Dossier 09 / Circuit

Training hop

A first-person circuit over a wartime-style strip. Angle mode by default. This is a school machine - honest physics, not a compiled Betaflight loop. For that, see the simulator dossier.

Briefing

W/S throttle - A/D yaw - arrows pitch and roll. Space arms. R resets. M changes mode. X cuts motors. A USB radio in joystick mode will take the sticks. On a phone, use the thumbs - left is yaw and throttle (throttle stays), right is roll and pitch.

Need the full Betaflight-in-the-browser project? That is WebFPVSimulator, GPLv3, hosted on its own origin.

Standing orders

How to use the simulator

Click the picture first so the keys stay here and do not scroll the page. Then arm, add a little throttle, and fly the six gates. Angle mode will level the craft when you center the sticks. That is the school setting. Switch to acro only when a hover feels boring.

Start

Arm, then climb

Arm & start or Space puts the motors live. The HUD must read ARMED. W adds throttle. S reduces it. A hover lives around mid-stick. If you crash, R or Reset puts you back on the strip.

Keyboard

Mode 2, same as a radio

W / S – throttle. A / D – yaw (nose left and right). Arrow keys – pitch and roll. Space arms or disarms. M swaps Angle and Acro. X cuts motors without a full reset. R is the full reset.

Radio or phone

Sticks you already own

A USB radio in joystick / USB gamepad mode takes the sticks automatically. On a phone the left pad is yaw and throttle (throttle stays where you leave it). The right pad is roll and pitch. The same Mode 2 a Radiomaster uses.

What the HUD is telling you

SAFE means the motors will not spin. ARMED means they will. CRASH means you hit the ground hard enough that the hop is over – reset and go again. ALT is height, SPD is speed, THR is throttle, and the voltage is a costume pack that sags as you fly. GATE counts how many of the six rings you have crossed.

Angle holds a bank only while you hold the stick. Center, and the craft levels. Acro holds the last attitude. Center in acro and you keep whatever roll you had. That is why new pilots stay in Angle until the circuit is easy.

This trainer is honest physics, not a compiled Betaflight loop. Use it to learn the picture and the four sticks. Then sit in a desktop sim or a real pack outdoors.

Key list

W / S – throttle up and down
A / D – yaw
Arrows – pitch and roll
Space – arm or disarm
M – Angle or Acro
X – cut motors
R – reset the hop
