Instruction Manual
Introduction: This great looking little racer can trace it's lineage back to the very popular Rare Bear parkflyer racer. This was a very fast parkflyer based on the Reno Racers that was amazing fun to fly, was very tough and it became a firm favorite extremely quickly. The Goblin carries on all these traits coupled with great looks and attention to detail. It comes with a choice of 2 eye-catching color schemes either yellow/black/silver or pink/blue/black and factory applied decals.
Read this instruction manual fully so as to become completely familiar with the features of this product before operating. Failure to operate this product correctly could result in damage to the product, personal property and cause serious injury. This is a sophisticated hobby product and is NOT a toy. It must always be operated with caution, common sense and some basic mechanical ability. This manual provides instructions as to the assembly, safe operation and maintenance of this hobby product.
1 2 3 4 5 Components: 1. Main Wing with 2 x pre-installed 9g servos, fitted pushrods and control horns . 2. Fuselage with pre-installed motor, prop, spinner, ESC, 1 x 9g servo and fitted pushrod. 3. One piece fin and rudder. 4. Tailplane and hinged elevator with fitted control horns. 5. Fuselage underbelly pan.
Warning: Before you start to assemble the Goblin please read through this manual as there are some important notes and updates you need to be aware of before you start. Assembly: Before you glue the wing permanently to the fuselage please check the operation of the ESC. The Goblin is a one piece model so the wing is permanently attached to the fuselage. If your model has any residue paint on the surfaces to be glued then either lightly sand or prick the surfaces with a pin to help the adhesion.
Feed the aileron Y lead connector through the opening behind the ESC. Carefully tuck the leads and connectors through into the receiver/battery bay and position the wing onto the fuselage wing seat.
Ensure the wing fits snuggly and stays perfectly aligned to the fuselage as the glue sets. Once again remove any residue paint or prick with a pin the rear of the fuselage and the underneath of the tailplane where the 2 surfaces are to be joined together.
Apply a good foam adhesive or slow setting CA to the rear of the fuselage and the underneath of the tailplane where the 2 surfaces are to be joined. Carefully position the tailplane onto the seat at the rear of the fuselage, ensure the tailplane remains perfectly aligned with the fuselage and wing as the glue sets.
Again remove any residue paint or prick with a pin the area where the fin/rudder assembly is to be attached to the fuselage. Do the same with the underneath of the fin/rudder assembly and the locating tongue on the bottom of the rudder. Apply a good foam adhesive or slow setting CA to the rear of the fuselage and the underneath of the fin/rudder assembly and locating tongue where the 2 surfaces are to be joined.
Carefully position the fin/rudder assembly onto the seat on top of the tailplane making sure the tongue on the rudder engages properly in the rear of the fuselage. Ensure the assembly remains perfectly aligned with the fuselage as the glue sets. Install the receiver of your choice, minimum of 4 channels. Important Note: As the Goblin is quite a fast model we recommend that the EPO hinges of the ailerons and elevator are reinforced with a good quality hinge tape such as 3M Blenderm tape.
Update: The picture above shows the attachment of the elevator ball links. If your model has been supplied with ball links then please replace them with the supplied clevises. You will find a packet of 4 clevises with keepers in the box. The clevises improve the control authority of the Goblin. When fitting the clevises slide the clear plastic keeper over the pushrod first then screw on the clevis. Adjust the length to achieve a neutral control surface then slide the keeper over the clevis to secure it.
Do the same with the ailerons and replace the ball links with the clevises. Again remove any residue paint or prick with a pin the area where the underbelly pan is to be attached. Apply some medium or slow setting CA to the area.
Carefully position the underbelly pan and hold in place until the glue sets. The assembly of your Goblin Racer is now complete.
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.
Setting Up. Now that your Durafly Goblin Racer is built you are ready to set up the model for its maiden flight. When setting up please use a battery as recommended further on in the manual (max battery weight is 170g). For safety please remove the propeller when binding your transmitter to your receiver. Plug in the servo connections to the connection points of your receiver (please be mindful of polarity).
Recommended Center of Gravity Measure for the Center of Gravity from the leading edge of the wing at the center section. Balance the Goblin nearer the forward 45mm mark for initial flights then it can be moved rearwards as you get used to the flying characteristics. Do not go beyond the 50mm max rearward position. Suggested Control Throws Ailerons Recommended Batteries We recommend a 4S lipoly battery of 1000mAh to 1800mAh capacity.
