This is another hobby shop sale find that I couldn’t resist.  I have always loved the glider style rockets. Sadly, from all the reviews I have read this model is one of the greatest mistakes that Estes has made. This model does not fly right and usually crashes quite hard most of the time. As such, I plan on building this strictly as a shelf model.
