Read the manual carefully before you start assembling the T-Rex 250 Kit, which will assure for a much more pleasant building experience. What I like about the T-Rex Super Combo Kit, is that the servo’s, gyro and speed controller is supplied with the kit. All you need to get into the air is a programmable six channel or more transmitter, receiver, dial pitch gauge and a LiPo battery for the helicopter.

A Phillips screw driver, Hexagon screw driver and tweezers are supplied with the kit. Additional tools like scissors, cutting knife, diagonal cutting pliers, needle nose pliers, oil and glue are needed for assembly. The supplied Anaerobics and Thread Lock tubes were already used at the factory when they assembled the rotor head, the main frame and tail rotor assembly. I only used the Thread Lock tube once when the metal pinion gear was fixed to the main motor shaft.

All the assembling steps are numbered in the manual and they correspond to the different bags with parts, which are also numbered. This number system makes it fairly easy not to get confused while building the T-Rex 250. It took me about five hours to complete assembling. The five hours assembly time includes the assembly of the helicopter, installing the servo’s, main motor, gyro, speed controller and receiver.

Take note that Align has provided a small bag with some spare screws and washers in the T-Rex 250 Super Combo Kit. Don’t worry when you are left at the end with this bag after assembly. You haven’t left any screws and washers out….

   •   Make sure the distance between the flybar paddles and flybar control arm are exactly the lengths stipulated in the manual .

   •   Make sure the flybar paddles are perfectly horizontal with the flybar control arm when viewed from the side.

   •   Give the Thread Lock on the pinion gear and main motor shaft to dry properly before operating.

   •   Make sure that the main gear and pinion gear mesh correctly according to the manual.

   •   Make sure that the tail rotor belt is twisted the correct way inside the tail boom.

   •   Make sure that the main rotor blades are balanced. Don’t assume that they are balanced because they are new.

   •   Make use of cable ties to assure that no wires will interfere with moving parts on the helicopter.

   •   Lastly, do an overall check and make sure all screws are tight, and make sure that nothing is out of place.
