'''Only researched'''
The T-Rex 450 series is a micro helicopter, slightly larger than the King 2. All carbon frame and metal head and tail parts. The second revisions improved the central shaft, bearings, and some minor details. The 450 series has evolved and improved based on the parent model.

== T-Rex 250 ==
[[Image:Trex-600-500-450-250.jpg|thumb|T-Rex 600 - 500 - 450 - 250]]
This is a new 200 series micro-helicopter from Align, announced in late 2008. Engineered to the quality expected for a T-Rex. There were a few initial problems with the tail but it was quickly handled and fix with a new metal replacement.
The build requires extra attention to details and precision when setting up the links, angles, aligning, and leveling due to the small scale of the helicopter.
=== My Kit ===
* T-Rex 250 Super Combo
** Updated tail grip, 1 bearing (instead of 2)
** CF frame 1.2 mm (instead of 1.0 mm
** Hex screws 0.9 mm (still old, newer models have 1.3 mm)
* Spektrum DX7 heli transmitter
* Spektrum AR6100e 6 channel micro-receiver
* Outrage and Thunder Power batteries

=== Things to note ===
* ESC comes with JST plug for the battery, maybe change to a higher rated 50A Deans connector for less heat, larger connector surface
* Add a piece of zip tie between the tailboom pushrod to secure
* Threadlock to all metal-to-metal screws, only a slight drop on the tip of the screw
* Use purple threadlock on most high-service areas and blue threadlock on other essential areas (head, engine, tail) or all, green threadlock on outer rim of bearings, red permanent threadlock on really essential areas (not really needed on T-Rex)
* Use CA super glue for all metal-to-plastic screws
* Add silicone shock oil to the belt to ease and smoothen the movement, eliminates build-up of static electricity
* Silicon spray for the belt, TriFlow oil for shafts/bushings, White lithium grease for servos, General grease for bearings [http://www.slyster.com/heli/b400bible.html]
* Only use petroleum oil on metal-to-metal parts, most plastic types will weaken when exposed
* When threading the ball links, plier on the link and turn the plastic link
* If servo head is not aligning horizontal as expected, turn it 180 degrees
* Mount battery with connector cables sticking out towards the rotor shaft
* Leave enought space between pinion and main gear that a piece of paper could pass through
* Don't use trim on the trail rotor pitch, confuses the gyro
* Make sure no servo linkage is binding to avoid servo tear/heat-up [http://www.rcgroups.com/forums/showthread.php?t=947539&page=11#post10968352]
* Avoid binding by moving link rod a hole further in, less travel range
* The balance wire on some batteries can break, put the balance wire along-side the battery with a piece of tape [http://www.rcgroups.com/forums/showthread.php?t=947539&page=12#post10973363]
* Fly a few times to break in the heli, especially the links, less twitchy
* Keep the ESC away from the gyro and possibly also the transmitter to minimize interference, 3-5 cm [http://www.rcgroups.com/forums/showthread.php?t=947539&page=13#post10978485]
* Also keep the servo and gyro signal wires away from the ESC and engine power wires [http://www.rcgroups.com/forums/showthread.php?t=947539&page=14#post11007353]
* Use the outter-most hole on the longest servo arm for the swash-servos, links rods perpendicular to the horn [http://www.rcgroups.com/forums/showthread.php?t=947539&page=13#post10979473]
* Although ESC is pre-programmed, do the setup to make sure the throttle range matches transmitter and any problems during manufacturing [http://www.rcgroups.com/forums/showthread.php?t=947539&page=13#post10979505]
* A good battery pack has the ability to hold voltage under load, some battery pack will drop voltage, resulting in bogging of head speed [http://www.rcgroups.com/forums/showthread.php?t=947539&page=27#post11288811]
* Be careful when removing the battery from the velco to avoid cracking the battery mount [http://www.rcgroups.com/forums/showthread.php?t=947539&page=29#post11603795]
* Most usual crash repair parts to get: main shafts, feathering spindles, blades, skids, flybar, tail belt, and ball links [http://www.rcgroups.com/forums/showthread.php?t=947539&page=31] [http://www.align.com.tw/shop/index.php?cPath=22_72_97] (left side, down)
* Broken engine can cause ESC to die, check all 3 engine wires using ohm-meter, great variety between each wire indicates defect engine [http://www.rcgroups.com/forums/showthread.php?t=947539&page=31#post11657790]
* Always put on the ball links with the same orientation, the side with the text pointing outwards
* When adjusting link length, only do full turns, no half turns, the link head has different sides and construction
* Use 3S (series) batteries, 2S batteries doesn't have enough punch for proper headspeed
* Try 0-100-100-100 throttle in normal mode when regular hovering is problematic
* Solder Deans female connector on battery, male on speed controller
* During gyro initialization, keep the heli still and no transmitter stick input

Latest revision as of 23:04, 2 March 2014

Electronic RC helicopters are simpler and easier to maintain than their nitro counterpart. Less parts also means makes it possible to make smaller scale models. Battery longevity has never been better with the latest Lithium Polymer (LiPo) technology.
