These stats were reverse engineered from the Heli Attack 2 swf file. Feel free to add some neat graphs and stuff on these statistics.

Heli Attack 2 Gun Statistics[]
| Weapon | Damage | Bullet Speed (Higher is Faster) | Reload Time (Every n Frames Per Second) |
|---|---|---|---|
| MachineGun | 10 | 8 | 5 |
| AkimboMac10's | 9 | 8 | 4 |
| Shotgun | 15 | 8 | 25 |
| ShotgunRockets | 40 | 7 | 40 |
| GrenadeLauncher | 75 | 15 | 30 |
| RPG | 75 | 4 | 40 |
| RocketLauncher | 100 | 7 | 50 |
| SeekerLauncher | 100 | 7 | 55 |
| FlameThrower | 2 | 8 | 1 |
| FireMines | 5 | 3 | 100 |
| A-BombLauncher | 300 | 3 | 150 |
| RailGun | 150 | 20 | 75 |
| GrappleCannon | 300 | 20 | 250 |
| ShoulderCannon | 300 | 20 | 100 |
Things to note:
Everything is pretty balanced
ShoulderCannon is obtainable by entering PredatorMode (powerup)
AkimboMac10's are actually more powerful than the FlameThrower
GrenadeLauncher and RPG make a good combination, as with RocketLauncher and SeekerLauncher
ShoulderCannon is the most powerful insta-kill weapon (For every 3 ShoulderCannon shots, only 2 A-BombLauncher shots have been fired).
RailGun and A-BombLauncher are equivalent in terms of rate of killing (every 2 RailGun shots, which brings down 1 heli, is equivalent to 1 A-BombLauncher shot).
Other things I discovered:
Health packs drop every n=n*2 helis, helis always have 300 health, normal gun does 10 damage (I could list off the others but there are too many for this tiny box), flamethrower has a reload time of 1 (normal gun, 5), reload time for A-Bomb Launcher is 150, and the longest reload time? Grappling gun with 250. Another neat fact is railgun and grappling gun move at the same speed : )
Powerups appear every 3rd heli destroyed
You only have 3% chance of getting a 'random weapon' powerup (the powerup that is visually cycling through all the power ups)
If you perform a killing blow on a heli during a superjump, you are guaranteed to get a random weapon (Which is awarded directly, not through a box)
Unsure:
As levels go up, the heli's accuracy increases, but nothing else.
