what is the best starter radio kit i should get. Originally i was going to make a basic thethered sub, consisting of 4 cheap hobby motors in a series circuit, connecting with the butons and probably tha batteries on land. But now that i think about it im thinking that if im gunna invest in the motors the approximatly 200 feet of wire, buttons and batteries, it will probably be cheaper then the radio kit but the radio kit would be an invest ment in the long run. so basically what i am asking is what is the easiest beginner starter kit that i could use to make a basic basic sub. thank you for your time and help.
