I have built three different Mongoose two-stagers, following the directions to the letter each time. The booster DOES NOT tumble and the front end has been crumpled on the first flight three consecutive flights. I have 3 Mongoose upper stages, wrote Estes, and am awaiting a new Mongoose gratis,which is greatly appreciated. Estes claims that they've had no other complaints about the booster problem; has anyone else experienced this; what's a good way to prevent it from happening again?
