke on buying this unit.If you buy this features in europe, you will pay 3 times as much or more. For the HK price, you get at least the gps module ( sometimes ) but not incluiding the board, wich has a big and powerfull processor also. So another time, where HK makes our hobby affordable. This is what the MC-Flyers need to upgrade their machines.

Received the board today from HobbyKing .
After reading about all the broken Micro USB connectors on other FC like the Crius AIOP , I had a good look at the USB connector BEFORE connecting anything.
The micro USB connector is soldered to the board at the rear corners and also has 2 tabs half way down the sides.
Close inspection reveals that it does NOT have a lot of solder to hold it in place and YES it is likely to break off without some extra solder.
The side tabs do not appear to have been well soldered, my guess, surface mount automated soldering has not applied sufficient heat to get the solder flowing well around the tabs which are part of the larger metal connector shell, using a fine tipped soldering iron, care is required specially on the side near the pin headers, re soldered the metal tabs and also the rear corners of the connector, I don't think it will come off now.
Do keep in mind that is a very small connector and the cable can be used to apply sufficient leverage to rip it clean off the board, no amount of extra solder will prevent that, so be real careful not to apply sideways forces to the cable when plugged into the board.
The quality of the board, the soldering of all the other components, I can't fault it, all looks excellent.
Lots of information now in the files tab for the product at HobbyKing.
I connected the GPS to Serial 2, and the flashing LED
