Heli-Max HMXM1500 - Manual (Page 4)

Mount The Magnets And Sensor
❏
1. Determine where you will mount the magnets and sensor.
The magnets must be mounted where they will turn the same
rpm as the main rotor. We recommend you mount them to the
main gear.
❏
2. Use the template included to accurately mark your main
gear where each magnet will be positioned. Make sure you
count the same number of gradations along each 120° line so
the magnets are aligned. This is important for the sensor to
read them correctly and for balance!
❏
3. Mount the magnets in or on the main gear (with the active
side facing the sensor). They must pass within 2mm of the
sensor. You may mount the magnets to the surface of the gear
with silicone cement, epoxy or CA. For the most security, we
recommend drilling a 3/16" diameter shallow cavity or a hole all
the way through the gear to hold the magnets.
❏
4. Mount the sensor. If possible, mount it directly to the
frame of the helicopter, or fashion a mount from thin plastic or
aluminum. Mount the sensor mount to the frame of your
helicopter where the sensor will be within 2mm or less of the
magnets when they pass.
❏
5. Make certain the sensor and none of the cords can
interfere or become entangled in the mechanics of the
helicopter.
TEST FLYING
Start your engine with the throttle stick at idle and your rpm dial
or switch on the low rpm setting. The governor will not be
activated until the throttle stick reaches the required position
(noted in step 17 under Set Up And Test The Governor) and
you advance the rpm dial (or adjust the ATV if you are using a
two position switch).
When you are ready to lift off, advance the throttle to begin the
rotor head turning, then turn on the governor by adjusting the
dial (or adjusting the ATV) until the desired rotor rpm is
reached. There will be a slight delay when you change the rpm.
Important: Be certain the jumpers are secure on the governor
unit. If the servo reverse jumper becomes disconnected, the
governor will switch off.
Initially, your helicopter will feel different. But, after you get the
feel for the new setup you will wonder how you did without it!
You can get the maximum from your rotor speed governor (and
your helicopter) if you experiment with different rotor rpm. This
way, you can match your helicopter to your engine. Once you
have mastered the setup of your rotor speed governor, your
flying sessions will become more relaxed. Gone will be the
days of programming rotor blade pitch and throttle curves! This
leaves you to the most important task at hand—flying!
