Apex Aerotech 116" Laser – High-Performance 40% Aerobatic RC Aircraft

Raise your aerobatic performance to the next level with the Apex Aerotech 116" Laser, a championship-inspired giant-scale RC aircraft engineered to combine the commanding presence of a 40% airframe with the agility and responsiveness of a smaller aerobatic model.

Inspired by the legendary full-scale Laser aerobatic aircraft, famously flown by Leo Loudenslager, the 116" Laser brings together iconic styling, an expansive flight envelope and impressive precision. Designed for demanding aerobatic pilots, it delivers the versatility required for high-level IMAC competition, classic low-and-slow 3D manoeuvres and high-energy XA-style flying.

Engineered for 150–240cc petrol engines, the Laser accommodates both twin-cylinder and four-cylinder configurations without airframe modifications. Extensive design development and testing have focused on bridging the performance gap between 120cc models and traditional 40% aircraft, resulting in an impressive combination of agility, precision and large-scale presence.

Available in two distinctive liveries designed by Clint Sweet, the Laser offers a choice between the classic-inspired Retro colour scheme and the bold, modern Velocity finish.
