Default Scale

I have often read posts about how much he/she planes weigh after completion and have oftem wondered what type of scale is being used. I have finished a plane recently and am wondering if it is to heavy to get off the ground. I would like to weigh it but am not sure where to find a scale and what would work for RC planes and best way of weighing it. Do I hang it from the fuse or do I set it down on a scale similar to ones used in the grocery store for fruit. do you need to get your scale calibrated, any suggestions? I have never seen a picture/video of anyone weighing their plane. I know it may seem like a common sense answer/question but anyhow there it is

Happy flying may your crashes be limited and if they are not limited let them be cool.

Depends on how big the plane is. I have a couple that I have weighed the parts then added it up. Another one I balanced it on the spinner till I got a good reading on the scale. Nice to have I have weighed my batterries motors and such to help me figure what my AUW while I am building a plane. After you get one you will wonder how you got by with out it. Nice to know what the plane wgt. is and if you built it and it is within what the manufacturer says it should be.

I bought mine on ebay from this place.

By the way I bought the 36 lb scale more than enough for my use.

Why not just stand on your bathroom scale while holding the plane
and then without holding it and subtract the two weights. That is pretty
close. If you know somebody with a baby scale, those work pretty good
too. Or a decent shipping scale would work, too.

Helicopters don't really fly.......
They're just so ugly, that the earth repels them.

Bonez-How heavy do you estimate the Hawk to be? I can't imagine it is any heavier than mine, since you made pretty much the same upgrades.

Toss that thing in the air and see what happens! (pluck the landing gear-it only makes it look goofy!)

Oh-tape the heck out of the nose, first!

All of my landings are three point landings if you count the spinner, too

Teach using the LAR Theory and using Heli Jim scale method it came to about 3lbs.
I have yet to give her a toss the snow has gotten pretty hard at the moment so we will wait.

However I was real curiouse about what other people use for their scales. I though about your everyday Kitchen scal but was unsure how accurate ones scale should be. I also assume the weight of a plane would also be a way to help one figure out what size motor and prop to use on a plane. May be standing in the weeds on this but thought I would just ask

Happy flying may your crashes be limited and if they are not limited let them be cool.

I use this one from WalMart. Around $5.00, I think.

I use a Blade digital scale, for which I paid about $9.


It is sometimes a PITA to get the plane balanced over the scale and then a bigger PITA to read the display which is now hidden under the plane, but it was cheap, reasonably accurate, and goes to 1KG in increments of 0.1g.

I often stack some sanding blocks, or childrens' blocks, or something on top of it to make a kind of pedestal for the plane to rest on. The scale zeros out this extra weight when I turn it on.

FWIW

I use the triple beam balances at school. Realize I am lucky to have those. Right now the snow is still coming down and we are without power. The leaves are still on the trees and that is wreaking havoc on the power grid. Starting to get chilli in our house!
