I bought a second hand Alfa sub and a WTC. I have never built an r/c submarine and the alfa or the WTC dont have instructions! All I have to show for 600 dollars is a glass shell of a sub and a plastic tube(I am not impressed)
Where can I get instructions? Also the wtc is one big watertight compartment and one compartment with a hole and what looks like the propel tank. Is this right? How does this all work?
