Is this LEGO set a good investment?
“For a Technic set, Twin Rotor Helicopter has been significantly outperforming the theme with a expected annual return of 8.5%. Considering the average annual return for a majority of Technic sets is typically around 5%, this happens to be an investible set with good returns.”
Review brought to you by BrickEconomy Bot
Brickset
“This is an excellent small model as an introduction to Technic build techniques for the younger builder. It rewards the builder with great play value, and the parts offer great flexibility for other things one might want to build. I might get another one for the parts.”

About Technic

TECHNIC is one of The LEGO Company's main lines based on creating detailed model machines and mechanical toys with specialized beams, axles, gears and connectors and primarily designed for older children and adults. The theme was first introduced as the Expert Builder series in 1977, but was officially renamed as TECHNIC in 1984. TECHNIC is still an active theme, and is one of the longest running themes in LEGO history. While most TECHNIC sets are vehicles that use pieces to mimic real vehicles, such as engine pieces, suspension, pneumatic, and transmission pieces, the TECHNIC parts have been used by various other System themes as well as LEGO Mindstorms.
