The intention of this post is to clarify the size and design of the balsa chuck glider that should be utilised in the “Balsa Model Flight Competition” at the AAL Federal Review

A few comments have been received that the use of the AAL Aircraft Modelling Class 4 Work Booklet could be problematic as there are several versions in circulation resulting in issues such as some workbooks having inconsistent plans, for one reason or another. A standard plan is attached to this document which may help those who have found the workbook plan inconsistent and feel they would be disadvantaged in some way.

Details can be found in Federal Air Activities Instruction 20 Addendum online here.
