After you manage all the necessary kits, it’s time to work. Use your backyard or your garage as your workstation. Working in a sequence is a must, or there will be a huge possibility that you will mess up. Then how will you proceed to work? Let us show you the sequences:

Get To the Framework

Set the Bearings

Now, it’s time to set the bearings with the mainframe. For that, you need to dig the exact size of the holes and then attach it through shouldering. Before that, you should attach the small gear with the bearing.

Attach the Back Wheels with Main Frame

Take the hollow pipe and get it through the bearing at the backside. It is because you have to attach the back wheels first. Then make the connection permanent with shouldering kit.

Check the Engine and Its Exhaust

To make a gas-powered RC, you will need a stroke engine which runs through petrol. As you are using an old engine, you should check its exhaust and combustion chamber properly. Another thing to do is attach a small gear to the engine, which will further connect with back wheels through a small chain.

Make Space to Set the Engine

Then make a platform to set the engine into the frame. You should use the screws because the engine needs to be secure inside the frame.

Attach the Remote Control Device

After you are done with the wheels, get the remote control device and attach it with the metal plate which is placed on the front wheel. Then check if it is working or not.
