Tron Helicopters NiTron 600 Nitro Helicopter Kit

The Nitron 5.5N from Tron Helicopters is a modern design that meets not only high performance goals the market demands, but unique and elegant aesthetics. It's lightweight design, of 1730 grams (3.81lbs), aids in reducing disc loading and helping reduce crash costs by eliminating heavy elements such as boom supports from a conventional design. While light and nimble, the 5.5N is also incredibly robust and stiff, providing pilots with a responsive model that can handle any maneuver with ease.
Overall the frame of the 5.5 is expertly thought out in regards to not only servo geometry, but wire routing as well. Simple cable routing with various options found in the design of the frames offers pilots a clean looking installation thanks to it's modern and functional design. Depending on build preferences the Nitron 5.5 can be equipped with full size servos (by default), or with mini servos.
The Nitron can be built as a 550 or 600 class helicopter, and it's performance will leave you wanting to fly tank after tank. By default with the 21T pinion, it's suggested to pair this model with 580-610mm main blades. An optional pinion of 24T would be needed to fly the model as a 550 size, and of course, pair it with a set of 550-560mm main blades. Keeping an eye on things in flight couldn't be easier either, thanks to it's high visibility canopies offered. Kits are offered with orange canopies, and pilots can purchase either green or yellow canopies as well to meet their preference on color and style.
