GT-500E Electronic helicopters assembly flight test comment
In the rapidly economic development and replica popular in China.Some people still persistent to create self-brand's value. [GT-500] which produced by Gootch Model Technology CO.,Ltd. In the leading Aeromodelling competitions in the world, we believe only good quality and better flight function can get approvement from flying friends.
The writer would like to share the process of GT-500's assembly with all of you:
The package for the box and canopy are with bright color , we believe the visual effects should be good! The main frame for GT-500 is constituted by 4upper and lower frames. It is made by precision processed carbon frame which the thickness is 1.6mm. Including Bottom Base and Carbon vertical Stabilizer and Carbon Horizontal Stabilizer which all are made by precision processed carbon frame .
Hollow the size of the steering gear installation location for the market of conventional steering of the installation, allowing the pursuit of performance, like the players till the fever-class selection of high-speed large torque on the steering gear have more choices, I selected the company's S9252 is a FUTABA steering gear;
In the rotor head structure, [GT-500] will be the main rotor holder seat, metal main rotor housing, metal head stopper, metal flybar seesaw holeder, as well as the upper and lower shear-arm parts, as well as control of the puck behind the pitching movement A cross arm and ECCPM disk, etc. are all CNC precision machining aluminum alloy products; all parts has been completely upgraded only regret is that the quality of bearing selection is not very good, in the screws and there is little clearance between the bearings, I replaced the import bearings After the problem has been resolved
GT-500] follows the end of the traditional belt drive transmission mode, the tail of the same all CNC precision machining of aluminum alloy products, the structure is relatively simple, the weight should be lighter; installation of the tail and found the tail shaft sleeve head size is too thin, which require special tools for removal and disassembly process easy to damage the sleeve on the end of the horizontal axis is very sleek, installation, the tail pitch arm movement at the end of the horizontal axis there are too tight on the phenomenon; I will be the end of the pitch change rocker button on the ball with the ball the ball the first hole-reaming tool for the expansion until smooth so far to solve this problem; machine basic installation is complete, the next job is to debug flight;

[GT-500] of the ECCPM the puck through the triangular switching rocker to promote, this way played a significant role in the protection of the server, but the output torque of the speed of the server to be a little bit slow, post-flight will be able to know that it will affect the overall flight performance
Arm hole at a location server to select the most out of all of the holes in order to achieve the fastest response speed of motion effects; and while two pairs of push-pull rod parallel,
Pitch and throttle settings, [GT-500] there is no distribution of the propeller manufacturer, the author made use of high-quality 430mm carbon fiber paddle, where I set the pitch angle of -12 degrees ~ +12 degrees. Throttle setting in, IDLE UP part of a 100%, 90%, 100% of a V-curve, so that motor maintained at the highest speed, there facilitate the implementation of 3D action
Rudder and gyro settings, I just set up in accordance with the normal gyro to set up, and there is not much more difficult, but the server in the rudder arm hole location, the proposed location is 11mm, in theory, If it is not specifically requested, we try not to use the most outside of the hole bit, to avoid the control action which led to the resolution of poor lock ineffective, and certainly can not be used inside the hole, or else the trip is not enough; gyro sensitivity settings approximately 65% of the value (in the FUTABA remote control system set up under the

Flight test
In addition to the flight test [GT-500], 3D performance, but also introduced to the GT's [GT-500] standard configuration of a brushless motor performance test;
Promote the throttle away from pole, brushless motor to start normal; off to stop hanging, feeling relatively quiet and stable, there is no vibration phenomenon, the air hovering a moment, feeling for me for like 3D action in an instant reaction to a little bit Pianman; regardless of the first cut IDLE-UP repeat
Brushless motor power markedly strengthened, first try to do a simple Sustained Inverted Hover (inverted hover), without feeling the loss of power, brushless motors can withstand the test of time in the sense of turning a lot of reactions were mild, To test the brushless motor power, I deliberately wear a rather large power pendulum movement, feeling a little bit ahead of braking point a little in order to control, no obvious shortage of power, after all, is a standard configuration, is said to be original with 3D non-violent escalation of the recommended brush motor launch waiting writer
In conventional selection of FUTABA-S9252 server, the action's accuracy control showing is outstanding , so that dynamic response improvement and almost no error, the whole action are smoothly and gentle; its another enjoyment of 3D flying.
The rubber ring 'hardness for Damper need to strength .In order to improve the sensitivity .it will be better to take imported bearing instead of bearing
