Radio and Control Linkage Setup For Raptor 50
The performance of any RC helicopter and how well it flies depends strongly on how well the model has
been set up. We will go through step-by-step on how to set up the transmitter and mechanics linkages to
make your Raptor 50 fly at its best. Before you start, please set up the length of all the pushrods
according to the recommended lengths given in our 3D setup drawing in the instruction manual. The
pushrod lengths we have provided are valid for beginners to expert 3-D flying. Then, we recommend
using the reset function of your transmitter to reset all settings to factory default values. Check the end
point adjustment, or ATV value, on your transmitter to make sure the values are at 100%. Next we
recommend to program the numerical values we have provided in the table for the five points in the
throttle curves and for the collective pitch curves. Now you can proceed to do the mechanical
adjustments. We recommend to leave the transmitter on during the following adjustments.
1.Throttle Adjustment.
The throttle arm on the carburetor should always be parallel to the throttle servo arm. When the throttle
barrel is half open, the throttle arm should be straight down. Leave it at this position. Turn on the
transmitter and leave the throttle in the Normal Throttle Mode. Set the throttle trim to the bottom and set
the throttle stick to the middle. Adjust the throttle pushrod to the correct length. Check the throttle servo
travel direction to confirm moving the throttle stick to the high position will move the throttle arm to the full
open position. Use a medium length servo arm. Pick a hole on the servo arm so that when the throttle
stick is moved to the highest or the lowest position, it will fully open or fully close the throttle arm, and
without binding. Now is the time to use the End Point Adjustment or ATV feature on the transmitter to fine
tune the throttle servo travel to achieve this. Avoid using too large or too small ATV values. The ATV
values should stay between 90% to 100%.
2.Collective Pitch Setup
Collective control makes a helicopter ascend or descend by changing the main rotor blade angle.
Beginners and advanced fliers must attach the collective control pushrod to different locations on the
collective control arm. The difference is that advanced fliers desire more collective travel range, usually
+10 to –10 degrees of blade change range. Beginners only need –2 to +10 degrees of blade change
range. We assume you have programmed in our recommended values from the Table for the throttle and
pitch curves.
Collective Setup for Beginners:
Only the Normal Throttle Model will be used. We recommend using a collective pitch range of –2 to +10
degrees. Move the throttle/collective control stick to the center. Attach the servo arm so the servo arm is
in a horizontal position. The servo output shaft has a spline. Try mounting the servo arm with different
orientation until one of the arms becomes close to horizontal. Attach the steel ball to the collective servo
arm at about 15 mm from the center of the servo arm. Move the throttle stick to the middle position. Tilt
the collective control arm/tray assembly so it is approximately in the middle of its allowable mechanics
tilting range. Use the molded pitch scale on the left side of the plastic frame. The pointer on the collective
arm should point to the mark for the hover position. See our drawings of the molded scale in the other
section of this manual. Attach the pushrod. The pushrod length should be 51 mm as recommended in the
drawing. Use a pitch gauge to check the blade angle, it should be around 5.5 degrees. This is what you
need for hovering. This gives a hovering rpm around 1500.
