How can i weight my plane for cheap??

[rogerh12]

Howdy;

Anyone know how to weigh my kitfox 4 accurately, but on the cheap?
My airport can't even weigh a plane that is less than 1000lbs, and they charge a bundle

Special bathroom scales, known to work good?

any help is appreicated.

Contact you local EAA chapter. They often have access to someone (or they have themselves) aircraft scales.

Local chapters, even inactive ones, are a wealth of knowledge and resources.

Three $14 scales I calibrated myself with known weights. If you need help get only one person. It is a simple process but some people make it way to complicated and it seems no two agree on the process.

I agree with Tom. That is a very easy way to get good numbers.
Just remember to remove the weight of tailstands etc.

I did the same with a single scale and two "dummy" scales (blocks of wood of the same thickness as the scale).

If your bathroom type scale does not read high enough to weigh your aircraft, you can double the range with a plank and spacer. Place the scale under one end of the plank and a spacer the thickness of the scale under the other. Chock the aircraft wheel in the middle of the plank. Multiply the scale reading by two and subtract the weight of the plank. (The scale registers only half the weight of the plank, but you multiplied it by two.) The length of the plank doesn't matter, but a longer one, say about six feet, is more accurate.
