Section 2:
Assembling the elevators
Step 1.
Carefully remove the elevators from its protect
tive plastic.
Step 2.
Insert plastic washer over elevator rod.
Step 3.
Lubricate the shaft with some thin machine oil.
Step 4.
Insert the shaft into the elevator bearings.
Step 5.
Fit plastic washer between elevator horn and
bearing. Make sure no lateral play is present
and secure horn with 4 cap skrews. (use loctite)
Step 6.
Locate the 2 elevator servo’s. Install servo’s in
powerbox system to electronically centre the
servo’s. Check for correct operation.
ke
Step 7.
Mount metal servo horn to servo and secure
titanium ball bearing rod to servo horn. Check
that bolt holding pushrod to servo horn is se
cure and use a locknut or loctite.
Step 8.
Drill holes for servo and mount servo by means
of 4 skrews.
Step 9.
Secure other end to elevator horn. Use same
method as on servo horn.
Make sure that
pushrod form a 90 degree angle with both
horns! Make sure no mechanical slop is pre
sent!
Step 10.
Repeat steps 1—9 for other elevator. This com
plete this section.
NB: Make sure both pushrods are of equal length and
that installation is a mirror image of each other!
This completes this section!
Items Required:
1. Elevator L & R including bearings
2. Metal servo horns (2)
3. Titanium push rod assembly (2)
4. JR DS8911 servo (2) (15Kg minimum)
5. Powerbox and radio equipment
6. 1mm drill
7. Hobby knife w/#11 blade
8. Skrew driver
9. Straight edge & Ruler
10. Lubrication oil
We recommend to set up the two elevators as elevators.
Some experienced pilots may opt for an elevon set up.
Please follow your own experience in doing so. We
have tested both and both work just fine. This manual
will how ever continue for elevator set up and conven-
tional ailerons in wing.
It is very important to use correct servo’s and push-
rod assembly!
A minimum torque of 15Kg per eleva-
tor is needed. The new JR8911 is just what you need. If
you can not find such servo’s, then 2 x 8511 servo’s
Servo’s must be synced by means of JR matchbox!
It is
very important
that
no slop
is present in the ele-
vator configuration. Any slop will be converted to flut-
ter. Flutter will destroy the elevator and make the model
uncontrollable. The ailerons are actively hinged to wing.
This method is very strong and durable and will last the
life of the model. Take advantage of this incredible
technology and see how quickly you can complete
wings!
