One more question.
Is the CG correct according to the plans?  This glider, especially 
with the stock tail length and increased wingspan is very sensitive 
to CG placement.  If you haven't increased the tail length then the 
CG needs to be further forward to get the same stability as the stock 
winged Bug.
