well, it is easier to share this instead of working on it with my limited inteligence and Knowledge, so here it is: my list.

1. damage and health.

the damage System is still not perfect, but we can fix this.
all we Need to do is to calculate the force needed to destroy a block with the health x (force in lbf/ft² or Newton/cm²) and also the damage of guns (again force in lbf/ft² or Newton/cm²).

that would help us to make better replicas for dogfights

2. Flak for AI

if you care, i have uploaded working flak a few minutes ago, you can get it here.
its working fairly good, but ai cant handle it. what we need is flak that ai can Control.

3. AI aiming

im talking about for example a Missile inside a box, and whn you fire it, the Missile will autoaim at the plane. i got a prototype here. sadly tho it wobbles too much.

so if you have time and Patience, feel free to fix it. i think some People would appreaciate it
