You could use two 4S/4000mAh or above LiPo batteries in series (equal to 8S battery 29.6V)
with our 638109 motor, 100A ESC and an 18x8 or 19x6 propeller for scale-like flying. These
batteries are easy to insert and remove one-by-one through the hatch.
h)
If you want a little more power, you could use a 10S/3900mAh or above LiPo battery, but
you will need to modify the battery compartment and hatch by
trimming the ribs (or removing
them altogether) as shown below
:
If you increase the width of the battery compartment, also increase the width of the battery
hatch opening as follows:
Remove wood from sides. Cut new slots. Add a barbecue-skewer ‘hinge’ at each side.
i)
As shown above, make an opening in the front of the motor
mounting box for the ESC’s battery leads. (NOTE: If you
include the added margin of safety described below in
step 9, we recommend you add the extra wire between the
ESC and the ESC’s spark-prevention connectors to relocate
the anti-spark connectors to the observer’s cockpit.)
4.
Use one of the following two options to secure the motor
mounting box to the fuselage.
Option 1
: Secure supplied pieces of metal L-channel to the
motor mounting box and to the fuselage with wood screws.
(
Advantage
: Easy removal for possible future repairs.
Disadvantage
: Installation is more complicated and is not as
strong nor as permanent as gluing the motor box into the
fuselage.)
Option 2
: Carefully position and permanently secure the motor box into the fuselage with epoxy.
(
Advantage
: Safe, strong and easy to install.
Disadvantage
: Once glued into the fuselage, the
motor mounting box cannot be removed for any possible future adjustments or repairs.)
5.
Depending on your battery’s length, you may add some optional foam rubber (not included) as a
spacer/cushion behind the battery.
6.
Carefully and securely solder all required connectors between your motor, ESC and battery. Use
heat-shrink tubing (not included) to safely insulate all electrical connections.
7.
Use double-sided tape (not included) to secure the ESC behind the motor on an inside wall of the
motor mounting box. Guide the ESC’s servo-type connector straight back and into the cockpit.
