Query: unbelievable reviews

I cannot believe that a supposedly knowledgeable reviewer could be so wrong. ie. all of the **** and ***** reviews. This Book has NOTHING in It of value. It is a TOTAL waste of time if You are remotely familiar with the construction of RC Aircraft. I'm not a Kid anymore (79 Yrs)and I'm so tired of BS that it makes Me want to throw Up !!! and by the way I have been a Full Size Aircraft Pilot practically all of My Life so forget Your little insinuation's about He doesn't know what He is talking about. Save Your Money !!!
