Description

Dynam Sonic 85 3S Micro Parkfly Radio-Controlled Glider Trainer 850mm Wingspan - PNP/BNF/SRTF - DY8983 (Compact, Durable Parkfly Performance)

Theย Dynam Sonic 85ย 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 areasโ€”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 capabilityโ€”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 assembledโ€”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 smootherโ€”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 โ€“ 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.

X-Large is about a size 12-13 shoe size foot USA.
Material Type: Black - 3 Pairs, Size: X-Large
I love them they work fantastic. I am a big guy with swollen feet. Wear size 12 to 13 USA Shoes. They fit me just fine not tight. My feet felt good after wearing them for two days. Some dry skin pulled off with them and it says to wash by hand. I dont know about the durability but I am hoping to get about 5 uses per pair. Before they become unusable.

Comfortable
Material Type: Black - 2 Pairs, Size: X-Large, Material Type: Black - 2 Pairs, Size: X-Large
I have very sensitive skin, so I usually need to wear socks at all times. These are especially comfortable because they donโ€™t cover the toes, which helps with temperature control. The material is well-balancedโ€”not too thick or too thinโ€”and has just the right amount of stretch. I also appreciate the large traction area, which adds stability. Another plus is that they are completely fragrance-free.

Great Heel Socks
Material Type: Black - 3 Pairs, Size: Large
I don't know how they work but it's wonderful. I've had rough heel problems for a long time. I wear these everyday and my heels are not rough. They're not baby bottom smooth, but they are not ever going to be. These heel socks also oncce they are properly positioned snap onto the heel. Properly positioning them is easy when you put them on your foot with the heel cup in the correct orientation.

Too small
Material Type: Gray - 3 Pairs, Size: X-Large
Too tight! Even size large used for a man with smaller feet is too tight. Also, no instructions for use or care.

Good fit
Material Type: Black - 3 Pairs, Size: X-Large
My husband just started using these and they feel comfortable. Hasn't used them long enough to see if his heels are better. He has a high arch so I bought him the XL and they fit perfectly.
