Had another negative encounter, it's been a few years since the last one, just an uneducated ******, going on about drones being illegal yada yada yada.    :-/
Still that didn't spoil my flying time, had an absolute blast  ~~

DB that just means you have shed loads of props in the first place ;-)

Just had a thought, even with all the crashing I've done, I haven't bought any replacement props in over a year ~~

multiwii v2 speed controller issues

hi i have just bought a quad copter and have had nothing but issues

on power up i have no throttle till stick is at 50%
when power begins motors all start at diffrent times

some one please help im new to this hobbie and this was my first  one ive spent over £200 and now im stuck


You probably need to calibrate the speed controllers to work with your radio system.

Tell us what quadcopter you have, what the speed controllers are and any other technical details you know and I';ll be able to give more specific advise.

That';s how i calibrate my speed controllers but i have SimonK firmware installed on mine. Yours may be slightly different, depending.

Unfortunately spending over £200 on a quadcopter does not guarantee success. You have to learn to understand how the systems work to use them safely and well. The easiest way to do this is to build it yourself. Multiwii flight controllers fly great - once you understand them well enough to get them properly setup and PID tuned. The learning curve is steep.

are you familiar with uploading a sketch.
multiwii v2.2 has an option to upload calibration for escs..
dont grow up,just buy bigger toys!!!!


The multiwii ESC calibration routine works very well if you know your way around the arduino software as fruitsalad says;

  /****           ESCs calibration                                 ****/

    /* to calibrate all ESCs connected to MWii at the same time (useful to avoid unplugging/re-plugging each ESC)
       Warning: this creates a special version of MultiWii Code
       You cannot fly with this special version. It is only to be used for calibrating ESCs
       Read How To at http://code.google.com/p/multiwii/wiki/ESCsCalibration */
    #define ESC_CALIB_HIGH 2000
    //#define ESC_CALIB_CANNOT_FLY  // uncomment to activate
