Wing instructions:

The circles on wing section prints are for alignment purposes when trimming off excess stock from printing on regular 8.5 x 10” printer paper.

Start with pinning down leading and trailing edge stock.

Mount wing tips with first ribs together before pinning down to the ends of the wings.

Glue upper spars first, without gluing onto center ribs.

Set dihedral, glue spars into place on center ribs.

Glue lower spars in place, sand flush before adding central aft sheeting.

Add sheeting to leading edge as desired.

Add servo sheets between ribs if desired to add ailerons.

Fuselage instructions:

Cut 3 lengths of ¼” dowel stock at 20”.

Test fit spacers prior to mounting, gently sand if necessary to ease the fit.  It’s advisable to use PVA or 30 minute epoxy to mount spacers, gluing tail section where the dowels join while the spacers are dry fitted in place after the wing has been test fitted.  Tape in place on the tail section prior, or if you must, put a light small dab of CA to just keep them tacked together, since you may need to refit and adjust afterwards once the wing is set in place.  Complicated, I know sounding, but it makes sense during construction.

Second spacer is 4 ½” from tip of front spacer/motor mount.

Third spacer is 8 ½” from tip of front spacer/motor mount.

Trim right, down thrust on leading edge dowels as desired before mounting front spacer.

Notch second spacer based upon the angle of dihedral set from building the wing.

Cut two lengths of ¼” dowel stock at 2 ½” for rubber band mounts.

Notch area on the fuselage/dowel stock before gluing in place, forward and aft of wing placement.

*Optional, remove lower dowel stock from aft section of plane behind third spacer to help with center of gravity only if necessary, in most cases it is not.

Additional tips:

Add a mounting plate to top section of stock where the three dowels join for a flush surface to mount the elevator.

Reinforce inside center wing sheeting area with stock as needed to prevent compression from rubber bands.
Add lower sheeting stock between the ribs with an exit hole for pulling servo wires through in central section of wing.

Ailerons being optional, it’s still a good idea to include the stock in the wing for them and add some string to pull servo leads through. 



* April 2023 Update and supplement for build instructions for current generation and past were applicable.


Adding an aft, diagnal spar to the wing tips may be helpful.


Setting the end/tail area dowel stock after the wing is positioned may help with keeping alignment correct.


Dihedral measurement for dual purpose, tail feather only control or adding ailerons measures 1" from wing tip to center of wing.

The nature of the cuts on the kit relies upon tight fitting connections to maximize natural tensile strength, a very gentle, light, tactful amount of sanding may be necessary to avoid splitting the stock on some of the connections.  PVA or 30 minute epoxy is recommended for use rather then CA due to the tight fitting connections.

Setting the dihedral, center ribs being sadwitched/layered together, score the bottom edge of the balsa, forward and aft sections lightly to achieve best results for a clean bend.  Avoid cutting all of the way through, bend the stock at the correct angle approach. 1" height between the wing tips to the center gap for both 3 channel, and 4 along general use and configuration.  1.5" gap for strictly tail feather control.  No dihedral is needed for a sport model type of build. Top, aft sheeting takes some coaxing to not require scoring for a concave bend but is optional should one choose to do so.

*2023 kits were made with typically denser balsa stock, 2024 versions were made with lighter stock so the lightening hole stock provided can be glued back in, cross grained to strengthen the model without worry of additonal weight being added.
