Tron Nitron 50 Heritage Helicopter Kit (w/o Blades)

Great quality, lightweight, well thought out and better than the original in every way. Having a hard time deciding between a 580 and 600 size blade? If you’re heavy on the left stick, get the Rotortech 580 Ultimates. If you’re a smoother flyer, a 600 blade will suit you better. The MSComposit Rapid 605’s make the Heli feel nimble and roll/flip fast like it’s running a shorter blade. The build sequence following the manual is weird (like the Nitron 90) and their manuals leave a lot of room for improvement. I don’t like that there isn’t a paper manual book included. Otherwise the build goes ok, just don’t over-tighten any screws that go into the “frame support” pieces (mostly in the front, ahead of the clutch). Do yourself a favor and get the harder (90 shore) O-Rings for the head and install them right from the get go, unless you’re just a sport flyer. The soft o-rings fly fine, but you get a lot softer stops and response from the helicopter. The manual calls for 97mm-107 tail blades, Rotortech Ultimate 96’s work just fine. The superlight canopy and boom paint look great in all skies. Initially, like the Nitron 90, some of the parts kind of feel cheap, but it’s because they’re very light. I know this new model weighs around 59g more than the first version, but the improved and beefed up clutch and stronger parts everywhere are what adds the additional weight. Don’t worry about it, with 600 size blades you won’t feel it. Compared to other 580/600 size nitros, the design is amazing and the quality is better than the XLPower nimbus nitro (that can run 580 blades) a lot lighter than a Trex 600 nitro, but not quite as impressive and simplified as the SAB Raw 580 nitro, but it’s lighter. Overall, killer looks and performance and a lot of upgrades that carried over from the BK Edition Nitron 90. Smooth helicopter. If they would include a manual, de-burr the carbon a little better, and make those frame support pieces feel a little nicer, include a paper manual and the 90 shore head dampeners, the value would be even better. When they go on sale, don’t pass it up!!

Let’s start out by inboxing this helicopter. Very well packed with all fasteners, and hard parts in a single box. Canopy looked very nice wrapped in plastic. CONS- Let’s move on to the instructions, very lacking in detail, not for a beginner enthusiast. (Not a beginner here). Do not buy a mini servo for the throttle. There are some adapters that does not come with the kit, and they don’t tell you either. Got them from HeliDirect. Ordering the adapters delayed assembly a week. Assembly hops around from head, tail, to side frames, where you have to guess at the bags of screws that are needed for the step. At least bearings are greased……Bags aren’t numbered like an SAB kit. Next con is the wiring. FBL tray is in the rear just in front of the boom. Throttle, and tail servo leads had to be lengthened, cyclic servo leads shortened. RPM back plate sensor wiring is just long enough. Then had to run a lead from NEO AUX1 to power the XGLOW. Very hard to route the wiring next to the elevator servo arm. Use a lot of wire ties. PROS-Lo and behold a very precision helicopter shows up out of the blue. The helicopter is very strong machine. Flies above the rest, yea guys, it’s that good despite the length of time it took to build. All said, the OS .55 has tons of power for this light/agile machine. Very easy to see, YOU WONT BE SORRY!!
