Charging the Receiver Battery
1. Use a charger (we recommend the
SPM9526 Spektrum 150mA wall charger)
to charge the receiver battery. Allow
10–12 hours to fully charge the receiver
battery when it is fully discharged.
2. Once the receiver battery is charged,
place it in the boat.
3. Check the switch harness to make sure
it is in the OFF position. Plug the receiver
battery into the switch harness. Make
sure to match the polarity of the plugs so
the black and red wires align with each
other.
4. Replace the hatch cover.

Transmitter Battery Installation and Checking the Controls
EN
1. Slide the battery cover off in the
directions shown to access the battery
compartment.

transmitter. Make sure to match the
polarity of the batteries to the polarity
molded into the battery compartment
of the radio. Slide the cover back into
position on the radio.
4. Move the stick on the transmitter to
the right. The rear edge of the rudder
will move to the right as shown. Actuate
the STR (steering) reversing switch if the
direction is reversed.
3. Slide the power switch on the
transmitter to the ON position. Move the
receiver switch to the ON position.
Rear Edge
Note: If you find the boat is turning too
quickly, you can reduce the amount of
rudder by adjusting the dual rate knob on
the top of the transmitter.
13
EN
5. With the radio system on, move the
left stick on your transmitter "up" and
manually push the main sail and jib sail
open. You should be able to open the
sails to at least a 60-degree angle. If
you cannot do this, it will be necessary
to adjust the length of the line (allowing
more slack) by adjusting the jib stays
located underneath the main sail and jib
sail booms.
6. Move the left stick of your transmitter
"down" to close the sails. The sails should
close, with the jib sail being tighter than
the main sail. There should be some
slack left in the sail rigging when the sail
gimbal moves the sails in.
14
Sailing Tips
After you have finished rigging the sails, it will be helpful to adjust the sails in order to optimize
the performance of your boat. It is often necessary to briefly sail the Serenity in order to see
how the sails need to be trimmed. Take your time to optimize your sailing pleasure.
1. Check to make sure the main boom
and jib boom are in line with each other.
Adjust the jib stay at the top of the jib
sail to position the jib boom.
