How to make an electric remote control boat?

In fact, electric remote control boat is easy to do.

Simply put,

The hull structure is easy to manufacture.

In addition, a servo control system that can control the direction and a control circuit that controls the rotation of the main motor are needed.

This control system can be sold in a model shop or removed from a broken remote control car for replacement.

It is easy to understand that the main motor controls the forward and reverse rotation separately.

The steering gear, that is, the one that controls the direction, can be considered in the form of electromagnet or motor.

Electromagnets can only distinguish between left and right (adding a tension spring can realize linear stroke)

Simple structure, easy to do.

Small servo motor is more effective for direction control.

It is also important to note that

Generally speaking, many models are now blindly seeking high-power motors.

What makes a boat look like a speedboat?

It will be boring to play in a smaller lake for a while.

Generally speaking, I personally think that the motor power of a model ship with a length less than 1000mm should be less than100 w.

Otherwise, the leisure meaning of playing with boats will be lost.

The hull can be made of foam.

The advantage is light weight, but the disadvantage is that it is not very waterproof and easy to corrode.

You can do it quickly with wood.

The advantage is that the gold carving is exquisite after careful carving, and any paint is not afraid of corrosion.

The disadvantage is that it is not easy to find such a large homogeneous board and it is not easy to dig without special tools.

Nylon plastic or metal can also be used.

This requires a mold.

The cost is higher

But it's a little durable
