How to Find Center of Gravity on Rc Plane?

If you are flying a radio controlled (RC) plane, it is important to know where the center of gravity (CG) is located. The CG is the point at which the airplane’s weight is balanced. It is usually marked on the fuselage near the wing root.

To find the CG, simply place your finger on the mark and slide it until the airplane balances evenly on your finger. The CG is one of the most important factors in flight performance. It affects things like lift, stability, and control.

If the CG is too far forward, the airplane will be unstable and difficult to control. If it is too far back, the airplane will be very stable but may not have enough lift to take off or stay in the air.

  • Find the wing’s leading edge and trailing edge
  • The center of gravity is located at the quarter-chord point, which is midway between the leading and trailing edges
  • Measure the chord length (c), which is the distance between the leading and trailing edges
  • Divide the chord length by four to find the quarter-chord point (c/4)
  • This is where you’ll find the center of gravity on an RC plane
  • To double-check your work, measure from the nose of the plane to c/4 and compare it to measuring from c/4 to the tail of the plane
  • These two measurements should be equal if you’ve found the RC plane’s center of gravity correctly!

How Do I Find the Center of Gravity on My Rc Plane

The center of gravity (CG) on your RC plane is the point where the airplane’s weight is evenly distributed. This is the point where the airplane will balance if you were to suspended it from that point. The CG is usually located near the middle of the fuselage, but it can be moved forward or backward depending on the design of the aircraft and how it is loaded.

To find the CG, start by weighing your plane on a scale. Then, measure the distance from the leading edge of the wing to the CG point. This is calledthe moment arm.

To calculatethe CG, dividethe total weightof your airplaneby thenumber of inches in themoment arm.For example,if yourplane weighs 3 poundsandthe moment armis 6 inches,thenyour CG would be at 1/2 inch behindthe leading edgeof the wing.(3 lbs./6 in.= 1/2 in.) You can also use a ruler or tape measure to physically locatethe CGpoint on yourplane’s fuselageafteryou haveweighediton a scaleto determine its approximate location.Once you know wheretheCGis located,you can make adjustmentsas neededto ensurethatyourplanewill fly safelyand efficiently.

5 Ways to Find CG (CENTER OF GRAVITY) of RC Plane

Homemade Rc Plane Cg Balancer

You can make a CG balancer for your RC plane at home with just a few simple materials. This is a great way to ensure that your plane is balanced correctly, and it can also save you money on buying a commercial balancer. To make your own CG balancer, you will need:

-A block of wood (about 6″x6″x1″) -A dowel or rod (about 12″ long) -Two small weights (each about 1/2 ounce)

-Super glue or other strong adhesive First, use the block of wood to create a base for your balancer. Cut two notches into the top of the block, each big enough to hold one end of the dowel.

The notches should be opposite each other, so that the dowel forms a cross when placed in them. Next, take one of the weights and glue it to the center of the dowel. Then, place the Dowel in the notches on the block of wood, making sure that the weighted side is down.

Finally, add the second weight to the opposite end of the Dowel until your homemade CGbalancer is complete!

Aircraft Center of Gravity Calculator

As an aircraft flies, its weight is constantly shifting and changing. The center of gravity (CG) is the point where all of the aircraft’s weight is balanced. It’s important for pilots to know where the CG is at all times, because it affects how the aircraft will fly and how it will respond to control inputs.

There are a few different ways to calculate the CG of an aircraft. One method is to use a balance scale. This involves suspending the aircraft from two points and measuring how much weight is on each side of the scale.

The CG can then be calculated by finding the midpoint between these two weights. Another method is to use a moment arm calculator. This involves measuring the distance from various parts of the aircraft (such as the wingtips, tail, and engine) to a reference point (usually the datum line).

These measurements are then used in a mathematical formula to calculate the CG. The most accurate way to calculate the CG of an aircraft is by using flight test data. This data is collected during actual flights and provides detailed information about how much weight is being carried by each part of the aircraft.

Flight test data can be used to create a three-dimensional model of an aircraft’s weight distribution, which can then be used to determine its CG location. Knowing where your airplane’s CG is located at all times is crucial for safe flying. There are many online resources that can help you calculate your airplane’s CG, so be sure to do some research before your next flight!

Biplane Cg Calculator

The CG of a biplane is the point at which the airplane’s weight is evenly balanced. It is usually located near the center of the fuselage, between the wings. The CG can be affected by many factors, such as the type and amount of fuel, passengers, and cargo.

To calculate the CG of a biplane, you will need to know the following: – The empty weight of the airplane – The location of the datum (the reference point from which all measurements are taken)

– The arm (the distance from the datum to each item on board)

Where Should the Center of Gravity Be on a Glider

There are a few different schools of thought when it comes to where the center of gravity (CG) should be on a glider. Some say that it should be as far back as possible, while others say that it should be closer to the leading edge. Ultimately, it depends on what you want your glider to do.

If you want your glider to fly fast and have good maneuverability, then you’ll want to keep the CG closer to the back. This will make the glider more unstable, but also more responsive to inputs. If you’re just trying to cruise around and don’t need speed or agility, then moving the CG forward will give you a more stable flight.

Experiment and see what works best for you. There’s no one answer that fits everyone perfectly. Just remember that changing the CG can have a big impact on how your glider flies, so make sure you test it out before taking it out into heavier winds!


To find the center of gravity (CG) on a remote-controlled (RC) plane, start by measuring the distance from the leading edge of the wing to the fuselage. Then, measure the distance from the trailing edge of the wing to the fuselage. Next, add these two measurements together and divide by 2 to get the CG.

For example, if your RC plane has a wingspan of 10 inches and you measure 5 inches from both the leading and trailing edges of the wing to the fuselage, then your CG would be at 7.5 inches.

Hi, this is your friend Michael Sayers. I’m an automobile engineer, but I have become an expert on RC cars. Seems funny to you! After graduating in automobile engineering, I worked for a renowned car manufacturing company for six months only. A few months later, I joined a popular RC vehicle manufacturing company as a quality in charge. However, I’ve created this site Altimarc, to share my decade of experience with people looking for an RC vehicle who don’t have adequate knowledge about that.
