Title: after arming unable to fly.. Post by: nitin0836 on September 29, 2015, 08:42:04 AM i have crius aiop v2 board*(multiwii code) .. i had arming problem for it.. i tried everything but could not arm it..
later i found out that i can set it up to get armed from channel 5... so i configured it and armed it with channel 5.. it is arming with channel 5 and when i give slight throttle up only 2 motors spin, even at different speed and the motors are not spinning continuously but instead they are spinning in PWM fashion ... and when i go on increase throttle the rest of motors start to spin... but they are all spinning at different speeds... because of this the quad is not able to lift and fly.. i have done following things..in multiwii 1.esc calibration.. 2.radio calib 3.accel calib 4.magnetometer calibration please help me Title: Re: after arming unable to fly.. Post by: Purush on September 29, 2015, 12:44:08 PM Nitin, I'm too building with Multiwii megapirate AIO board and was hit with same issue, I was able to arm the motor with Yaw, I use multiwii code and arming is set to " #define ALLOW_ARM_DISARM_VIA_TX_YAW".
For all the motors to spin in same speed you need to adjust the trim in Tx, set the trim for YAW,ROLL and PITCH equal to 1500 (may be +1) check with value with Multiwiiconf GUI, with this set when you increase the throttle all the motors will spin equally Title: Re: after arming unable to fly..

Post by: Darshan for multirotors on September 29, 2015, 09:23:44 PM As you say that even after you have done it manually(do you mean individually ) the motors aren't starting at the same time.. that means you need to a calibrate your escs through the fc..
That's why I gave you that link.. After you are done with that procedure, your motors will start at the same time... Title: Re: after arming unable to fly..

After you are done with that procedure, your motors will start at the same time... one more question i had .. when i push the throttle up,rudder right, roll right, pitch up.. all those values should increase and values should decrease for opposite direction am i right?? thank you very much for your help Title: Re: after arming unable to fly..

Btw did I you set your tx end points? |
