Hello everyone!
I am trying to assemble a boat with APM to move autonomously. Since I am using 2 BLDC-s to move the boat, I am using the Rover firmware with SKID_STEERING_OUT and _IN turned on. In the documentation it is written that in this mode output channel 1 should power one motor and channel 3 should power the other.
On channel 3 it is working perfectly with my joystick through a laptop and a radio module.
The problem is it seems that channel 1 provides a square signal but there is no PWM change however I pull the throttle up or down.
Parts that I’m using:
APM 2.6 with the latest Rover firmware
Hobbyking 30A ESCs
930KV 2212 BLDCs
FPV 433MHz telemtery pair
3dr power module
2 cell LiPo battery
Thank you in advance for the answers, if anything more needs to be specified, I will!
My best guess is that you have the R/C input connected to the APM incorrectly. Personally, on a mode two transmitter, I use the right stick to control everything - that usually being the ailerons and elevator on a plane. So, I assign the Aileron (right/left) to Channel 1, and the Elevator (up/down) to Channel 3. You can do this by plugging the leads from the receiver into the appropriate APM inputs.
A good way to test which is which is to connect a servo to the R/C receiver outputs, then move the sticks until you figure out which stick does what - then plug the one for throttle into input 3, and the one for steering into input 1.
