I've done a little better than 30mins, even at USIC. I agree with Larry. I rather make a prop 67mg then the motorstick so short and light. Looking at Kangs plan it looks like a lot of weight can be removed from the wing and prop and/or added to the motorstick. My 7" USIC winner was 320mg total, with the prop <70mg and the stick around 90mg (bare wood) that model did 31:26 unofficially at USIC and almost 34 at about 135ft at Lakehurst. I've had an 8" model in the making.. the 8" blank MS weighs around 100mg. I think Ray Harlan has taken my design and ran with it successfully at USIC the years I've been absent.
More props to Kang for coming out from California, and getting it done in the middle of the night at Lakehurst! Even if you made sturdier 400mg models with 8-8.5" motorsticks your models would still fly just as well in places like Tustin and Lakehurst as long as they're properly trimmed.
