How about more informative flight tests, that give you an idea what the aeroplane might actually be like to own? Are there any significant ADs on it, are spare parts readily available, can it be certified in the UK (lots of "tests" of Eastern European microlights say that they can be flown at heavier weights in the "experimental" category. Not in the UK they can't...), and so on.
Any article submitted as a "flight test" where the author has flown for less than an hour with either a company demonstration pilot or the owner who's trying to flog his aeroplane should be binned by the editor!!
