Hey guys,
Im modding my 42099 into a strong crawler with a wider body, wider axles, 2x buggy motors and a buwizz 3.0 battery. I also want to implement 4 wheel steering. A cool feature of the 42099 I want to keep is the axles which can twist independent from eachother. This makes a mechanical 4 wheel steering linkage not possible, so I want to build the 4 wheel steering by seperate motors on each axle (I think thats what they are doing here: BuWizz app tutorial - 4 wheel steering using Tracked Steer Module - YouTube).
After connecting the buggy motors to the battery I have 1 power functions port left and 4 powered up ports for the steering motors. I have tried implementing PU L and XL motors, but the buwizz app can only succesfully calibrate 1 of the axles through the 'Center Steering' module. In the video the Buwizz guys use 2x servo motors with the 'Tracked Steering' module, but I can't find those servo motors anywhere. Only fake ones, which I tried and worked for a few minutes, after which I fried something inside the replica motor and it stopped working with smoke coming out .
I'm starting to get a little bit desperate now so I think I need the help of this forum. I tried asking Buwizz, but I got some vague answers and feel like there's some translation error. Does anyone else have a solution as where to find servo motors or a different solution that would fit the needs of this MOC?
Thank you in advance!
