I've been using one of these for the past 25 years. Great for small pieces back when digital scales weren't affordable. But now I use my electronic scale most of the time.

There's an old story from N.E.S.T (New England Stunt Team) about one of the fella's finding some old U.S. Army surplus life rafts for sale at a Grossman's bargain outlet store. These rafts used balsa-wood for floatation and he got very excited. He told another flying buddy.. and the two of them went back to the store with a bathroom scale.. I can believe it.

EDIT.. Those rafts must have been like this Navy one from 1942

Congrats! What model was the 21" combat job in the vid link?

Roddie it is a scratch built job from years ago, when yo ask I had to go to the garage and get it off the wall.I think I will clean it up and recover it.

Old Guy

another thing to consider ( and I am by no means a expert) many sections of a good aircraft require differing densities and grains of Balsa or spruce or bass wood

Using ALL contest graded sub 5lb balsa is a mistake except for maybe ultra light indoor free flight

There are needs for spars of a specific strength, LE and TE also usually have a designed weight and density

The various parts that need to be molded..(bent into shape) must be a certain grain and weight

This is a complex subject

I tried hard to amass a selection that allowed me to replace typical kit "crap" balsa with what should be right and I failed

Some where ....maybe this thread... I suggested going to swap meets and buying old big RC kits for a low price

I GOT a LOT of good various grade woods in a real large Douglas DC-3 82 inch wing span Top Flite kit for not many dollars

I tend to think that the major KIT makers of the larger RC craft had to provide very good wood

I also got a Lanier's RC 17.5% Giles 202 ....48" wing span, 34" fuselage that had superb wood in it of under $20 at a swap meet

Yes a lot of the die or laser cut pieces are wasted...BUT in each case I think the stick and sheet wood in the kits would be $100s more than I paid
