I have a gripe with some of the used prices on most of classified forums. Why does so many people have NIB engines or just ran one tank of fuel thur them. In the real world good used brings 50% of new price , but alot of RC's use this equipment hard for several years and then pedal it for the almost new price. Most buyers are newbies that haven't done their homework yet , so I feel they are cheated. For instance one guy advertized 4 standard servos used for 4 years and asked for $100.00 You can get those servos at any LHS for 12-15 apeice which is near $60 plus tax. See what I mean ,What a cheat, Just my .02 Sell used treat someone fair.
