You'll need to learn how to modify upk files with hex editing. This takes some time and practice to figure out if you haven't done it before. You should start here: http://wiki.tesnexus.com/index.php/Category:Tutorials_-_XCOM:EU_2012; there are several posts within this forum that may help.

 

UFO Hit Points are set in XComStrategyGame.upk >> Class XGItemTree >> Function UpdateShips ()

 

This is my modded line for the small scout: UpdateShip(4, 2500, 40, 750, 0, 7);

Small Scouts are Ship #4. Hit Points are the fourth parameter in the function (in this case, 750)

 

Weapon Accuracy is set in XComStrategyGame.upk >> Class XGItemTree >> Function BuildShipWeapons ()

This is modded line for UFO Plasma Cannon I, the single-shot alien plasma weapon

BuildShipWeapon(8, -1, 101, 1.250, 500, 0, 33);

 

Accuracy is the last parameter in the function, in this case 33, which is a percent chance to hit.
