Great Planes Kunai 1.4M EP Rx-R - GPMA1816 - Manual (Page 3)

3
For spoilerons, two 3” [75mm] servo extensions will be required
(then the aileron servos can be connected into separate
channels and mixed electronically through programmable
mixing in your transmitter).
Servos in the 9g range up to 11mm in width are recommended
(to fi t under the aileron hatch covers the best), but servos
up to 12mm in width are suitable. Futaba S3157 or S3117
servos are recommended for the ARF, but the Rx-R includes
factory-installed servos with specifi cations similar to Tactic
TSX5 servos.
Fuselage space in the Kunai is limited, yet there are still
several battery options from 850mAh up to 1300mAh. Each
has obvious tradeoffs of weight and fl ying time. The thinner
profi le of the 1200mAh (shown) fi ts best and the 1000mAh
is a close second.
Tools and Building Supplies
Little in the way of tools and adhesives is required to prep the
Kunai. 30-minute epoxy is recommended for gluing the tail
surfaces and the wing halves together and thin or medium
CA for the rest. Zap Goo (or similar) is strongly recommended
for gluing in the aileron servos because it is secure, yet the
servos may be extracted if ever necessary. More about gluing
in the servos on page 6.

❍ Optional: Du-Bro 1/8" [3mm] double-sided foam
mounting tape (DUBQ3551 for attaching ESC)
Please do yourself a favor: If you don’t already have one,
purchase a quality, machined, 1.5mm Allen hex driver such as
a Duratrax Ultimate Hex Driver (DTXR0288). Lesser-quality
hex drivers end up stripping out the set screws in the propeller
hub resulting in an unsecure propeller or a hub and motor
that will be diffi cult to remove from the airplane.
