RE: Official F27 Stryker Part 8: Beginners to Custom Darkness
Next is to line up the hinges with the elevon. I have used 5/16 x 1 1/4 and also 3/8 x 1 1/2 aileron stock. My personal choice is the 1 1/2 because if you have too much (???) surface area, you can allways dial in expo or use dual rates and lower the throws. BUT if you go heavy (big battery, fiberglass, etc...) you will want all of the throws you can get. The heavier planes come in at well over 45mph and do NOT like to land slow, so you will need MAXIMUM deflection to keep the nose up while coming in !!!
Mark the hinges and use a hobby knife to CAREFULLY slice an opening for the hinge. The key here is to ensure the knife does NOT exit the elevon. If it does, the elevon is junk and you will need to get another one. TAKE YOUR TIME HERE .....................keep all fingers and blood to yourself !!!
You will need to slide the elevon back and forth in order to seat the hinges while pushing down.
** THIS IS THE HARDEST PART OF ALL...... KEEPING THE HINGES FROM BENDING, and you will also need to keep the hinge in place so it will not get buried into the wing as you press and wiggle the elevon into place. You can use a "T" pin, (or a toothpick) through the hinge on the wing to keep it in place while you install the elevon.
If you use the toothpick, you will just cut it flush on top and bottom AFTER CA dries.
Notice in #3 picture, the Bass trailing edge and elevon are longer than the wing..................this is done so that the elevon or the bass wood does NOT split. If you try to cut a slice for the CA hinge too close to the edge, it WILL split !!!!
We can trim it to size once the glue dries
