Jigging and Dry Fitting a Fuselage

One way to try and ensure that there will not be any significant problems during the assembly, is to dry-fit parts.


  • Always fit anything possible so that potential problems can be corrected before parts are glued in place as it is much easier to eliminate problems before parts are glued together permanently.
  • Draw a centerline on your build board to assemble the fuselage over.
  • Pick one of the formers in the wing saddle area to begin with. This is the former to the rear of the wing saddle. It is erected perpendicular to the board and square to the centerline
  • Most kits have a former at the leading edge and trailing edge of the wing. This former simplifies keeping the receiver and battery pack in place.

Before You Glue any parts in place

Ounce you are completely satisfied that all the parts fit together, you should run through this final checklist before even taking the glue out of the box.

Have you...

  • Drilled holes in formers for the pushrods to pass through?
  • Cut pushrod exits in the fuselage side(s)?
  • Drawn all necessary alignment marks?
  • Drilled all holes in the firewall for the engine mount, fuel lines, nose gear mount and throttle pushrod? Are other holes necessary for items such as on-board glow-drivers?
  • Checked that the tank can be installed?
  • Ensured that the fuel tank does not interfere with the throttle pushrod? Have you trial-fitted the throttle pushrod?
  • Trial-fitted the nose-gear steering pushrod?
  • Planned for an antenna exit?
  • Planned for a switch and charge-mount location?
  • Ensured that nothing in the fuselage will interfere with a center-mounted aileron servo?
