Robans new 470 size B AH-1W is now available.
Our new True Scale Design locates the cockpit exactly at the right spot, unlike most fuselages that are based on 3D mechanics. The compact mechanic is built into the engine compartment, just like on a real helicopter. Therefore it allows space for front to back scale cockpit seats. The position light system programmable with 9 different patterns is preinstalled.
The fuselage of the B AH-1W stands out through the detailed crafted surface details and the overall correctly scaled down shape. This unique scale look and details stun and make it hard to see the difference to a real helicopter.
The helicopter comes with a detailed instruction manual. The setup is simple and quick, the mechanics are completely preassembled. Only screw drivers and allen keys are required to make it airborne.
