Rebel MAX + Rebel PRO
Short Manual
This is a short manual to give you the important specs you need to set up your Rebel MAX and
Rebel PRO. The high prefabrication renders a lot of "instruction manual" text obsolete, but some
items have caused confusion and additional questions, so this manual should get you quickly up
to speed with short but important information.
Aileron and flap servos: Install the servos in the servo cutouts of the support ribs. You do not
need more than 30 mm (1 1/4") servo arms(preferrably aluminum arms). Keep the max aileron
throw at 30-35 mm when the servo travels 100%. It is recommended to make a simple long
philips screw driver by cutting one and extending it with a brass tube, so that you can work from
the wing's root. Various servos have slightly different dimensions, some aluminum arms also. In
case your servo arm and the already installed dual control horn isn't lining up 100%, you can work
with a plywood frame or two plywood tabs as spacer between servo and rib.
Note: In the first Rebel PRO we realized too late that the recesses of the servo hatches were not
100% symmetrical and perfectly aligned with the servo ribs. This caused some mis-alignment of
servo arm and slotted hatch. This can be easily fixed by spacing the servo away from the rib with
a plywood frame or two plywood tabs. Just make sure that the servo screws are long enough to
reach the actual servo rib. We are sorry for this mishap, we didn't catch it in time before the first
kits were shipped.
The flap linkage is all internal in the wing, make sure that your flap servo is set so that when flaps
are fully deployed (approx 60 degrees) the servo arm and linkage are IN LINE to each other,
making the servo load free at fully deployed flaps. Please note that you must set and synchronize
the flap down angle with the length of the linkage only, because in that position your servo arm is
fully in-line with the linkage. Servo endpoint setting from the transmitter will not be able to change
the flap-down angle at all.
The wings mount to the fuselage by 4 M6 studs, which also act as anti rotation pins. Use 4 of our
typical M6 knurled plastic nuts. Here, too, we realized after quite some planes delivered that the
hardware bags were short of these nuts. In case you need some, please contact us.
Rudder and elevator servos: These are installed through the root ribs of the respective panels.
Here, too, keep the servo arms short enough so that you can reach max deflection of the control
surface with 100% of the servo travel. Elevator 30-35 mm, rudder 50-60 mm. Especially when
using short servo arms, you will have to extend the slots for the linkages to the rear. That is no
problem and will not cause any strength problems.
Engine, fuel tank and thrust tube installation: The Rebel MAX is designed for 220-260 N
engines, the Rebel PRO will be working well with a 180, and be a rocket ship with a 220. Installing
the engine depends on the engine mount of the respective manufacturers, and also the
positioning of the front end of thrust tube will depend a little on that position. Some
