Recommend Main Blade Length: 580-610mm

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.

    Last a while. Will be buying more toys soon.
    Color: Consuela the Cactus - Large, Size: Large Dog
    Best dog toy I have ever bought. I have three dogs, two at the time I bought this toy. It took them over a year to break through the first layer. The flower comes off first so be careful your dog doesn't swallow it. It still has the second layer so it still looks like a cactus. No stuffing to clean up when they tear into it, which makes it far less messy than other toys. One of my dogs is obsessed with fetch so I use it like a ball inside. The oval shape makes it hard to ensure when it bounces that it will bounce straight. It's bounced into walls and other stuff that I wasn't intending it to hit. Not much of a squeak so I can let them play with it for hours and I don't get annoyed with the noise. Great toy that lasts a while.

    Nice Value
    Color: Consuela the Cactus - Large, Size: Large Dog
    Very cute! Its soft and feels like it is well made. It is a heavier toy and a tougher one. Not a plush toy. I will order again for our older dogs. Nice value for sure!

    Great toy for our best boys!
    Color: Consuela the Cactus - Large, Size: Large Dog
    You can never go wrong with BarkBox toys and this was no exception. Our dogs like toys that have squeakers and that they can tear into. This style of toy fits the bill. The design is cute as well. I’ve had this in the house for months and, while it’s definitely seen better days, it’s still intact and they haven’t gotten to the inner layer. (Not for want of trying.) The perfect type of toy for our fur babies.

    Survives 7 months so far.
    Color: Christmas Consuela, Size: Large Dog
    It is still intact after nearly 7 months of constant play. My blue heeler normally destroys toys in just a few weeks. Consuela has exceeded expectations of survival with an extremely chewy, destruction prone dog.

    Short-lived but much enjoyed as a chew toy
    Color: Consuela the Cactus - Large, Size: Large Dog
    I bought two of these for my "granddogs" in the size for Large dogs. The German Shepherd-mix stole the one intended for the border collie-mix and had both toys halfway destroyed within a day--I'm pretty sure they didn't survive much longer after that. Much enjoyed! Maybe I should've bought the Extra Large size, because the Large barely fit in her mouth and she wanted to play tug-of-war, so there wasn't much for me to grab onto. Then the border collie wanted in on the action (she's older, so she needed help tugging!) but there wasn't enough material for her to grab onto without accidentally sinking her teeth into me instead.
