REAL RC HELICOPTERS WERE IMPOSSIBLE TO FLY.
IT WAS BEFORE THE SENTINEL.
⭐️⭐️⭐️⭐️⭐️ (4.9/5 | Recommended by aeromodelling enthusiasts
Ready to leave toys behind for the thrill of real piloting?
Bi-rotor helicopters are stable, but they don’t fly like the real ones. The Sentinel is your entry ticket into the world of authentic aeromodelling. As a replica of the legendary Bell 206 Jet Ranger, it offers you the agility and look of a professional machine, with stabilization technology that gives you total confidence.
Stability at the pilot’s service.
Total control, flight with absolute serenity.
THE SECRET: THE INTUITIVE 6G MODE.
The Sentinel uses an ultra-efficient 6-axis gyroscope. In 6G mode, it automatically stabilizes on all axes. Combined with barometer-based altitude hold, it gives you the confidence to master every maneuver. Let go of the controls, it hovers in the air and waits for your commands.
THREE LIVERIES, THREE MISSIONS.
Fire Rescue Edition

MASTER REALISTIC FLIGHT.
The Sentinel is a 4-channel helicopter. You control all the essential movements of a real pilot: throttle (altitude), yaw (rotation), pitch (forward/backward), and roll (left/right). It's the best way to master the true basics of flying.
THEY WANTED TO TAKE IT TO THE NEXT LEVEL.
"The perfect transition!" ⭐️⭐️⭐️⭐️⭐️ "I had a small bi-rotor helicopter and I was bored. The Sentinel is exactly what I needed. It's much more responsive and fun, but the 6G mode really helped me avoid crashing at first. It's the best of both worlds." - Marc V., Verified Customer
"Incredible for the price" ⭐️⭐️⭐️⭐️⭐️ "I'm amazed by the quality for such an affordable model. The design is superb and the stability in beginner mode is really effective. Perfect for practicing single-rotor flying without breaking the bank." - Lucas T., Verified Customer
Our Expert's Rating
"The Sentinel is the missing link. It uses brushed motors, a smart choice for an ultra-light 95g model. This makes it very affordable, less intimidating, and perfect for getting started with single-rotor flying without investing in an expensive brushless model. It's the best simulator... in real life!" - Certified Test Pilot

PRE-FLIGHT CHECKLIST
🚁 What is the difference with a toy helicopter?
A toy often has two pairs of blades (bi-rotor) spinning in opposite directions, which makes it stable but very limited. The Sentinel is a flybarless single rotor, like a real helicopter. It is more agile and lets you master the true mechanics of flying.
⚖️ Is it fragile?
It is designed to be both lightweight (95g) and durable. Its lightness is an advantage: less mass means less energy to dissipate on impact. Additionally, it is equipped with electronic protections (stall, low voltage) and spare blades to keep you flying.
⚙️ What type of pilot is it for?
It is ideal for pilots seeking the authentic sensations of a single rotor, with reassuring stability. Experienced pilots will appreciate it for the realistic and relaxing "scale model" flying pleasure, perfect for having fun without the stress of competition machines.
