AFTER YOU MASTER THE NEXSTAR
EP SELECT IN ITS ORIGINAL FORM
SpeedBrakes Training Flaps
After you feel comfortable fl ying the NexSTAR EP Select and you
want to improve its high speed performance, the fi rst thing you
can do is to remove the SpeedBrakes Training Flaps by removing
the six screws that hold them in place. The NexSTAR EP Select
was optimized to fl y with the SpeedBrakes instead of fl aps, so
if you remove them, you will have to re-trim the elevator (see
page 13). Without fl aps, the NexSTAR EP Select will try to pitch
down (nose down) until you re-trim it. Without the SpeedBrakes
Training Flaps, the airplane will fl y much faster at any throttle
setting and longer landing approaches will be needed. Also, the
NexSTAR EP Select will not brake as well on down lines and stall
speed will increase slightly.
SpinControl Airfoil Extensions
The second thing you can do to improve the high speed
and aerobatic performance of the NexSTAR EP Select is to
remove the SpinControl Airfoil Extensions. These extensions
at the LE of the wings are held in place with tape that can be
carefully removed. Once you remove these extensions, you
will need to re-trim your elevator to align it with the stab. The
SpinControl Airfoil Extensions produce the opposite effect
than the SpeedBrakes Training Flaps in pitch, so if you remove
both, the net pitch effect would be almost non existent (see
page 13). After you remove these extensions, the NexSTAR
EP Select will be faster and able to spin and snap. Also, the
stall speed will increase slightly.
Dual Aileron Servos
The Hobbico NexSTAR EP Select comes equipped with dual
aileron servo trays for dual aileron servos. If you wish to use
fl aperons you will need to upgrade your radio system to 6 channels.
To install the dual aileron servos, follow these instructions:
For this section you will need:
1
- Additional Aileron Servo
(same type as that
already installed in your
NexSTAR EP Select
1
-“Y” harness
2
-6" [152mm] Pushrods
2
-Nylon Clevises
2
-Silicone Clevis Retainers
2
-Faslinks
1
-Servo Mounting
Hardware
Set
1
-Screwdriver
1
-Wire Cutter
1
-Pliers
1
-Thin CA
1
-Trim Sealing Iron
❏
1. Disconnect the aileron servo pushrods from the aileron
horns and remove the original aileron servo.
❏
2. Locate the dual aileron servo trays in the wing. They are
located on the underside of the wing at the 6th bay in from the
wing tip. Trim the covering over the opening and use a sealing
iron to seal the covering to the tray.
❏
3. Use a 1.5mm [1/16"] drill bit and drill mounting holes
for the servo as shown. Insert and then remove a servo
mounting screw into each hole. Put a drop of thin CA into
each hole to harden the threads.
