Optional Brushless Main Motor Power System Installation and Setup
The Blade CP Pro 2’ PNPs separate Spektrum AR6100 receiver and 2-in-1 control unit allow you the option
of upgrading to a brushless main motor power system, without the need for difficult modifications or a new
radio system . An optional brushless main motor power system can provide added power and/or duration when
compared to the stock brushed main motor power system, and is an excellent choice for those interested in
maximizing the performance and aerobatic potential of their model .
We have tested a wide variety of motor types, in a wide range of Kv (rpm/v) values, and gear ratio combinations
in the Blade CP Pro . While many combinations offered a noticeable improvement in power or duration when
compared to the stock brushed motor, we found the following recommended power system combination (and
required supporting accessories) to provide the best balance of power and good flight duration when using the
included 3S 11 .1V 800mAh Li-Po battery pack:
Item Description
EFLA228 JST Female/2 JST Male Parallel Y-Harness
EFLA311B 20-Amp Brushless ESC
EFLM1000 Park 370 Brushless Inrunner Motor, 4100Kv
EFLM1912 Heat Sink, 20x20mm (optional)
EFLM1949 Pinion Gear, 8T 0 .5 Module 2mm ID
EFLRYH3 3” Y-Harness
NOTE: It is possible to substitute the recommended 8-tooth pinion (EFLM1949) with a 9-tooth pinion (EFLM1950)
for increased power at the expense of slightly reduced flight duration . However, those interested in maximum
power and performance should substitute the 8-tooth pinion with a 10-tooth pinion (EFLM1951), noting that the
typical “aggressive” flight duration will be approximately 5 .0–6 .5 minutes per charge using the stock Li-Po battery .
Also, reduced flying weight and a similar power-to-weight ratio can be achieved by using a Thunder Power Pro Lite
series 3S 11 .1V 730mAh battery (THP7303SJPL), while improved power and duration can be achieved by using
a Pro Lite series 3S 11 .1V 910mAh battery (THP9103SJPL) . However, please note that the stock charger cannot
be used with the 730mAh battery, and that a 3S 11 .1V Thunder Power to E-flite balance connector adapter cable
(included with EFLA229) is necessary to allow use of the stock charger with the 910mAh battery .
The following steps outline installation and setup of the recommended optional brushless power system:
• In order to provide the most secure motor mounting, and proper clearance for the forward bearing cup in the
main frame, it will be necessary to install the Park 370 brushless motor’s (EFLM1000) included “Adapter Ring .”
If, after the first few flights, you would prefer to have even quicker and more aggressive cyclic response, you can
reposition the flybar weights so that they are closer in to the head/main shaft on the flybar . It is usually best to
move the weights in only a small distance at a time before making each subsequent test flight, until you find the
position at which you prefer the cyclic response most .
NOTE: It is important that the weight(s) on each side of the flybar be positioned at a distance equal
from the head/main shaft in order to prevent imbalance that could lead to vibration in the rotor head.
Dampening of the rotor head (main rotor blades) can also be adjusted in order to fine-tune the cyclic response of
your model . In general, stiffer dampening will result in quicker cyclic response . The dampening of your Blade CP
Pro 2 has been set to provide a good balance of cyclic response and stability right out of the box, and we suggest
that you make your first flights with this amount of dampening before making any changes .
If, after the first few flights, you would prefer to have even quicker and more aggressive cyclic response, you
can stiffen the rotor head dampening by adding shims between the o-ring and step washer on each side of the
center hub (see the “Exploded View” drawing and parts listing for reference) . Head dampening shims are available
separately in packs of eight (EFLH1144), however, you should install only one shim per side at a time before
making each subsequent test flight, until you find the dampening at which you prefer the cyclic response (and
stability) most .
NOTE: You must always install an equal number of shims on each side of the center hub.
NOTE: If you install too many shims, and the dampening becomes too stiff, the helicopter can wobble
and shake in flight. Take care when making test flights after adding shims to prevent crashing the
model as a result of a wobble or shake. Typically, we find that using 2–3 shims per side with the
stock high-power 370 brushed main motor works well. More shims per side can cause the wobble
and shake. If running a power system that is capable of producing higher rotor head speeds, like
the optional 370 brushless motor power system, you can sometimes add even more shims before
encountering the wobble and shake. Again, exercise extreme care when test flying the model after
adding shims.
