Dimensioned aircraft models. Handling coefficients remain estimates.
CAP 232 · 1.475 m span · 2.30 kg. Start on low rates and carry speed through turns. Abrupt elevator at high angle of attack can deepen a stall or snap.
Starting at your estimated 2.70 kg with fuel. Enter a measured ready-to-fly weight when available. Changes restart on the runway.
Inspection pauses flight. Drag to orbit; scroll to zoom. Move your USB sticks or use the arrow keys and A/D to check the control surfaces.
Grass resistance acts at the wheels only. Presets are estimates for the Calmato’s small wheels. Changing surface resets the aircraft.
Gust fronts build and decay over 8 seconds. Shear changes crosswind smoothly around 20 m above the ground. Turbulence is the average component RMS, not a peak gust.
0° headwind · 90° crosswind. The compass points toward the wind source: the green tip shows where wind comes from relative to your view, not geographic north. A breeze and gusts are always present. Wind varies across the field, with height and over time.
Mode changes the touch layout. USB channels keep their calibrated mapping. Changing mode resets throttle.
EasyStar II: standard three-channel setup. The roll stick also operates rudder; optional ailerons are not fitted. Set throttle while held, then select Hand launch. Close throttle for a folding-prop glide and land on the belly. After landing, pick up the aircraft for another hand launch.
Skyward: ailerons 15/8 mm up/down, elevator 8/5 mm, rudder ±15 mm. Flaps remain retracted in this first version.
Trims offset the servo neutral within the mechanical limits. Positive elevator raises the nose; positive rudder steers right.
Rates limit control travel. Expo softens the centre. No automatic levelling. Set expo to 0% if already applied in your transmitter.
CAP 232 · .40–.46 glow engine and 11×6 propeller (estimated baseline).
Calmato · O.S. MAX-46SF · 7.45 cc two-stroke
Rated 1.43 PS at 16,000 RPM. Propeller: 11×6 (your setup; APC data). Calibrated to your approximate 12,000 RPM at full throttle on the ground. RPM can rise as the propeller unloads in flight. Power is provisionally calibrated for finite vertical climbing, with grass resistance separately tuned toward your roughly 50 m takeoff run. Actual thrust remains unmeasured. Partial-throttle response remains estimated.
Uncheck to restart while fuel remains. Reset refills the tank. Estimated endurance is 12 minutes at mixed throttle. The propeller can windmill with the engine cut.
EasyStar II: 1.366 m span, 700 g baseline, PERMAX 1100 KV, 3S 2000 mAh and 7×6 folding pusher. Wing/tail geometry and aerodynamic coefficients are estimates; no measured flight polar is available.
Eclipson Skyward: provisional 900 KV motor, 3S 2200 mAh battery and 11×6 propeller. Electric motor and propeller sound; no combustion or smoke. Actual installed equipment remains to be confirmed.
Synthesized glow engine with RPM, propeller tone and softened exhaust rasp. Calmato sound reference.

Calmato: 6-DOF rigid body, 24 wing strips, independent tails, fuselage forces, prop wash and spring landing gear. Aerodynamic coefficients and engine setup remain estimates pending flight measurements.
Cyan: aerodynamic panels. Amber: wing forces. Green: tails. Magenta: fuselage. White: thrust. Arrows use 0.12 m per newton. Inspect the aircraft for a close view. Arrows show the last physics step; surface demonstration does not recalculate airflow.
Retains the last 60 seconds at 10 samples per second. Reset clears the recording. Export includes CG, inertia, wind, RPM, controls, every aerodynamic component and wheel forces.
Usage and flight summaries are shared by default: gate openings, tutorial progress, takeoffs, crashes, flying time, distance and control type. No names, exact controller IDs or flight paths. The dashboard shows 30 days; older records are cleaned up as the service is used. You can switch this off at any time.
FrSky Taranis X7 / X7S and other USB joysticks. Attached controllers are selected automatically. Default order: AETR, throttle reversed. Calibrate if the controls do not match.
Checking for controllers…
Keep this page focused and move a stick or toggle a switch to let the browser discover the radio.
Already using the Gamepad API. Test Safari’s raw controller detection without the simulator.
The browser cannot list USB devices it has not exposed as game controllers. No driver or firmware change is made by this setup.
Calibration learns channel order, direction, centres and travel. It works with either throttle-stick position.
Right roll, nose-up pitch and right rudder should read +1 at full stick. Throttle should read 0% at low and 100% at high. Default channel order is AETR: aileron, elevator, throttle, rudder. Saved calibrations are preserved.

Built-in panoramas are saved between visits. Demo field has photo-projected ground, a collidable tree line and safety nets. Other fields use generic ground.
Photo-matched ground and obstacle depth. Boundary traced from your aerial photo, scaled by the marked 160 m pilot-to-tree-line measurement. Other distances and map bearing are estimates. Adjust these using measurements from the club; changes reset the aircraft.
The gold grid shows ground scale; outlines mark trees and nearby nets. The photo is projected from the fixed pilot position. Tree heights follow the skyline; exact tree trunks, chairs and equipment are not modeled.
Use a complete 2:1 image, at least 1024 × 512 pixels and under 50 MB. This preview stays on your device and lasts until you reload.
You can send an ordinary photo set in this conversation for preparation; the simulator itself does not stitch photos.
A normal Camera Pano is a wide strip, not a complete 360° × 180° sphere. For direct upload, use a full spherical panorama exported as a 2:1 JPG. Otherwise take overlapping original photos as described below and send them for stitching. This uploader does not stitch individual photos or fill missing sky and ground.
One or two extra ground-level photos of the runway and a photo of a known-distance marker help with scale. Overlapping photos from one position can be stitched; photos taken from different locations may need a reshoot. A 360° camera export avoids most stitching problems.
We can then prepare the panorama and publish it as your default club field. New uploads need their own geometry calibration; the club model is only applied to Demo field.
