The 5.5E 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 1315 grams (2.89lbs), 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 5.5E is also incredibly robust and stiff, providing pilots with a responsive model that can handle any maneuver with ease.

With a wide array of electronic choices, the 5.5E easily fits them all. Motors that are sized in 3225, 4020, or 4025 series will fit, and can accept ranges of 1000-1350kV thanks to it's plethora of gearing options. Both 5mm and 6mm motor shafts are supported, so regardless if you are re-using a motor, or installing a new one, there is a pinion available to match any motor choice. Commonly, a 6s class battery between 5000-5500mAh is recommended, but for pilots looking for pure performance, the tron is ready for 8, 10, or even 12s, and offer the needed optional gearing and frame spacers to accommodate even the largest of batteries. With the ability to house such sheer power, special design was focused on the gearing, and the motor pinion is supported with a bearing to aid in reduction of wear and consistent mesh performance.

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. Additionally, Tron 5.5E accepts both full size and mini size tail servos, allowing you to use anything available on the market within this class.

Built as a 550 class helicopter, it's performance will leave you wanting to fly battery after battery. 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.

Tron Helicopters Tron 5.5E 550 Electric Helicopter Kit
Kit went together perfectly with no issues at all and it is exceptionally well made. Only have about 4 flights on it so far so I can not comment quite yet on its performance but so far I am really enjoying it. The quality of the kit has me looking at the Tron 7.0 and Tron 7.0 Dnamic.

Absolutely fantastic helicopter. I have ALL brands and this is the only one that rivaled and ever-so-slightly surpassed the parts quality of my beloved SAB kits.

They fly excellent, so much that I call it little demon. People know I ABUSE my helis so I have to be careful what I chose to fly so it won't explode in the air and this thing handled everything I threw at it.

I chose the Fusion colors to make it even more attractive.

Buy it with confidence. Amain has always been top notch when it comes to supporting what they carry.

Tron Helicopters Tron 5.5E 550 Electric Helicopter Kit
Amazing Helicopter! Incredibly smooth and quiet, flies like its on rails. Great design that's super easy to work on, everything is easily accessible without the need to disassemble many parts, e.g. Servos, Motor, belt, all easily replaceable. The battery tray system is the best I have ever seen, the aluminum rails make the tray slide in and out very smoothly and the latching mechanism is flawless. Also wiring this model is a breeze and really easy to make it very neat for those who OCD over these things as I do! Tron have built a winner here. My slight negative would be on the manual. Its absolutely fine for an experienced builder, but I felt that it could have been better and easier to follow.
