Overview

This guide explains how to use the Lake Sawyer Hawks CG Balancer with your airplane and the online calculator. It combines accurate scale readings and distance measurements to locate your model’s Center of Gravity and determine if it’s nose- or tail-heavy.

What You’ll Need

Two digital scales (e.g. AMIR 500g × 0.01g or 1000g × 0.1g)
A level tail support or block for the tail wheel or skid
A ruler or tape measure (in inches or millimeters)
A bubble or digital angle level
Your phone, tablet, or laptop with the Hawks CG Calculator open

Step 1: Prepare the Aircraft

Install the flight battery, canopy, and all flying components.
Ensure the airplane is flight-ready — same condition as when flown.
Verify the horizontal stabilizer is level using a small bubble or digital level.

Step 2: Set Up the Balancer

Place the two scales on a firm, level surface — spaced to match the main gear width.
Place each main wheel centered on a scale pad. Use small wooden pads if needed to protect the scale.
For taildraggers, support the tail wheel with a block or stand so the horizontal stabilizer is level to the ground.
For tricycle gear, level the airplane so the main gear and nose gear are all in contact with the scales at their normal ground attitude.

Step 3: Measure Distances

Using a ruler or tape, measure the following distances along the aircraft’s centerline from the spinner tip (or other fixed reference point):

AB = from nose tip to front (main) wheel center
AD = from nose tip to rear (main or tail) wheel center
AC = from nose tip to recommended CG location

Enter these values in the calculator exactly as measured. You can switch between inches and millimeters in the tool.

Step 4: Take Weight Readings

Zero both scales with the aircraft off.
Gently lower the plane onto the scales and tail support.
Read and record the left scale weight (WB) and right scale weight (WD). If your rig uses only one main wheel, record that single value.
Enter the two readings in the calculator.

Step 5: View the Result

The calculator instantly computes your actual CG position and compares it to your forward and aft limits. The aircraft graphic will show a highlighted CG marker:

Green glow: Balanced within range
Amber: Slightly nose- or tail-heavy
Red: Out of balance — adjust battery or ballast

Step 6: Re-Adjust & Re-Test

Move your battery or add ballast until the CG marker falls within the acceptable range. Small shifts forward or aft can dramatically change handling, so fine-tune carefully.

Final Check

Confirm the stabilizer is still level during measurement.
Repeat the reading twice for consistency.
Document your distances and scale readings for next time.
