❓ Frequently Asked Questions
The battery provides approximately 21 minutes of continuous flight time under ideal conditions. With two batteries included in the package, you get up to 42 minutes of total flight time.
Factors that affect battery life:
- Wind conditions (strong wind reduces flight time)
- Flying altitude and distance
- Temperature (cold weather reduces efficiency)
- Battery age and maintenance
Each battery takes approximately 60-90 minutes to fully charge using the included charging hub.
Absolutely! This is designed specifically for beginners. Here's why:
- One-hand control: Simple, intuitive joystick operation
- Automated flight modes: Automatic takeoff & landing
- GPS stabilization: Locked position keeps it steady
- Obstacle avoidance: Won't crash into objects
- Quick start guide: Get flying in just 5 minutes
We also include free video tutorials and access to our expert support team. Most beginners are comfortable flying within their first session.
💬 Pro Tip:
Start in "Beginner Mode" for your first 5-10 flights. This limits speed and adds extra stabilization while you learn.
Yes, indoor flight is possible! The compact size and lightweight design make it ideal for small indoor spaces such as:
- Large rooms (living rooms, basements)
- Gyms or warehouses
- Indoor sports facilities
- Conference halls
Important notes:
- The GPS might not lock indoors (that's normal)
- Flying indoors requires a large open space (minimum 30ft x 30ft)
- You'll want to disable object avoidance for better maneuverability
- Always ensure the area is clear of people and obstacles
Since it folds down so small, it's incredibly portable for taking anywhere!
Maximum transmission range: 10 kilometers (6.2 miles)
This is the theoretical maximum distance. In real-world conditions, you'll typically get:
- Open areas (no obstacles): 8-10 km
- Urban environments: 4-8 km
- With interference: 2-5 km
Important legal note: In most countries, you must keep the drone within visual line of sight (typically 500m). The extended range is available, but local regulations may restrict how far you can legally fly.
The connection is managed by our advanced 5GHz transmission system with automatic failsafe – if signal is lost, it automatically returns home.
Yes, but with some important conditions:
- Carry-on: The drone and controller can go in your carry-on bag
- Batteries: Must be in carry-on (NOT checked baggage) per TSA rules
- Lithium restrictions: Airlines have limits on battery capacity
- International travel: Rules vary by country – check before you go
Pro travel tips:
- Declare it during check-in (most airlines require this)
- Keep batteries disconnected during flight
- The compact carrying case fits perfectly in overhead bins
- Check your specific airline's drone policy in advance
That's why this is such a popular travel choice – it's the most portable option that still flies great!
