RE: Proboat hydro
Actually, ( a moderator can correct me if I wrong) but unless you work for a company that offers product for R/C boats, or you are the owner, or you are sponsored you cannot promote, but
if you are a plain regular RCU member, their is no problem for you to recommend one or more brand or one or more companies.
Their is only one company that I know of that which we cannot mention.
