The Dynam Sonic 85 is a micro-scale version of the Sonic 185, with wingspan reduced from 1850mm to 850mm for true small-field flying. Its compact design removes space limitations, making it ideal for parks, sports fields, and tight flying areas—while still delivering both gliding efficiency and high-speed performance.

Powered by a 3S 450mAh LiPo battery and equipped with the SR66A system, the Sonic 85 features Istone intelligent flight technology for effortless hand-launching, smooth control, and stable flight. It's beginner-friendly yet engaging enough for experienced pilots seeking relaxed flying.

A factory-installed brushless outrunner motor and folding propeller provide strong thrust and rapid climb performance. With a 3S setup, the aircraft delivers impressive speed and even vertical climb capability—no upgrades required.

Built with a durable, impact-resistant airframe, the Sonic 85 ensures reliable landings and long-lasting performance. The model comes almost fully assembled—just install the battery and you're ready to fly. Lightweight and portable, it's perfect for flying anytime, anywhere.

Features

Proven Design, Optimized for Park Flying
Derived from the Sonic 185, the Sonic 85 maintains excellent glide efficiency and predictable handling, now in a compact 850mm wingspan that's easy to transport and fly almost anywhere.
Stable Flight with iStone Gyro Assistance
Pre-installed SR66A iStone stabilization receiver enhances control and wind resistance, making takeoffs, cruising, and landings smoother—especially for newer pilots.
Wide Flight Envelope
From slow, controlled glides to faster powered flight, the Sonic 85 adapts easily to different flying styles. The ESC brake and folding propeller enable efficient soaring and clean glide performance.
Reinforced, Field-Ready Airframe
Carbon fiber reinforcements are embedded throughout:
- Wings: dual carbon spars
- Fuselage: four reinforcement rods
- Horizontal stabilizer: integrated carbon support
- This results in a rigid, durable structure that holds up well under frequent use.
Abrasion-Resistant Protection Design
Four integrated skid fins on the fuselage and wing roots help protect the airframe during rough landings and ground contact, making it suitable for grass, dirt, or uneven surfaces.
Enhanced Wing Structure & Control
- Dual ailerons for improved roll authority
- Additional vertical supports at the wing root for increased strength and stability
Clean and Practical Assembly
- Screw-fixed wing for secure installation
- Glue-fixed horizontal stabilizer for simplicity
- Magnetic canopy for quick battery access
- Ball-link control rods for precise, slop-free control

SRTF Option – Easy Hand Launch Capability
The SRTF (Super Ready-To-Fly) configuration supports hand-launch flight even without active control input, offering a stress-free entry point for beginners.
