With Greystorks permission I am now updating this mod.

This parts pack contains engines, tanks, and other part categories in three sizes that do not exist in stock KSP, namely 5m, 7.5m, and 10m. Parts are color-coded according to the universal electronic color code, simply because the author is an old RDAF radar technician. Hence, size4 (5m) is yellow, size5 (7.5m) is green, and size6 (10m) is blue.

Engines are kept at reasonable thrust figures and are thus not overpowered compared to the thrust/size curve of stock parts. The same goes for reaction wheels. Big spaceships are going to be sluggish, as one would expect.

This parts pack contains config snippets from the Community Tech Tree by Chris Adderley.

NOTE: As of version v1.3.5, BAE no longer includes the Firespitter plugin, but supports both it and Interstellar Fuel Switch. Either must be installed to enable multi-fuel tanks. In addition, Cross Feed Enabler is required to enable cross feed to radially attached 'Predator' tanks.

ALSO NOTE: I have braught the mod version inline with the KSP version.

Recommended mods:

Interstellar Fuel Switch or Firespitter - enables multi-fuel tanks.
Cross Feed Enabler - enables cross feed to radially attached 'Predator' tanks
Community Tech Tree - extends the stock technology tree with lots of new nodes for your favorite parts packs to fill.
Kerbal Joint Reinforcement - ensures that your big spaceships suffer less from unplanned rapid disassembly.
KSP-AVC - ensures that your installed mods are up to date.

Enjoy!
