RJX X-TRON 500 Electric Flybarless 3D Helicopter Kit

High Performance Flybarless Electric Helicopter


Kits are still in

This new kit from Hobby King has all the makings of a fun 3D Heli. It uses all high quality parts including a carbon fiber main frame, and aluminum parts where it counts like the bearing blocks, and head and tail assemblies. It has a CCPM servo setup for precise control and a belt driven tail. The ESC plate is up top and gets airflow from the main blades to keep it cool during hardcore flying abuse. With all the RTF helis out there, it's great to see a kit on the market. If you've never had the pleasure of building a heli from parts, we highly recommend you give it try. It's a great way to learn the mechanics, and will make repairs a lot easier. Check out the RJX X-TRON 500 3D heli at HobbyKing.
