How to Balance an RC Glider Properly (Step-by-Step)

Balancing an RC glider correctly is one of the easiest ways to improve flight performance and reduce crashes—especially for beginners.

This step-by-step guide shows you exactly how to set the CG properly, even if you’ve never done it before.

Step 1: Find the Recommended CG

Check:

Manual
Manufacturer website
Inside wing markings

If unavailable:

Start at 30% of wing chord from the leading edge

Mark the CG on both wings with a pencil or tape.

Step 2: Install Everything First

Before balancing:

Battery installed
Receiver installed
Canopy on
Motor and prop attached (if electric)

CG must be checked in flight-ready configuration.

Step 3: Balance the Glider

Finger Method (Most Common)

Place two fingers under the CG marks
Lift gently
Observe tilt

Balance Stand (Optional)

More precise
Useful for larger gliders

Step 4: Adjust the CG

If Nose-Heavy:

Move battery slightly rearward
Avoid removing nose weight at first

If Tail-Heavy:

Move battery forward
Add small nose weight if necessary

Use small changes — 5–10 mm at a time.

Step 5: Recheck and Secure

Once balanced:

Secure battery firmly
Ensure nothing can shift in flight
Recheck CG one final time

Test Flight Verification

On first flight:

Launch gently
Observe glide
Trim minimally

A correctly balanced glider:

Glides smoothly
Doesn’t balloon or dive
Requires minimal trim

Common Beginner Balancing Mistakes

Flying without rechecking CG
Adding too much weight at once
Ignoring battery movement
Trimming instead of fixing CG

Quick Beginner Rule

Fix CG before touching trims or throws.
