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”!
