Ya the websites Roy posted are good, and Ernie and Erica also sell RMH plans as well.
However, are you interested in a rocket stove or a rocket mass heater? From my understanding RMHs maybe have a bit of smokeback but a rocket stove shouldn't have any more smokeback then a regular wood stove.
The book Rocket Mass Heaters by Ianto Evans is also very good and also includes how to build rocket stoves and pocket rockets.
