Chapter 9, Motor Installation

OXY 3 POWER SYSTEM AND HEAD SPEED SET-UP
In order to choose the best setup for your Oxy 3, and optimize performance, is important know some basic information:
1- Motor Kv –the standard motor is the EOX 2214 –4100 KV
2- Battery Pack –(3s or 4s)
3- Your target head speed
If you use a head speed calculator, use 140T for the main gear and one of the available pinions 10T –11T –12T –13T –14T –15T.
The kit comes with two pinions (11T and 14T) which enables a wide head speed range with both 3 and 4s batteries for novice
and expert pilots.
Oxy 3 gear ratio chart
Oxy 3 Fly Style / Head Speed / Main Blade / Tail Blade / Max Pitch suggestion chart:
Head Speed Note: Although Oxy 3 can handle very high Head Speed, we suggest don’t exceed 4500 RPM to maintain a good
compromise btw performances and efficiency.
Configuration examples
Since the Oxy 3 is a high performance 3D RC helicopter, we suggest using high quality power components including motor, battery and
ESC. Remember the Oxy 3 is a 300 class heli –use light components to maximize flight time and performance.
Here are some suggestions:
-Motor: Suggested KV 3000KV to 4500KV, 21-08 to 22-14 caliber series (stator diameter –stator length).
-Battery: 3 or 4S with capacity from 1300 to 1500mAh / 35C discharge rate. Maximum size: length 76mm, height 35mm, width
37mm, weight 180g.
-ESC: 35 to 40A –with BEC 6V or higher. Or use an external 5A BEC. The Oxy 3 Kit 002 comes with a 40A ESC, preset with 6V BEC
and settings for the EOX 2214-4100KV motor.
-Cyclic servos: Standard MICRO size servo with metal gear –speed: =>0.06 sec/60 at 6V.
-Rudder servo: Standard MICRO size servo –speed =>0.06 sec/60 at 6V –a specific rudder servo is suggested for best tail
authority.
-FBL system: The Oxy 3 was designed around the Ikon / Brain and Mini V-Bar Systems. But many other good quality FBL systems
can be used, depending on your personal choice.
-Main blade: The Oxy 3 can fly with plastic or CF main blades from 245 to 255mm. Our testing was with Lynx 245mm plastic main
blades, and Zeal 250mm and 255mm CF main blades. The Oxy 3 main grips use M2 clamp screw and have a 5.6mm root.
-Tail blades: The Oxy 3 uses our own OEM tail blades, either 47 or 50mm (included with the kit). They use a M2 clamp screw and
3.5 root.
We offer 47 and 50mm tail blades to suit different head speeds. Use 50mm tail blades when your head speed is lower than
3500rpm and 47mm with higher head speeds.
