Default Weighing airplanes

Probably a silly question but so often people speak of the weight of there planes.Have never seen any info on how they get this figure.Stand on bathroom scale,Hang from a fish scale,Never seen an airplane scale for sale?Someone must have a system for this,would think the bathroom scale wouldn't be accurate enough.Maybe one of those scales they used to sell to weigh your fish just hang the plane on it?Like to hear how they do it.Thanks!

A lot of people use digital fish scales, what you do to weigh it is assemble the plane, put the spinner on the scale and just hold the plane from falling over. that gives you the most accurate weight. Understand? put the nose cone of the plane on the scale, should be the only part touching and just lightly hold the tail so it wont fall over, that allows for a very accurate reading

Cheap... get the $5 dial indicating fishing scale. Hang the plane from a string. Fairly accurate from 2 lb to 45 lb. (range of scale is 0 to 50 lb. Has a decent handle and is easy to read.

The Zebco "Deliar" spring and pointer scales are only accurate in the range of 5 to 18 lb.

Both of these come with a built in tape measure... appx 3 ft.

Default Cheapest of all

I take mine to the local grocery store and weigh them on the produce scale, accurate and cheap.

Default Weighing Airplanes

I also use a digital fish scale, and weigh the plane by hanging
it from any surface that's strong enough for the weight.

But prior to buying the fish scale, I used this method.

Stand on bathroom scale (Digital if possible)
Note your weight (A)
Hold plane in hands
Stand on bathroom scale again
Note the weight (B)

Subtract A from B

People at grocery stores will normally be very happy to help, as it is a novelty to them. besides those are very accurate scales

Default Produce scales

They don't mind you putting a 1/3 scale cap on the scales? How do you balance it on that small pan??

Default Harness

Before I took my plane to the local grocery, I rigged a harness from which the plane could be hung. At the grocery, I removed the pan and noted the negative reading on the scale. I connected the harness to the hook, noted the reading on the scale and added the initial negative reading. The process was simple, quick and accurate.

I use a ballance beam that has a 4:1 ratio. I use pennies as the counter weights (long side of beam) One penny = .44 ounces.

I have wrapped pennies to make counting easy.

I have repeated weighing the models to test for consistancy within a penny every time.

To hang on the beam I use a small eye hook at the CG of the plane and smack dab in the center. As an added bonus you can easily ballance the plane ( for/aft & left/right) while you weigh it
