| 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.

| 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.

| === 250 SE ===
| |
| In late August 2009 Align released the improved T-Rex 250 SE. The main differences are a all shiny silver metal head, rotor holder, improved CCPM plate for better 3D, new bearings in washout and mixer arms minimizes slop, upgraded tail with even more grip weights reduces servo load, exchangeable main gear, new more efficient 250SP motor, new anti-rotation guide, and 1.3 mm headed screws standard. It's a revised T-Rex 250, all the [http://www.align.com.tw/shop/index.php?cPath=22_72_102 new parts] are available as upgrades (29 right now).

| |
| This is a list of possible upgrades, it includes third-part manufacturer parts as well as Align's own upgrades and revised spare parts.
| |
|
| |
| From what I've found the following notation at the end of the Align partnumbers designates the type of change done to the part:
| |
| * '''-1 or 1''' - Minor revision of the part to fix a design flaw or obvious fault, e.g. fixed tail hub bearings, longer tail control arm
| |
| * '''A''' - Upgraded part, offers additional functionality compared to the old part, e.g. 1.3 mm hexagon screws (most parts)
| |
| * '''F''' - Color difference, silver mostly, e.g. new silver parts for 250SE
| |
| * '''Q''' - Metal part, silver mostly, e.g. seesaw holder, head stopper
| |
| * New number - All new part all together, e.g. new exchangeable main gear, metal version of parts

| |
| === 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
| |
| * After extended use replace main shaft head screw, high-speed/stressed bearings, and worn-down parts
| |
| * When changing the pinion, the gyro gain will likely be lower, i.e. 16T 63%, 15T 40% [http://www.rcgroups.com/forums/showthread.php?t=947539&page=120#post13177260]
| |
| * If heli moves to the left or blades are not tracking properly, try measuring the links between swash and seesaw arms, must be 100% identical
| |
|
| |
| === Checklist and maintenance ===
| |
| # Check mixer nuts and bolts in head and tail
| |
| # Inspect screws and alignment of main blades, flybar, and tail blades
| |
| # Move feathering shaft to check dampeners
| |
| # Check all ball links for slop or play
| |
| # Check tail belt tension
| |
| # Fully charged batteries, both heli and radio
| |
| # Radio range check and trim settings
| |
| # Make sure gyro, receiver, and esc is mounted securely
| |
| # Inspect power and servo wiring
| |
| # Perform full cyclic throw on all servos, watch swashplate movement
| |
| # Switch to Normal mode, Throttle-hold on, low throttle stick, then connect power
| |
| # Start a timer to notify when the battery is depleted
| |
