[NSRCA-discussion] Small Models ... good for the futureofthePattern Event?

[Fred Huber]

If the wings go on with a wing tube... you can ballast it with lead shot.  A 
couple of EPP plugs to keep the shot centered (epp will compress easy enough 
but  not tle the shot move in flight)

The wing tubes tend to be on CG... and this method is essentially what is 
used for varying the sailplane weight in one competition class (they don't 
use anything to keep the shot form moving in the tube... but accurate 
aerobatics are not required...  The shot tends to self level in level flight 
so it doesn't bother trim enough to matter)

You can also put a metal cigar tube in any plane on the CG.... Lead shot 
holder with a screw-on cap.
