NOTES FOR ASSEMBLY.
This model helicopter has been designed and produced to be a high performance 3D machine. With its simple design and low
parts count, pilots of all skill levels will appreciate its easy repairability. This is not a toy. Please take care assembling the model,
and take care and responsibility when you fly it. We take no responsibility for any damage or injuries, either direct or consequential,
from the use of this product. If you are not experienced in the assembly and flying of a high performance model helicopter we
recommend you seek the assistance of an experienced pilot. Above all, fly safely and we hope you enjoy this model.
Only fly this model in areas designated for the use of model aircraft. Ensure you obtain indemnity insurance, normally available
through your National model aircraft association. Remain at least 6 meters (20 feet) from the model at all times. Never allow
spectators or animals any closer than 30 meters (100 feet) from the model.
Please read this instruction manual fully before beginning assembly of this model helicopter. Be sure to use quality tools during
the assembly process, and remember not to overtighten small fasteners. Note the following symbols which are used in this manual.
Use thread lock sparingly where indicated. If you are unsure about an assembly step, please seek the advice of an experienced
pilot. Warranty on any parts is only applicable prior to assembly of the part on the model.
NONE OF THE PRE ASSEMBLED PARTS HAVE THREAD LOCK ON THE SCREWS. IS IMPORTANT TO READ AND FOLLOW THE ASSEMBLY
NOTES IN EACH STEP. INCORRECT ASSEMBLY OR NOT USING THREAD LOCK WILL CAUSE A CRASH OR INJURY.

Important Note:
Once you finish assembly,
check the system can slide and move without friction.
If tail system is assembled correctly, it should move
smoothly and without play. In case of friction or play
recheck each single component and re-assembly as
required. If necessary adjust the position of the Bell
Crank Arm. A common mistake would be allowing
loctite to contaminate the bushing and plastic in step 2.
Note: Line up

OXY 3 POWER SYSTEM AND HEAD SPEED SET-UP.
In order to choose your best Oxy 3 set up, and optimize performance, it is important to know some important information:
1- Motor Kv - (EOX 2214 - 4100 KV Standard Motor)
2- Battery Pack - (3s or 4s)
3- Your target Head Speed
If you use a head speed calculator that request main gear ratios, use 140 T for the main gear and select one of the pinion available
10T - 11T - 12T - 13T - 14T - 15T - (Standard Kit come with two pinions 11T and 14T, that ensures a Head Speed Range with 3 and 4S suitable
from Novice to Expert Pilot requests.
Oxy 3 available reduction ratios option 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.
