What is R/C Soaring?

More Than a Model Plane. A Flying Laboratory.

Ask a PASS member why they drive 45 minutes to a grass field on a Saturday morning and they'll struggle to explain it. Then a plane catches a thermal and climbs silently to 500 feet — and you understand immediately.

RC gliders fly without engines, riding the same atmospheric forces that carry hawks and eagles aloft. To fly well, you have to understand the sky — thermals, ridge lift, wind gradients. Many of our members went on to aeronautical engineering, commercial aviation, and aerospace careers. It starts here.

For Educators & Students

A Living STEM Curriculum

Every flight session is a hands-on lesson that sticks because it's real.

Aerodynamics

Lift, drag, and glide ratios become real when you're trimming a sailplane for a 10-minute flight on a single launch.

L = ½ρv²CLS
Lift Equation

Meteorology

Reading thermals and wind gradients isn't optional — it's how you stay up. Real atmospheric science, every session.

☀️ Surface Heat → Rising Air → Lift

Systems Engineering

Radio systems, servos, composite airframes, control surfaces — a sailplane is a miniature aerospace system.

WINGSPAN   : 2,400 mm
ASPECT RATIO: 24 : 1
ALL-UP WEIGHT: 310 g
MATERIAL   : Carbon / Kevlar

Math & Strategy

Flight window optimization, scoring, trajectory decisions — applied mathematics under real competitive pressure.
