using a small amount of 5 minute epoxy, leaving about 1" extending under wing.
9. Now run the excess antenna back and forth through the flutes in the tiplet, leaving a couple
inches extending out the back of the tiplet.
Final Setup
1. Find the micro control horns and install them in the top of the elevons. Just push them
through making sure that they are lined up with the control horns of the servos. Cut the
covering away from where the micro control horns sit. Now permanently attach the horns with
thin CA. Once that is dry, you can cut off the post sticking through the elevon.
2. Make a small “Z” bend in the end of both music
wire pushrods. Attach the pushrods to the elevons.
Make sure that your servos are centered, then cut the
pushrods to the correct length. If you are using the
Dubro micro EZ-Connects, all you have to do is slide
the pushrods through the EZ-Connect and tighten the
screw making sure that the elevon has a very slight
reflex (up angle) to the wing. If you are not using the
EZ-Connects, mark the location of the servo arm on
the pushrod and make another z-bend. Then insert
the z-bend into the control horn of the servo. I
recommend the Dubro EZ-Connects as it makes for a
MUCH simpler setup.
3. The battery is attached using Velcro. I suggest the use of Industrial strength Velcro as it is
much stronger. First lightly “paint” some 5-minute epoxy in the battery bay (you can thin the
epoxy by using denatured alcohol) and let dry. Then position the battery where you can obtain
the correct C.G. This is where you will install the velcro. If you are using a single battery and 2
speed controls, you will have to make a “Y” connector, if you use two smaller LiPoly batteries
you can connect them normally.
4. Attach the motor to the motor mount using the tie wraps included. Make sure that you
tighten the tie wraps fully. Attach the prop to the motor making sure that the letters on the
prop are facing forward. Make sure that the rubber adapter doesn’t rub on the motor. If you
are using 2 ESC’s, plug the motors into their speed controls. If you are only using 1 ESC (no
rudder), snip the connectors off of each motor and solder the red motor wires to the red ESC
wire, then the black motor wires to the black ESC wire. Be sure to cover the solder joints with
heat shrink or electrical tape.
