Build Tips

Initial Build
Retract & Strut Assembly
  • On recent production, the Fin has the Spar Tube factory glued into it. In that case, simply plug the fin onto the fuselage, plug in the rudder servo, seat the fin and attach with the provided screws. (No additional glue is needed).
    Clean the Recepticals
  • On initial G2 shipments, we've noticed a few models that have the retract strut adapter pins installed on the incorrect sides, resulting in an aggressive toe-in angle in the main wheels. To correct:
    Install Spars in Fuselage First
    • Remove the retract units from the fuselage.
    • Use a 1.5mm and 2mm hex driver to remove 2 set screws from the sides of the aluminum strut and 2 set screws from the sides of the retract housing. These set screws secure the strut to the pin, and the pin to the retract unit.
    • Slide the strut off the pin, then remove the pin. Swap the pins from left to right and re-install, being sure to use blue thread lock on the set screws, and ensure they rest against the flat spots on the pins.
    • Re-install the retracts into the fuselage. Do not use blue thread lock on the retract mounting screws.
  • Please set your transmitter CH5/Gear Travel to +-125% to ensure the Gear Sequencer will follow the transmitter and function properly.

  • FlexJet G2 Wing Installation
    • The G2 has stronger receptacle tubes in the fuselage to accept the wing spars. It is possible that there could be a little residual glue in the tube or on the plywood near the plywood rib. There also could be a slight misalignment of the plywood rib to the tube. This could make it difficult to insert the Wing Tubes into the Fuselage.
    • Test fit the Wing Tubes into the Fuselage (before installing the wings) using a twisting motion as needed. If it is too difficult to insert, use a #11 hobby knife to clean the plywood rib and the opening of the receptacle tube (a round file could also be used).
    • Once the wing tubes are installed in the fuselage, slide the Wing Panels onto the tubes and finish securing the Wing.
  • The Stab Linkage is located on the Outer-most hole from center at the Stab Arm End (aft end). Check/Connect the Clevis/Pushrod to the Stab Arm.
  • The Stab Linkage is located the 2nd hole from the center at the Servo End. Attach the Stab Linkage to the Servo Arm.
  • The free Stab end Arm and Clevis can be turned together to make pushrod length adjustments while checking. Screw the Arm in place after correct trim is confirmed. (as described in Manual P. 11, Step 5)
  • It is likely that your Ventral Fins are already installed, so you may not have to install these per the manual.
  • Your Side Fairings behind the stab are likely NOT installed (change to prevent shipping damage). They are likely packed with your missile rails. Please glue them onto the aft fuselage with CA or Epoxy before installing the tail cone.
  • Please check the glue joints of the Rib in the fuselage socket where the wing attaches. Add some medium CA as needed. There have been several reports of inadequate glue.
  • When re-installing the Tailpipe, a good technique is to get the tailpipe aligned with the back edge of the fan as close as possible, then 'pop' the aft end of the tailpipe with the open palm of your hand and it will 'jump' forward into place.

General Tips

  • It is possible to scrape the ventral fins and tail cone on the ground on landing. You can put a couple of layers of clear tape on the bottom of these to reduce wear
  • As described in the manual (P. 9, Top), Arm the retracts before each flight.
  • Please read the Quick Trim section of the manual carefully, noting it has the ability to fine tune the Stab Trim in pitch and roll Before and/or After flying.

Aura Tips

  • For Aura new comers, note that ANY Aura servo port (ex. Nose Wheel Steering) can be subtrimmed using the Aura Config Tool (set View->Advanced). Config Tool->Servo Ports->Subtrim. Be sure to WRITE to Aura to utilize the new settings. Most other parameters can also be adjusted in the Aura Config Tool
  • For Aura veterans, please note that the FlexJet uses Ch5/Gear for Retracts (2 position switch preferred), and Ch6/Aux1 for Aura Flight Modes (3 position switch preferred). This is different than most of the previous 5 channel SPNP planes.

Please consult the FlexJet Manual for Build instructions.
