Hello, after a long time of reading many topics in this forum I have dared to create a new topic.
I decided to build a boat with a gasoline engine after seeing this
although in my design, I made some modifications to be able to use my boat in waters with a bit of waves.
I built the boat with a length of 3.5 meters, and I used a yamaha 6hp engine that I already had.
the electronics so far is very simple, a pixhawk 2.1 with ardurover 3.5, a pair of radio rfd900, a taranis x9d and a pair of bec.
The accelerator is in charge of a servo savox of high torque and waterprof.
I have done tests in the sea in 2 occasions with the control in manual form, the first time it did not work very well, because for steering control I used a servo that although it had a lot of force was very slow.
8 "Stroke: 115 lb Thrust Linear Servo
This servo did not protect it well and finally it was damaged by salt water.
then I asked for another servo similar, a little faster and with a little less push
8 "Stroke: 25 lb Thrust Linear Servo
also perfect the place where the servo is located so that no water enters and install a teleflex to transmit the thrust of the servo to the motor.
on this occasion the boat worked very well manually, I had complete control of the movements, this was very nice.
although in an automatic way it did not work very well, it was normal to adjust the autopilot, so I took the boat out of the water and returned happily to my house with the intention of the next day to continue the tests, but made the mistake of leaving the boat on .
the next day the battery was dead, and as I had left the boat turned on so long were the logs of the previous day and the worst thing is that my steering servo did not work, I started the engine and the battery quickly took charge, but the servo just as fast moves of push and pull, it moved only less than 1cm, wrote to servocity because I suspect that the driver was unconfigured.
I have dared to create this thread because I hope to receive help from the community, someone knows if it is possible to reconfigure this servo.
or is it better to buy a new one? (They are not very cheap) and I think they are very delicate.
It will be that I can find a servo ready to use, more robust.
will it be better to make a customized servo?
the reliability of all the components is important since it is a big boat, and although I use it on a very lonely beach, I would not like to lose my boat.
thanks for your help.
