I'm looking to clear a forested area to build a new base. Is there any good way of doing it other than getting an axe and going chop chop chopping?
In 1.4.7 I'd use Forestry logger with energy cell and chest/void pipe next to it. One logger is enough for 21x21 area, taking down trees that start on similar Y level as logger (it is about 6 blocks IIRC). It may not get all of the branches, specially with RP2 rubber trees, but it was a godsend for redwood/fir trees. In 1.5 you can use tier 2 lumberjack axe from TConstruct or DartCraft force axe with lumberjack upgrade.
