I just bought a Qav 250 with 2208/2400kv after i finished it i was flying ok... Then wanted to add gps and lcd so i updated the firmware to v2.3 now i cant even get it a foot off the ground.. I did cal. esc,s etc In the firmware the this is the maximum value for the ESCs at full power, this value can be increased up to 2000 */ so i took it up to the max. and still the same so now i'am not sure where the problem is... Why can i not take max rate up to motors kv..?
Thanks in advance for any help Neil
Qav 250 motor problem
Re: Qav 250 motor problem
Which FC?
What did you change in the config.h file?
Cal'ed ESC from RX throttle channel or with the MW code?
What value in the code did you increase to 2000?
Was there an earlier MW code in the FC? If so did you run the "clear_EEPROM" sketch from Arduino before updating the code? If not this can cause issues.
Are you using the MWconfig.exe 2.3 version? If not this can cause issues.

Re: Qav 250 motor problem
Crius MultiWii SE V2.5 and i changed Motor maxthrottle #define MAXTHROTTLE 2000 Cal'ed ESC from RX throttle channel and not sure what mw code was on the FC when i bought it
I just set it up when i got it last week.. I did not use the clear_eeprom when i uploaded v2.3

Re: Qav 250 motor problem
Ok, load and run the clear_EEPROM sketch from Arduino IDE.
Cycle power and re-load MW 2.3

Re: Qav 250 motor problem
I did the clear eeprom and ecs cal. but now when i start to give it power it flips right over on it back If i hold the qav250 up and about half throtle it rocks back and forth and from side to side .. before i did the clear eeprom and but in the new 2.3 it would fly a foot off the ground great but couldnt get it any higher and stupid me didnt save the last gui settings .. could it be the pid setting they are roll P: 3.3 I: 0.030 D:23 Pitch is the same as roll Level P: 9 I: 0.010 D: 100 now i have got so lost in all this and dont know how many props i have gone through lol .
Re: Qav 250 motor problem
Odd so far.
Are you using the 2.3 Version of the MWconfig.exe? The version numbers must match.
Rocks back and forth may be an indicator that the P & I P/R PIDs are too high. You do have very powerful motors for a 250 quad. Reduce the 'P' on P & R to see if it helps (drop them to 2.0 for a start). The 'I's can be reduced also. That is near the 'P' values I use on my Warp Quad (very light and strong motors).
This test is done in Acro (rate) mode, correct? Holding it is a good way to get a feel for PIDs and to ensure all esc/motors are connected to the correct pins.
I keep a log of the PID values and other settings when I make changes so that I can see the progression and restore the values if I accidentally wipe them out.

Re: Qav 250 motor problem
Yes im using the 2.3 config wiring is right becuase i was flying it before the change to 2.3 the problem before was i couldnt fly more than a foot off the ground..
Will let you know how things work out
