BO-105 Orange and Blue 800 Size Scale Helicopter ARF (Almost Ready to Fly) from Roban - RCH-BO105RWB8

This is the Roban BO-105 Orange and Blue 800 size ARF, a premium scale kit that offers unparalleled detail. From tip-to-tail the BO-105 body kit displays an accuracy of detail to the real aircraft not normally seen in the RC helicopter hobby.

This kit comes with a fully illuminated scale detail cockpit with illuminated dashboard, joysticks, rudder pedals, aerials, windshield wipers and more. Full rear cabin interiors are included (not installed). Floor and ceiling details can be crafted so once the interiors are installed you have an impressively scaled cockpit/interior.

These scale kits house the cockpit in precisely the right location and the mechanics are built into the engine compartment just like in the full scale version. The BO-105 Red and Blue really impresses with the highly detailed and accurately scaled down profile.

Important Information - Please Read

Roban Scale Helicopters are intended for modelers who have advanced level building skills. Both ARF and KIT product formats require you to install your own electronics (ESC, servos, motor, etc). KIT product formats also require you to install your own helicopter mechanics. Because helicopter mechanics can vary greatly in size and shape, you may be required to modify the fuselage slightly (including cutting, drilling, etc.) to achieve a perfect fit. Roban fuselages are all handmade from fiberglass and therefore may have slight variation in tolerances between body panels, doors, or windows. These variations do not affect flight performance and can be easily adjusted by an experienced builder with proper tools. These precautions are intended for novice builders; an experienced modeler should have no issue achieving perfect results with these premiere scale helicopters kits.
