Part Tweaks

A few modifications that I've found useful:

• Add bottom attachment node to the Toroidal Aerospike Rocket engine: navigate to GameData\Squad\Parts\Engine\toroidalAerospike, open part.cfg, and add the following under node definitions:

node_stack_bottom = 0.0, -0.8, 0.0, 0.0, -1.0, 0.0, 0

Note that when placed over a decoupler, the engine will not gain a fairing (probably because it doesn't exist in the original model). Also, though the connection through the bottom of the engine is actually quite strong (despite appearances), you may want to add struts to give it a little more realism.

• Make the Clamp-O-Tron Sr. Docking Port a root part: navigate to GameData\Squad\Parts\Utility\dockingPortLarge, open part.cfg, and change the attachRules = 1,0,1,0,0 line to attachRules = 1,0,1,1,0

• PartTweaks tweaks some of the stock parts to make them more realistic. More informations on it's forum thread.
