Subject: Re: What is missing? - CG placement
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.
