Align T-REX 700X Dominator Helicopter Kit
If you fly aggressively enough beware the main shaft will snap in flight. I’ve personally done it 3 times and each time was seriously expensive. I reached out for help from the distributor and Align in Taiwan and was strung along until I gave up. They finally recognized the problem but still offer no solution and still won’t make it right but continue to sell these kits.

Heads up, if your buying this kit version, make sure your using servos with leads long enough. The way you have to route the wires leaves very little room and if you try to add extensions they get in the way of the motor pinion and the main gear. This is the toughest helicopter I ever had to wire. Other then that its a simple build. Built it in a weekend.

A very good bird for the price. Good quality parts and historically good availability and pricing. One thing is that the tail design has a lot more metal bits and pieces than other designs which adds tail weight. The 5-degree forward tilt of the skids is a nice feature but sometimes it messes up the rescue feature of my gyro. Overall I’m pleased with the forward pitch design.

This is a good choice as a first 700-size machine or an everyday driver for a budget flier.
