Complaint about the MAN!
Rein has it correct in that a really bad product won't make it to the review page at all. This was the policy at MAN during the peak RC helicopter years, presume it still is.
Eagle Flyer has a great point too as I have seen the very magazine at several friends homes. However a subscription only magazine in the RC world will never be a reality (it has been tried). Reasons are (1) the circulation base is too small to be cost effective and (2) Most RC'ers wont spend $10.00-$20.00 per issue to make it cost effective.
Again, I personally like all the magazines available and do appreciate the reviews. However it is still my responsibility to research a product before plunking down my money. And yes, I too have bought a few clunkers.
