Title: MinimOSD - APM - Servo Power System
Post by: parichya.gautam on February 26, 2015, 05:02:36 AM
http://imagizer.imageshack.us/.../skywalkerwithflapse.jpg (http://imagizer.imageshack.us/.../skywalkerwithflapse.jpg)

followed this and did it.

NOW, when the OSD is connected, there is no video feed and just one RED LED lights up.

I guess there is something more to do ? Flashing ? I have the USBASP cable , please , how do i do it with that ?

Or do i have to get the FTDI thingy ? if so , from where ?

SO AS IT TURNS OUT ... the OSD was plug-play...

ALL IS WELL AND GOOD NOW OSD data overlay is here ... except for one issue ...


I have mounted the cam on servo for movement, when I move it , the cam reboots and so does the OSD ( no overlay comes until i manually press the reboot button)


setup wise i have a separate LiPo ( 1000mAh ) for the FPV radio OSD and the CAM ... so i think its something to do with the  OSD power ....

Any help here ??

we discussed this topic many times before, i think you should power Servo individually.


refer this: http://copter.ardupilot.com/wiki/common-servo/#connecting_the_servo_to_an_apm2x (http://copter.ardupilot.com/wiki/common-servo/#connecting_the_servo_to_an_apm2x)

this included cutting the servo wire right ? I was thinking of a way where no cutting or anything is needed ..


Title: Re: MinimOSD - APM - Servo Power System

without cutting, you need
individual bec to power FC,
remove power jumber in FC
and use servo function in FC to control(other than direct connection from RX to Servo)

.... well shit ....

ok .. so i just spit the wire, connect them as shown and they will work fine right ??

and once connected at those ports, i can control them via my potentiometer right ?

i think you need to read again and again.

yes, that should work.

I prefer:
eject only red wire from connector of servo.
do same for one of the bec (From ESC)

Connect both ejected red wires(From BEC to Servo).

ok ... will try.

UPDATE ..

Just ha the first flight :D

APM is awesome :D

responsive yet smooth !~!


One thing i couldn't get is the altHold .. when i switched to it the quad kept climbing altitude ... how does that work ??

In the setting ( advanced parameter ) I went from .8 to 1.2 ... not much difference seen ..


THE ENDING WAS BAD though ... from a height of about 5m the solder of my POWER Module came off ... Quad dropped ... Nothing major damage though .
1> 2 props broke
2> APM Pins bent ( M1 to M4 ) , corrected them .
3> Zips of 2 motors broke.
4> Frame got bent from the center ( a curvature as the metal holder i had placed took the impact :D )

otherwise .. nothing major . All's fine.

your copter's hovering throttle is in between 40%-60% to work altHold better.


is perfectly described here:http://copter.ardupilot.com/wiki/altholdmode/#controls

so i cant make it still ??

there is no 'HOLD' ther .. all ALT there . :P it kept on rising ..

Check in mission planner if there is any huge variations in altitude readings when its not armed and still in ground.

and also check the readings are correct while lifting quad from ground without armed.

AKHILZID .. THANK YOU SO MUCH ! :D All the hlep :D

Quad finally flew and APM is amazing ! :D

Was fiddling with the ALT Hold mode and got what you were saying about the 40-60 thing ... cool stuff ..

It was soo breezy here and even without the GPS quad managed to stay in control :D


Now that all of that is taken care off back to the last few queries:

1. Servo powering - you said about the wire splitting .. ok will do that and report back.

2> Battery Life - I  dont get it here, i have 5Ah and 8Ah .. on the % I got about 7mins of flight time. with the 8Ah i got a good 16mins ! why such difference ??

Glad to Know that your quadcopter flown well.

i think you need to take more samples to confirm regarding battery. and need more details about components.


Title: Re: MinimOSD - APM - Servo Power System
Post by: parichya.gautam on February 27, 2015, 07:22:18 AM
yea i plan that ... components wise, the AUW is about 1.6KG with 5000mAh LiPO,Turningy 2836/8 1100KV Motors, SimonK 30A ESC ,1045 props,no GPS yet,( Awaiting for  Arun to deliver )

Post by: parichya.gautam on February 27, 2015, 07:48:43 AM
one thing more here ... the flying is all fine ... but when i switch back from alt hold to stabilize, the controls of the quad get reversed, the pitch and the ail ... i rearm the board and its fine again .... how to rectify this ?


Title: Re: MinimOSD - APM - Servo Power System
Post by: akhilzid on February 27, 2015, 08:39:38 AM
maybe you are using "Simple mode" along with any of these modes.


Title: Re: MinimOSD - APM - Servo Power System
Post by: parichya.gautam on February 27, 2015, 08:44:18 AM
i tried with simple, super simple and default ... same issue, the moment i switch back to stabilize from alt, the controls are reversed ... but if i move to sport, the controls remain the same ..

please post a screenshot of Config/Tuning ----> Flight Modes.

lipos charging, wil do once connnected.

but its just default , i have :
1.stabilize
2.AltHold
3.Sport
