Hi, Could one of you marvels please help out on this, spent few weeks working out a project for a magic prop. But really doing my head in figuring out how to wire up. Will be using a YK04 receiver. STP3NF061 mosfet, with 100k resistor. Would like to power 2 motors via remote. Think have one sorted but unsure on adding 2nd one, especially the source side? Again any help much appreciated. Ahh sorry for the drawing, not too clued up an electrical symbols and schematics.
How to wire this up please :-)

The circuit looks OK except:
The unconnected MOSFET source should connect to the common GND connection.
Is the resistor there to reduce the voltage from the 9V battery for the first motor?
If so then when the second motor is added the current from both motors will flow through this resistor so when the second motor is switched on it will reduce the voltage for the first motor (and vice versa). To avoid this put a resistor in each of the wires drawn in red.
