I think that the 3 wires from the fan goes to a speed controller.  The timer then plugs into the Futaba type connector on the speed controller.

I haven't played with the 18mm fan and can't find any specs on the internet, just keep things as light as possible.

Here's a picture

The unit has a brushless motor.  The three wires go to a 'brushless motor speed controller' (aka a brushless ESC).  The three wires can be connected in any order to the speed controller.  Just plug it up and try it.  If it goes 'backwards', swap any two wires over and it will go 'forwards'.

Actually.. looking at the parts pix... Fit an Rx instead of that "timer' 
Likely same weight/size if not Smaller... then You can control the engine from your transmitter.
Useful when one needs save their model :-0
