Goblin 420 Competition - ARF FACTORY BUILD
This model was built exclusively at the SAB factory in Italy. Naturally, all assemblies are checked and secured during factory assembly. The helicopter is therefore ready for installation of your drive and electronic components.
The brand new Raw 420 Competition is the latest evolution of the 420 size model from SAB, instead of being direct drive like its predecessor, it features a single stage gearing system. This allows you to optimize power, efficiency and flight time based on your specific needs by choosing your own motor size and KV.
The Raw 420 Competition can run on any motor size ranging from 2820 to 3220 and KVs ranging from 800 to 1000. With a variety of motor pulleys you now have the freedom to fine tune your head speed based on your motor of choice.
This little machine is lighter than its direct drive counterpart. It also features a new canopy design resembling the all popular Raw 500.
This helicopter is a breeze to build, it has a very low parts count and has many other cool features like a new and improved tail push rod that is very easy to put together, an integrated flybarless system antenna mount and much more.
This helicopter is designed to run on a 6s pack ranging from 2200 to 2700 mAh and comes with blades. You simply need to get a motor, servos (micro cyclic & mini tail), an ESC and a flight controller! We recommend either the HobbyWing 60 or 80 amp controllers or the Scorpion 06_80. All of these are excellent choices, if you are planing on doing mild 3D or sport flying, the HobbyWing 60 is the best choice, for harder 3D, then the 80 amp ESCs are preferred.
The kit ships with one battery tray, make sure to get more if you plan on having more than one battery ready to go.
