FB Jets Dolphin S 

Step 3: Forward Fuselage 

 

  Once the nose gear and servo assembly is completed, install the retract unit back into the 

fuselage , prior to installation place a very small dab of thin CA into the mounting screw 
holes first if using the factory provided sheet metal type screws.  

  Airline routing should be neat; it is recommended that the pneumatic valve equipment be 

installed as far forward in the fuselage as possible. The prototype was built utilizing a Jet 
Central electronic dual action valve for the retracts and a Jet Central electronic single 
action valve for the brakes. Remember to keep equal lengths of air lines when creating the 
right and left side run to the retracts and brakes to ensure even operation. 

  The Dolphin S is supplied with brass airline connectors, the prototype used the male end of 

the fittings glued into the fuselage at the wing junction for easy wing connections.  
The female ends were left loose with extra length of tubing protruding from the wing halves.  
A 1:1 scale drilling template and C.C fixture was created to locate the male connectors in 
the wing root area of the fuselage and can be found in Appendix A of this manual. 

 

 

 
Battery Mounting 

 

The choice of the battery technologies to be used is up to the builder’s discretion.  The goal of the 
build was to achieve proper C.G. without the need to add dead weight.   The prototype model 
required that weight needed to be located as far forward as possible to achieve the proper C.G.   
 
To achieve proper balance, two 5000 mAH LiPo hard case packs were used; one for the ECU, and 
one for the receiver.  A voltage regulator was used to create the required voltage level for the radio 
system.  
 
It is recommended that the batteries are mounted in a position to allow for easy removal for 
charging and maintenance no matter what technology is used.  There are many methods available 
to secure the batteries, a few include mounting with adhesive backed Velcro™ or using zip ties 
such as ty-raps on removable mounting plates etc.  It is the builder’s discretion to provide the 
proper securement method to ensure safe operation, maintain proper C.G., and allow quick access 
in case of battery emergencies.
