I vote to split the categories BUT I'd like to see them listed as there own primary category instead of a SUB-category under one listing (Aerobatics say) This was what happened with the engines category and because of this the "Forum Jump" feature found on the bottom and/or top of a thread cannot be used as effeciently as you cannot jump right into the "giant engines" but rather have to click again once the screen loads with the sub-categories (engine disc, giant eng, twin and mutli cyl, rc fuels, tach readings, manufact. support).

Just my .02.............Mark
