Elevator (Ele) Step 1

Pin the Stabilizer back down over your plan lining up the Center marks again

We are going to use a spacer between the Stab and Elevator to keep the elevator from rubbing or binding on the Stab after its built and wrapped. it should move freely and easy when your flying.

Using a scrap piece of 1/16 or 1/32 or a piece of cardboard as a spacer, put the spacer between the edges of the Stab and the elevator tips, then cut and pin a 1/4 x 1/4 piece of balsa up tight against the spacer to the outline on the plan.

Do this on both sides of the Stab

Elevator Step 2

Once the 2 sides are pinned in place, remove the spacers.

Then cut to fit snug the leading edge of the elevators from one end to the other, don't make 2 halves, use 1 piece of 1/4 x 1/4 balsa stick (preferably one of the stiffer pieces of stock you have) to span the distance. pin this piece down once you know it fits nice.

Remove all the spacers

we will cut the center part connecting the elevator halves out later.

You can now remove the Stabilizer from the plan sheet

Elevator Step 5

Starting on the outer tips, left and right sides, cut and place the diagonal bracing in

(the reason to do it this way is the angle of the cut you make should work on both sides.)

Then go across the bottom filling in the rest of the bracing.

Elevator Step 7

Once dry, take out all of the pins and use your finger to hold down the plan protector or wax paper and slowly unstick the ele from the plan sheet.

We will be using the 1/4 x 3 sheet you used on the Stab Center piece to make 2 Control Horn blocks

You can either transfer the measurements onto the wood or trace the part you need from the elevator, the video explains how to take 1 measurement and then trace the ele over the wood for the control horn blocks.


This video is Steps 7 - 8

Elevator Step 8

Measure the distance between the bottom and the top of the control horn block
(going from the leading edge towards the trailing edge)

Transfer the mark onto the 1/4 x 3 using the flat edge of the balsa as the starting point.
(run the grain of the wood parallel with the leading edge of the ele.)

Take your Ele and place the inside center triangle over the 1/4 x 3 piece of balsa and trace it up to your line. then cut it out and sand lightly until it fits snug into the triangle.

(don't make it so tight it bows the bracing)

Using the same procedure or the block you made for the left side, make another for the right side.

Glue the blocks in once they fit snug

Lightly sand the ele smooth all the way around on top and bottom sand all outside edges smooth.

Do not cut the Center piece out of the Elevators yet

Elevator joiner wire Or dowel option

We are going to prepare the Ele And Stab for hinges during these steps also, just take it step by step its very easy

Mark the Center of the Stabilizer trailing edge and the Center of the Leading edge on the Elevators

If your using a Center tool go ahead and mark the centers of both the elevator and stabilizer just score the whole length of the pieces

you can use a Piece of 3/32 scrap balsa by laying the balsa down next to the stab trailing edge then draw a line across the center.

Or use a ruler and get the half mark that way.

This vid is for getting the center marks and choosing the joiner wire or dowel

Joiner or Dowel choice

We want to use either a joiner wire or wooden dowel to lock the elevator halves together.

Joiner wire
To use a elevator joiner wire you'll need a piece of 1/8 rod, about 3 1/8" long from outside end to outside end it can be a little longer.
The 2 ends need to be about 1" - 1 1/8" long

If your using a Wooden dowel you need a piece of Dowel 1/4 round x 3 1/4 inches long

Mark the 4 approximate locations for the hinges on the Stabilizer on your center mark across the trailing edge.
We'll get more exact in a few steps
