THE PROJECT

Goblin System:

is the concept on which the project is based GOBLIN.

The basic idea is to compose the helicopter with autonomous functional modules and compact.
The benefits sought are rationality, simplicity, maintainability and transversality in various projects.

The analysis has led to divide the helicopter into three modules.

Form transmission and control (patented)
Module support and cart batteries
Form tail (Patented)

The module and control transmission is made ​​primarily from aluminum frame single indestructiblethey power all the major components such as helicopter servos, engine, transmission, FBL sensor, and interface for the tail pipe.The stiffness of the system is ensured by a single component and not by a set of details.By careful study we used a FEM analysis software.

The media module battery and trolley is made ​​from two sides along with some carbon transverse realize the battery support, regulatory support and support truck.They are all components that do not need to be set and adjusted, in respect of any crash will be much easier their replacement.
The batteries were placed as high as possible to optimize the center of gravity.

The module Queue has as an innovative element to the tube instead of a round tube is a tubular carbon print.
This is joined to the main board through a system of aluminum V-shaped interlocking screws and nylon.
In the event of a fall nylon screws are a major point of collapse.
The tube then has the possibility of facilitating off limiting the damage.
The replacement is then very quickly seen as the solution to the self-centering snap-V .
The choice of molded carbon fiber tube is motivated by the search for maximum stiffness and the choice to take the belt pulleys of large diameter tail.
The cost of the pipe so produced is less than the cost of the whole tube / rods tail / shaft drive

Transmission

Transmitting the power of the current electric motors, define a characteristic sound is not vibrant, compact and above all seek a solution looking for a complex effective transmission with the minimum number of pieces ….

To greatly reduce the noise, to have a great range of possible relationships and we have designed a compact transmission in two stages, primary stage, where there’s speed has been realized belt, where there’s a couple to the secondary helical gears.
The result is a compact module, with a considerable range of possible ratios, quiet and able to withstand large power.
Queued for transmission maximum simplification of the search led us to the belt; modern belts used as the manuals prescribe simply can meet your needs.
We used belts PowerGrip ® GT3 parabolic profile with teeth wrapped in large-diameter pulleys.
We then chose to use a pulley to tension variable that has two tasks: to inform the proper belt tension and cancel the vibrations that are generated on the branch drain.

Other Features

The Goblin System allows significant weight savings.
The value of 3160 [g] is obtained despite the sizing done on trees, on the plate, the motor mount, etc. … hands on.

The control section of ‘helicopter is collected at the top / back, and this optimizes the wiring.Only the speed control has been inserted in the front to reduce the length of power cables and to optimize cooling.

The drive system of the dish is made in an innovative way by seeking the utmost simplicity and rationality.
The rods also have the opportunity to be regulated through a system of thread left / right resolution continues.

Your Cart is achieved through two simple sheets of carbon.

The design is optimized towards the elements that are more involved in the crash phase.
Main shaft, belt tail, servants, carriage, tail pipe …..these have been given the ease of disassembly / reassembly, all the screws are easily accessible and comfortable.

Where are the most frequent interventions (tension, adjustments) have been adopted solutions with self-locking nuts to avoid pre-stuck to the mandatory use Loctite.

Key Features

 

 

The first in T-Rex line to incorporate fully programmable rotor head, providing 3 positive/negative deltas and numerous Bell & Hiller mixing ratios. In addition to the numerous flybar ratios and two types of head dampeners (soft/hard), the flybar paddle weight can also be adjusted to achieve extremely flexibility in flight characteristic tuning. Pilot can program the head for superior stability suitable for F3C competition, or lightening fast agility for 3D aerobatic exhibition. Furthermore, the head rigidity has been improved even further, and specially treated for an extraordinary appearance.

 

The frame utilizes 2mm carbon fiber plates of the highest spec. Patented composite material construction technique cleverly mounts the servos at correct geometry angles and CG adjustable fast-dissemble battery mount without the use of locking nuts. The efficient use of frame space not only improved overall rigidity, but also created a minimalist appearance. In addition, four reinforcement plates are strategically placed at the canopy mounting points to minimize crash damage.

 

 

 

Utilize direct link CCPM swashplate control system to enable direct and fast control response. Specially designed anodized CNC servo horns are not only visually pleasing, but are extremely rigid to prevent warpage issues.
All aluminum elevator servo mount and all aluminum elevator control A-arm assembly eliminate the need for upgrades.

 

 

 

 

Light H-shaped equipment mounting platform with dedicated gyro mount provide large mounting space for equipment mounting flexibility, resulting in a clean layout of your electronics that is easily achievable.

Inspired by T-Rex 700’s battery rail mounting system, this improved version utilizes dual rails, along with a spring loaded locking mechanism to achieve the ultimate combination. Battery tray is locked by a clicking latch, without the use of retaining Velcro straps. A simple push of the release button will eject the battery tray, allowing battery to be pulled out easily.

Suitable battery voltage is 12S lipo at 44.4 volts (two 6s 22.2V lipo batteries connected in series), with capacity in the range of 2600mAh to 4600mAh. Battery sizes can be 43x143x33mm（2600mAh）, 43x143x40mm（3300mAh）, or 44x168x50mm（4600mAh）. Approximate flight time range between 4 to 6 minutes of 3D, or 8 to 12 minutes of normal flying. However, after extensive testing, batteries with capacity of 3300 mAh yield the most optimal power to weight ratio.

A brand new 600 class high voltage 12S motor, paired with the result of Align’s extensive test for most optimal gear ratio, provides explosive power output. The grea ration is changed from MOD0.6 into MOD 0.8 to increase its strength for gear strips. Correctly tuned tail gear ratio ensures tail rotor speed is maintained within proper range, eliminating any overspeed induced tail vibration found in other helicopters, and providing the most effective tail locking efficiency. Due to the increased in power output, main gear utilizes module 1 gear pitch found in 700 class helicopters. In addition, helical gear design effectively minimize power loss and reduce noise. A third motor bearing block ensures consistent gear mesh, and eliminates stripped gear caused by gear mesh variations from gear warpage.

 

 

Additional radial bearing is added to the top of the main gear hub to ensure stable rotation. This improves and eliminate jammed one way bearing in the condition of high power in high speed.

Trex 550E and 600E are suitable to upgrade with MOD 0.8 tail drive gear assembly.

 

 

 

High quality 5mm carbon rod is used for rudder pushrod to minimize the effect of vibration on rudder. Not only does this increases the helicopter’s rudder locking efficiency, but it also effectively improves the rudder control feel.

 

 

 

 

Brand new CNC machined metal tail gear box, with thicker side plates to increase rigidity. The more streamlined design also allows for simpler disassembly. Tail pitch slider features wider span to make the tail moves more precisely, with larger diameter slider to improve positive sliding action and durability. Tail pitch bell crank socket contains embedded Teflon sleeve, and features a shorter distance between bellcrank and pitch slider for reduced leverage distance. These factors all contributes to increased smoothness in tail pitch sliding action, minimize interference. From our long time testing, the result show this is effectively increase longevity and the new tail control linkage rod minimizes deadband and improves control precision.

We have also improve the tail rudder control set of Trex 600E PRO to increase longevity and minimized deadband.
