RC aircrafts with retractable landing gear

 

— the ability to retract and extend the landing gear is similar to what happens in many real aircraft.

In addition to additional similarity with full-size technology, the ability to “tighten the legs” allows you to make the device more streamlined, improving its speed and aerodynamics. These advantages are especially noticeable on powerful acrobatic equipment (see "Aircraft Type"); but in more modest models, the purpose of this function is rather aesthetic.
