Its not just GP, World has similar quality variations. VMAR is almost always truly bad. Kyosho probably has the most consistant quality. Oh well, what do you expect, for a bowl of rice a day anybody would be as disinterested in quality. Too bad the manufacturers still charge a lot compared to the pennies it costs them to have these manufactured in Nam or China. Some say that ARFs are a great bargain! Looking at the price escalation over the last 2 years alone, I see a 20-30 percent jump, now that is a little more than the typical inflation rate.
