OXY 2 POWER SYSTEM AND HEAD SPEED SET-UP
In order to choose the best setup for your Oxy 2, and optimize performance, it is important to know some basic information:
1- Motor Kv – Min 3600 - Max 6000 - See your motor specification
2- Battery Pack – (3s or 4s)
3- Your target head speed
If you use a head speed calculator, use
110T for the main gear and one of the available pinions 10T – 11T – 12T – 13T – 14T – 16T – 18T .
The kit comes with one pinions (12T-2mm Shaft ) which enables a wide head speed range with 3s batteries and 5500Kv Motor perfect for novice
and expert pilots.
Head Speed Note:
Although Oxy 2 can handle very high Head Speed, we suggest not to exceed 5500 RPM to maintain a good
compromise btw performances and efficiency.
Configuration examples
Since the Oxy2 is a high performance 3D RC helicopter, we suggest using high quality power components including motor, battery and
ESC. Remember the Oxy 2 is a 200 class heli – use light components to maximize flight time and performance.
Here are some suggestions:
-
Motor: Suggested KV 3600KV to 6000KV, 16-11 to 19-12 caliber series (stator diameter – stator length).
-
Battery: 3 or 4S with capacity from 800 to 1000mAh / 45C discharge rate. Maximum size: length 72mm, height 25mm, width
35mm, weight 114g.
-
ESC: 25 to 30A – with BEC 5V or higher.
-
Cyclic servos: Standard Sub MICRO size servo 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 2 was designed around the U-Ikon / U-Brain and Neo V-Bar Systems. But many other smaller size FBL systems
can be used, depending on your personal choice. Max inner Frame dimension 26mm.
-
Main blade: The Oxy 2 can fly with plastic or CF main blades from 190 to 210mm. Our testing was with Lynx 190mm Carbon Plastic main
blades, and Zeal 210mm main blades. The Oxy 2 main grips use M2 clamp screw and have a 3.2 mm root.
-
Tail blades: The Oxy 2 uses our own OEM tail blades, either 38 or 41mm (included with the kit). They use a M1.6 clamp screw and
3 root.
We offer 38 and 41mm tail blades to suit different head speeds. Use 41mm tail blades when your head speed is lower than
4500rpm and 38mm with higher head speeds.
