Last year I launched a couple of rockets with 3/16" launch lugs on a 4' length 1/8" diameter launch rod and experienced no problem. Each rocket was equipped with two lugs, one astride the CG and the other very near the aft end of the tube. Now I'm building a slightly heavier and more powerful rocket that I propose to equip with 1/4" lugs and launch on a 3/16" rod. The new rocket weighs 9.5 ounces ready to launch, and uses a D12 or E14 motor. Other than a minor drag penalty, could there be any objections to this mismatch?
