I am a greenhorn to RC flight and multicopter. Still I managed to build my own quad and up to this point, everything worked fine.
I am using a MultiWii Mega All-in-One Flight Controller from http://www.diymulticopter.com/product.php?id_product=70 and some cheap ESC+brushless motors.
With the MultiWii 2.1 firmware, I should be able to use throttle+roll to arm/disarm the copter. This does not work.
The settings #define ALLOW_ARM_DISARM_VIA_TX_YAW or #define ALLOW_ARM_DISARM_VIA_TX_ROLL in any combination dont have any effect.
But it is possible to use the MultiWii-Conf and map ARM to a channel. Is there another way to programm the Throttle/Roll-combination to arm the quad?
Maybe in relation to this is another problem with the pins at the FC: in the description of the Mega All-In-One FC pins 2,3,5,6 are used for a quadx, but these do not work either -- I have to use pins 1,2,3,4. Might this be an indication, that there is a overall problem with the firmware? I have to use #define FREEIMUv043 // same as FREEIMUv04 with final MPU6050 (with the right ACC scale) in the combined IMU boards section. Has anyone similar problems or is using this specific flight control?
Many thanks in advance for tips, tricks and hints of any kind - I am here to learn
