Goblin Racer Instruction Manual

Important Notes :
We highly recommend that you follow these important steps before flying your Goblin Racer and
you may wish to do these before you start the assembly.
The down thrust on the motor needs checking, the gap between the spinner and the top of the
fuselage should be between 4-4.5mm as shown in the picture below.
If your model only has a gap of about 2mm then please do the following :
1. Remove the spinner and propeller assembly so that you can access the 4 motor
screws that mount the motor to the firewall.
2. Remove the 4 mounting screws and ease the motor forward so that it is clear of
the cowl. You will need to push the ESC through the firewall slightly to do this.
3. At this point it is a good idea to check the 4 screws that hold the motor to the
metal cross mount to ensure they are tight.
4. You may find that there is a washer already behind the top mounting point. If so
either replace this washer with a thicker one or add another washer. The total
thickness of the washer(s) wants to be between 1-1.5mm, this will then give you
the required down thrust.
5. Refit the motor with the washer(s) behind the top mounting and tighten the 4
mounting screws.
6. Whilst the propeller assembly is removed it is best to bind your receiver to your
transmitter and check the settings. Also ensure the control surfaces are set to
neutral and check the control throws (see "Setting Up" on the next page).
7. Before refitting the propeller and spinner assembly it is a good idea to check the
balance of the propeller and balance as necessary.
8. Refit the spinner backplate and then the propeller, washer and nut. Ensure the
propeller trailing edge is against the locating pegs of the backplate when
tightening the nut and washer. This is to ensure that the spinner cone aligns
properly with the backplate.
9. Refit the spinner cone and tighten the 2 screws.
