RE: RC hobby Market SLUMP?
Did you try upgrading your ad for more visibility? Not trying to push you to spend money here but the volume of ads in the last 2 months has gone up significantly. This makes your ad one of a larger pool of ads. If you want your ad to be seen by more users a feature upgrade, forum feature upgrade, homepage upgrade, etc might help it move faster. Those who upgrade ads on RCU sell faster and for more money on average by a significant percentage according to our stats that we mine.
