Heli-Max HMXE0205 - Manual (Page 3)

Gyro Recommendation
We recommend the use of a heading-hold gyro with this
helicopter. The Futaba GY240 gyro (FUTM0809) is an
excellent choice.
Battery
The MX400 Pro requires a 1200-2000 mAh 3-cell Lithium-
Polymer (LiPo) battery capable of delivering 15A of current
continuously. We recommend the ElectriFly
™ 3S 1250 mAh
pack (GPMP0823). This battery will deliver approximately 7
minutes of flight time with the recommended motor and
speed control.
Motor
You will need a brushless motor capable of handling 15A of
continuous current, and up to 22A in bursts. The motor
should also have a kV rating of 2500-3000 RPM/V for use
with the included pinion. We have included the Heli-Max
6-pole brushless motor (HMXG1001) in this kit.
Speed Control
A 25-Amp or better brushless electronic speed control
(ESC) is required for this helicopter. We have included the
Heli-Max 25A Brushless ESC (HMXM3000) in this kit.
Charger
A charger capable of charging 3-cell (11.1V) LiPo batteries
such as the ElectriFly PolyCharge 1-3-cell LiPo charger
(GPMM3010) must be used. If using another charger, it
must be a LiPo charger or have a LiPo charge mode. Never
charge LiPo batteries with chargers not intended for LiPo
batteries or chargers on NiMH or NiCd settings.
Overcharging or explosion may result. In addition to the
PolyCharge, the ElectriFly Triton
™ (GPMM3150) and Accu-
Cycle Elite ™ (HCAP0280) are also suitable chargers.
Battery Charging Leads
Many chargers (including the Triton and Accu-Cycle Elite
listed above) do not include charging leads, but rather have
banana jacks to plug the leads into. If this is the case with
your charger, you will need to purchase a charge lead to
match your battery. For the recommended 1250 mAh pack,
the correct lead is GPMM3105.
❏
1. Remove the fin from the tail gearcase. Apply the
decals to the fin and reinstall it.
❏
2. Apply the decals to the horizontal stabilizer. Install it
and the horizontal stabilizer bracket onto the tail boom with
two 2x8 mm machine screws. Do not fully tighten the screws
at this time.
ASSEMBLE THE TAIL
IMPORTANT!
INSPECT YOUR HELICOPTER
Check all screws on the helicopter for tightness. If any
screws are loose, tighten them before flying. If any
machine screw that threads into a metal part is loose, be
sure to secure it with a drop of threadlocking compound.
This check should include the tail blade grip screws,
which will require removal of the tail rotor blades.
