Make a 55mm WTC for RC Submarine EP. 3 Leak...........

[@neitoRC]

You need to secure the endcap containing the power switch to the rest of the electronic rack. Otherwise the expanding air inside the WTC will push the endcap out and leak when the piston tank is diving.

Comrade, you need to use a silicone sealant. That's what I do. no problems with tightness!

It is natural that this structure leaks. Because the piston is too big for the capacity of the pipe When the piston moves, the air inside is compressed When draining, it becomes negative pressure and sucks outside water

[@perotekku]

What RPM does the piston motor run at?

Vaseline is not good for rubber gaskets.
