PNP Receiver Selection and Installation
The Spektrum AR631 receiver is recommended for this airplane. If you choose
to install another receiver, ensure that it is at least a 5-channel full range
(sport) receiver. Refer to your receiver manual for correct installation and
operation instructions.
Installation
(AR631 shown)
1. Remove the canopy from the fuselage.
2. Mount the receiver parallel to the length of the fuselage as shown. Use
double-sided servo tape.
CAUTION:
Incorrect installation of the receiver could cause a crash.
3. Attach the appropriate control surfaces to the their respective ports on the
receiver using the chart in the illustration.
