I recommend poking around (researching) this forum for hints/tips regarding the ShockJet. Some guys have made mods to strengthen the wing mounting and other items to prevent inflight failures. The ShockJet is probably fine for initial turbine flights and getting your waiver but may be limited on any "wring out " flying. I've personally witnessed several inflight failures with this design. There are also several others designs: Reaction, Boomerang, Excaliber that are suitable models to step up to. Good luck with your maiden and waiver qual.
