Ok I saw my mistake on the Wiring Table, So pins 4 & 7 from Uno should go to pins IN3 & IN4 at the Motor Driver. I have made the edits to the steps. Thanks for catching the error!

I used 0.18mm for my layer height

Yeah the preview doesn't show the correct image but, if you download it the Drive Gear STL is correct.

The NRF transmitter has 2.4 GHz and it supports data rate from 250 kbps to 2Mbps. Now I'm gonna be honest here, I am not sure what data rate I am getting but, I know you can set data rate by adding the code: radio.setDataRate(RF24_ 250KBPS); I hope this helps!

No I didn't retrieve it, maybe I need to build an arm that attach to the car to retrieve it...

Yeah the connections for NRF24 could be tricky. I used pin 9, 8, 13, 11, and 12. My pin 8 is connected to CE, this pin can actually be connected to any digital pin. However, pin SCK, MOSI, and MISO has to be connected to 13, 11,and 12.If you are using 9 and 10 as CSN and CE. Then you need to change the Arduino codes. where is has: RF24 radio(8, 9); //CE, CSNchange the two number so it corresponds to your pins.

Hi, in the Arduino code the left potentiometer or variable resistor is used to control the voltage into the motors, therefore, control the rotation of the propellers.

Oh I used B50K on the left and B20K on the right.

Yes the cross horn will fit

Hi, sorry for replying a bit late. The fin is attach to a cross type horn of the servo motor. you should be able to just push them together. if you do not have the same type of horn as my. you can just design a new fin to fit yours. The same thing with the mast and the boat. line up the hole at the bottom of the mast with the rectangular part at the center of the boat and push them together, some sanding might be required to make them fit. Lastly, the motor driver sits in the front the mast and the controller sits behind the mast. Sorry, I don't have any new pictures to explain what I did, because I disassemble my boat to make something else. Hope this helps PS if you have the electronics all setup you can just design a new boat around it. I highly recommend you do that cause is really fu…
