INTRODUCTION
Congratulations on your purchase of the SIG T-CLIPS 70 EG
ARF. We hope you will enjoy this unique fun scale R/C model.
Assembly of your T-CLIPS 70 is fast and simple when following
the detailed instructions in this manual. We urge you to read this
assembly manual completely before assembly. Familiarize your-
self with the parts and the assembly sequences. The successful
assembly and flying of this airplane is your responsibility. If you
deviate from these instructions, you may wind-up with problems
later on.
Good luck with the T-CLIPS. Let’s get started!
ADDITIONAL ITEMS YOU WILL NEED TO PURCHASE
In addition to this kit, you will need the following items to complete
your T-CLIPS and make it flyable.
❑
RADIO SYSTEM
The T-Clips 70 requires a standard 4-channel radio system and
either four or five standard size servos (four servos is using elec-
tric power, or 5 servos if using glow engine power). "Standard"
size servos typically have 40-60 oz. of torque. In addition, you'll
need two 6"- 12” long Servo Extension Cords and one Y-Harness
Chord for connection of the two aileron servos to the receiver.
(The length of extension cord you will need depends on how long
the wires are coming off your servos. With Hitec® standard ser-
vos we used 6 in. long extension cords. Check your servos and
plan accordingly.)
❑
POWER SYSTEM - GLOW OR ELECTRIC?
The biggest decision you will have to make is whether to power
your T-CLIPS with a glow engine (2-stroke or 4-stroke) or an elec-
tric motor. We have flown the T-CLIPS 70 with a variety of both
types of power systems, and we make the following recommen-
dations based on our successful on-field experience.
GLOW POWER RECOMMENDATIONS
❑
ENGINE
We recommend the following size engines for the T-CLIPS 70.
2-STROKE - .53 to .61 cu. in.
4-STROKE - .53 to .65 cu. in.
Whatever brand engine you choose, take the time to carefully
break it in according to the manufacturer's instructions. A good
running, reliable engine is a minimum requirement for the enjoy-
ment of this or any R/C model aircraft.
❑
PROPELLER FOR GLOW
Refer to the engine manufacturer’s instructions for recommenda-
tions on proper propeller size for their engine. In our experience,
most .60 size 2-stroke glow engines will fly the T-CLIPS 70 very
nicely with a 12x8 or 13-6 prop.
ELECTRIC POWER RECOMMENDATIONS
❑
1200 - 1700 watt BRUSHLESS OUTRUNNER MOTOR
The T-CLIPS 70 is designed to be powered with a 1200 to 1700
watt electric brushless outrunner motor. This size motor is some-
times referred to as a "60" class motor to those who like to make
a comparison to a glow motor. Also, the motor you choose should
be rated at 300-400 kv, in order to turn an appropriate propeller.
Here is are some motor sizes that work well in the T-CLIPS 70:
5030-390
5062-400
5065-400
❑
MOTOR MOUNT
A laser-cut plywood adjustable motor mount is included in this kit.
It should work perfectly for any suitable brushless outrunner motor
which has an “X” or “cross” motor mount plate on the back.
❑
60-75 amp ESC (Electronic Speed Control)
We used the Castle Creations® 75 amp ESC in our T-CLIPS pro-
totypes. This is an excellent "switching type" ESC that has a built-
in BEC (Battery Eliminator Circuit).
Note: BEC allows you to use the same battery pack to power both

What do those numbers mean?
NOTE: This numbering system is very common, however there
are exceptions. For instance, some motor manufacturers will
list the actual diameter of the stator (armature) inside the motor
instead of the case diameter. Some may list the length of the
stator inside the motor instead of the case length. Some will
give you both if you dig far enough into their specs. Make sure
you understand the motor manufacturer’s numbering system
when shopping for a motor.
