Palmer opened the scoring inside two minutes, and emulated this fast first after the break as he netted his, and City's second just one minute into the second half.
Our third came somewhat fortuitously as a Tommy Doyle corner cannoned of West Ham defender Josh Okotcha and into the back of the net.
League top scorer, Delap made it four soon after as he smashed home his one-on-one effort for his tenth league goal in five games.
Palmer capped off a magnificent display by slotting an effort into the bottom corner, to secure a well-deserved hat-trick and three points for the team.
The victory extends our unbeaten run to 11 games, and leaves the EDS five points clear at the top of the Premier League 2 table.
