the star frame is basically the same board and trigger as the ego8, the board gives you pretty much unlimited adjustability and the added adjustability of the magnetic trigger
it is very simple to fit, you just have to drop the original frame off, plug the solenoid and eye wires into your new board, then screw the frame back on and swap the asa to the new grip frame
but i think it comes with a brief manual to show instalation and modes etc.
hope this helps
