# Questions people ask

> The short answers. If yours is missing, the game's settings usually have it.

### Is Ledroon free?

Yes. During the beta everything is free, and beta players get a thank-you when version 1.0 comes out. After that, flying stays free: the physics, the OSD, the forest and FPV World, three drones, the beginner lessons, joining friends. A one-time "Pilot" unlock will add the other drones, Prague and the real world anywhere. No ads and no subscription, ever.

### Do I have to install anything?

No. Open the page and fly. The game downloads itself into the browser the first time, so the next start is quick and it works without internet. You can also install it as an app from the browser menu.

### Will it run on my computer?

Probably. It measures your GPU at the start, picks the graphics level, and lowers it during a flight if the frame rate drops. Chromebooks, laptops, Macs and gaming PCs all work. On a fast PC you can turn on Ultra and Cinematic.

### Does it work on a phone or tablet?

Yes, with on-screen sticks. And if you have a PC without a controller, your phone can be the controller: open the link the game shows on your phone and fly the PC with your thumbs.

### Which controllers work?

- An FPV radio over USB (RadioMaster, Jumper, TBS, any EdgeTX or OpenTX radio in joystick mode)
- An Xbox or PlayStation gamepad
- Your phone, as a controller for the PC
- Keyboard
- Touch on phones and tablets

Arm, turtle mode and reset can be put on any switch or button.

### Do I need an account?

No. Press "Play anonymously" and nothing leaves your device. Sign in only if you want your times on the leaderboards, your settings on every device, or to fly with friends.

### Can I fly with friends?

Yes. One player opens a party and gets a code, the others type it in. No server list, no lobby browser.

### Is the physics realistic?

Each drone uses its real weight, motors, props and battery, and a Betaflight-style flight controller with rates, PID, filters and airmode. Prop wash, battery sag and motor saturation are modelled. Acro, angle and horizon modes are there. We tune it against real flights and real pilots, and we want to hear it when something feels off.

### Is it good for learning FPV before buying a drone?

That is what it was made for. Start with the lessons, which go from the first take-off to power loops, then fly the drone you are thinking of buying. See [Learn FPV](https://ledroon.com/learn-fpv/).

### Who makes it?

A small team from Czechia. The sim started in a school drone club. [More about Ledroon](https://ledroon.com/about/).
