Align TB70 RC Helicopter - Modern High Performance

The Align TB70 helicopter is a modern take on the familiar TRex helicopter lineup that have been a top choice for pilots of all skill levels. Unlike historical versions of their 700 size rc helis, the Align TB70 remote control heli features a host of new design features. With three different versions to pick from, the Align TB70 heli can provide you with nearly all the essentials you need, or allow you to outfit the model with your own hand picked electronics to suit your preferences. 

One of the most unique design differences is the belt driven tail and motor gear train, which provide pilots with simple adjustments and ease of maintenance for the entire drive system. The drive system is housed inside of the main frame, which are composed of a 2mm thick upper frame, and 3.5mm thick lower frame. 

The upper frame has a lot of space for electronics, and keeping your wires tied up nicely, so everything is neat and easy to access. The cyclic servos are horizontally mounted, and provide great geometry due to their symmetrical mounting. The lower frames feature a POM white plastic that surround the outer edge of the frame, and feature Align TB70 branding to not only stand out on the bench, but add increased visibility in flight in areas that normally aren't easily visible.

Depending on the kit you choose, the TB70 heli will come with either an Orange and Yellow painted canopy, or Blue and Yellow canopy. Both options are highly visible, and are light weight in design, weighing on average about 120g. The canopies are attached to the frame with a button style mount, that is not only fast to take on and off, but very secure. 

The Align TB70 also features an EFL style rotor head. This lightweight design aids in lowering the CG of the TB70 helicopter, adding to improved response for all flying styles. The main shaft is secured to the frame via three bearing blocks, providing increased strength and stability of the rotor head in a large range of head speeds. 

The tail system features several features that make owning a tail belt driven heli simple. Tail belt tension can be adjusted by adjusting two rear facing screws at the end of the rear tail boom clamp. This, paired with an adjustable tail belt tensioning system, makes it easy for pilots to find their desired belt tension with ease. The tail box features a lightweight design, that is strong, yet simple to service.

Finally, the battery tray system is linked to the upper main frames. The POM plastic rail system allows for the battery tray to slide in and out easily. In addition to the tray system, a security quick release latch system is in place to ensure that not only swapping batteries is fast, but secure for any style of flying.
