I have owned my DG-303 for 10 years. I think it is the absolute best design for the newer transition pilot coming out of club ships in a safety sense.. It does everything very well except winning racing competitions. The spar issue has been a non-issue after lots and lots of extensive study and research. Most of the ships they cut open did not have the problem and no one has ever had a problem with spar failure because of the construction flaw on the few ships that might have it. DG did a load test on a defective spar wing and it broke at over 9G's of load. The thought of the damage of cutting and repairing 4 holes in my wings to increase the safety margin from 1.4 to 1.5 just does not make sense to me especially when most likely most ships probably does not have the problem to begin with, especially my new one.. Come to Utah for a sit and see!!!
