OXY 5 - FLY STYLE / HEAD / TAIL SETTINGS
In order to choose the best setup for your OXY 5, and optimize performance, it is important to know some basic information:
1- Battery Pack you intent to use - (from 6S to 12S)
2- The Motor Kv - See your motor specifications.
3- Your target head speed, If you use a head speed calculator, use 110 Teeth for the main gear and one of the available pinions.
Or use this simple formula:
If you use governor, in order to assure that RPM will be constant during the fly, set a gear ratio to have theory Maximum RPM approximately 10% higher than you’re expected governed RPM.
Your TX Throttle value should be set between 75 to 85%
Example: Target RPM Governed at 80% throttle value = 2000, theory Max RPM should be approx. 2200.
This formula and value can be affected by many factors such: Battery quality, Battery C Rate, Motor Power and Fly Style.
In any case can give you basic information choosing your Motor KV and Pinion (Gear Ratio).
Table below will give you basic suggestion about RPM and Tail Setting (tail pulley / tail ratio) in order to guide on your OXY 5 Fly Style needs.
OXY 5 - ELECTRONICS AND POWER SUGGESTIONS
Head Speed Note: Although OXY 5 can handle very high Head Speed, we suggest not to exceed the maximum RPM on the table above, to maintain a good compromise between performances and efficiency.
Tail Settings, see above Info and Table: “Fly Style - Head - Tail Settings”
CONFIGURATION EXAMPLES:
Since the OXY 5 is a high performance 3D RC helicopter, we suggest using high quality electronics and power components including Servos, FBL , Motor, Battery and ESC.OXY 5 from box is designed to use Cyclic
Standard Size Servo and Rudder Standard or Mini Size Servo, however thanks a simple optional bracket system can use Cyclic Mini Size Servo. From our test we can suggest Cyclic Mini Size Servos for Main Blade
from 500 to 560 and Standard Servo Size from 550 to 570, in any case is hard for us give a precise direction, because in the end we don’t know your personal fly performance. In any case our basic direction cannot
be wrong.Remember that OXY 5 like any other top performance Heli require light components to maximize flight time and performance. Always consider the acceleration G force in fly, few extra gram can become Kg
during some maneuvers, compromising the best performance. Always choose the electronics and the power system suitable for your fly style, “more is not always better”!
remove table and add capital note : Fly Style - Head - Tail Settings Table - Working Process -Coming Soon

Chapter 5: Pinion Selection & RPM
FROM OUR TEST HERE OUR ELECTRONICS SUGGESTIONS:
CYCLIC SERVO: (Standard Kit) : Standard HELI Size Servo– With Optional Mini Servo Bracket: Mini HELI Size Servo.
RUDDER SERVO: Standard or Mini HELI Size Servo, narrow pulse and fast throw – (Suggested Specific Rudder Servos)
BATTERY: Hard to list here all the option OXY 5 gives, however if 6S from 3500 up 5500 and if 12S from 2500 up 4000. For more information about maximum battery size, please check
User Manual Page 2.
ESC: 100 to 150A
MOTOR: 4015, 4020, 4025 , 4035, 4225 - 500 / 1200 KV depending on your Battery Set-Up.
FBL System: The OXY 5 is designed around the Ikon / Brain and Neo V-Bar Systems. Many other FBL systems can be used, depending on your personal choice. Boom Clamp Bottom
Side can accept any of the current FBL available.
MAIN BLADE: OXY 5 can spin 500 up to 575mm Main Blade, 4mm Screw 10 or 12mm Root.
TAIL BLADE: OXY 5 can spin 85 up to 105mm Tail Blade, 3mm Screw 4mm Root.

Fine Adjust Shims Note :
In order to give fine adjustment options,
in the Extra Hardware Bag you will find
extra shims 6X8X0.1.
Start assembly WITHOUT any
shims. If Tail Shaft has sideways play
more than 0.2mm,
add shims as required, to one side, as shown.
PRO TIPS: For best Tail performances little
side play is recommended.
Note: all screws in this step
need loctite during assembly.
before install any shim
read carefully fine

TAIL BELT ASSEMBLY AND DIRECTION CHECK:
In order to check correct belt install,
move belt position A counter clockwise and
the position B must rotate counter clockwise.
Before next step Tail Assembly check carefully
if Belt is installed per need.
Belt MUST move without any friction.
Step 5-1:
Tail belt is showed straight coming out,
from tail boom. Be careful to
check the belt if not twisted inside the boom.
Use a flashlight to check inside the boom, for better vision.
Rotate the belt 90 degrees CCW as shown.
