Modern transmitters allow you to adjust rates and exponential (expo), but many beginners don’t understand what these settings do — or why they matter.
Correct expo and rates make your RC glider easier to fly, smoother, and more forgiving.
What Are Control Rates?
Rates control how much the control surfaces move.
- High rates = aggressive response
- Low rates = smooth response
What Is Expo?
Expo softens control response around center stick while keeping full control at the ends.
👉 Expo = smoother flying without losing authority.
Recommended Beginner Settings
Elevator
- Rates: 60–70%
- Expo: 25–35%
This prevents over-pitching and stalls.
Ailerons
- Rates: 65–75%
- Expo: 20–30%
Helps avoid sudden banking or wing drops.
Rudder (If Equipped)
- Rates: 70–80%
- Expo: 15–25%
Useful for coordinated turns and thermal flying.
Dual Rates: Do You Need Them?
Yes — but keep it simple.
Suggested setup:
- Low Rate: Normal flying
- High Rate: Landing or recovery only
Avoid switching rates mid-turn.
Common Beginner Mistakes
❌ No expo at all
❌ Too much elevator travel
❌ Changing settings every flight
👉 Fly a full pack before adjusting.
Simple Test Flight Checklist
- Calm conditions
- Cruise mode
- Gentle stick inputs
- Adjust only one setting at a time
Final Thoughts
Expo and rates don’t make your glider harder to fly — they make it easier. A properly tuned glider feels smooth, predictable, and confidence-inspiring.
