Fighters -
a) nova v. Good ship, easier to get en mass then the solano, except more expensive (iirc). again, L version has all you need in a fighter. Slower and less maneuverable, but much bigger guns to make up for it. Better missile selection if you need those
b) falcon haulers make excellent cargo ships.. XL cargo and a good deal of it. Not sure why you would use them in combat over the falcon sentinel. Sentinel has 1x 200mj shield...
c) solanos are easy to buy and fit (the L version contains PRGs, otherwise hard to get off the market). They have m4 maneuverability and speed with m3 shields, rather survivable. Pain in the ass to upgrade rudder and engines.
novas and solanos are both good choices, with the main difference being prg vs hept, (although some prg fit novas anyway).. The rear turret makes a small difference if missiles are being thrown around, and of course the lack of proper eq-dock in legends home. This makes sense later when you 'get' to fit 30 solanos with engine/rudder.. one by one..
OOS: Combat takes into account guns and shields, and to a slightly different extent, turrets.. Solanos will do fine.
A codea carrier with a wing of a dozen or so solanos could probably easily take care of minor pirate problems in a single system. Of course, be sure they dont decide to suicide themselves into a galleon or something..
Kestrals are fine OOS (no collisions), and generally as long as they are set in the recon hangar they stay out of the way of things. Its nice to have the extended view range when you are trying to find stations in a system like er.. the teladi one that has 'vault' in it? egh cant remember
Crashing issues I cant particularly help with. All i can say is avoid the system - cloudbase southeast, while being a weapons hub... has no clouds.
Southwest, over by the paranids, i think has clouds.. no real point being in that system imo.
