Each Builder Hall raises the Copter's cap. The table shows the Builder Elixir and time to climb from one cap to the next, counted from level 15 (the 2,500,000 unlock is not included).
Battle Copter max level by Builder Hall: BH8 25, BH9 30, BH10 35.
| Builder Hall | Max level | Upgrades added | Step cost | Step time | Cumulative cost | Cumulative time |
|---|---|---|---|---|---|---|
| BH8 | 25 | 10 | 30,500,000 | 50d | 30,500,000 | 50d |
| BH9 | 30 | 5 | 19,000,000 | 30d | 49,500,000 | 80d |
| BH10 | 35 | 5 | 21,500,000 | 35d | 71,000,000 | 115d |
The 2,500,000 Builder Elixir unlock gives you a level 15 Copter straight away. There is no level 1 to 14.
From level 16, every Copter level costs exactly what the same Battle Machine level costs. From level 21 the time matches too; levels 16 to 20 take 5 days each on the Copter instead of 4.
When you use Bomb Rush, the Copter recovers health, dives at its target and drops a bomb that hits everything in the splash area. It is active from level 15 and moves up one ability level at levels 20, 25, 30 and 35.
The ability charges while you wait. Every deployment starts at charge 1, and each extra tier takes about 14 seconds. The splash grows from 0.5 tiles to 2 tiles to 4 tiles. At ability level 5, charge 3 heals three times as much as charge 1 (1,950 vs 650) and the bomb does about twice the damage (655 vs 319).
| Ability level | Charge 1: damage / heal (0.5 tiles) | Charge 2: damage / heal (2 tiles) | Charge 3: damage / heal (4 tiles) |
|---|---|---|---|
| 1 (LV15) | 179 / 550 | 274 / 1,100 | 368 / 1,650 |
| 2 (LV20) | 209 / 575 | 320 / 1,150 | 430 / 1,725 |
| 3 (LV25) | 239 / 600 | 365 / 1,200 | 491 / 1,800 |
| 4 (LV30) | 279 / 625 | 426 / 1,250 | 573 / 1,875 |
| 5 (LV35) | 319 / 650 | 487 / 1,300 | 655 / 1,950 |
Damage is for one bomb, not per second. Figures from the Clash of Clans Wiki.
From level 26 the two heroes cost exactly the same per level: 19,000,000 Builder Elixir and 30 days for the BH9 step (25 to 30) and 21,500,000 and 35 days for the BH10 step (30 to 35).
| At level 35 | Battle Copter | Battle Machine |
|---|---|---|
| Hitpoints | 3,456 | 5,380 |
| Damage per second | 193 | 290 |
| Targets | Ground and air, 7 tiles | Ground, melee |
| Best heal (charge 3) | 1,950 | 3,300 |
The Copter flies, so ground traps and ground-only defenses cannot hit it, and it attacks from 7 tiles. The Battle Machine has more health, more damage and the bigger heal. Upgrade the one you take into most attacks first.
The Clash of Clans Wiki notes that B.O.B Control level 5 needs the Battle Machine and Battle Copter at a combined 45 levels. Unlocking the Copter counts as 15 of them, so a level 30 Machine plus a new Copter is enough.
From Builder Hall 6, Builder Base battles run in two stages, and you pick one hero machine for each. The Copter joins that choice once you unlock it at Builder Hall 8. Supercell's rules:
On Dark Knight #82GY00YYQ my Battle Copter is level 22 at Builder Hall 10, while my Battle Machine is already maxed at 35. Getting the Copter from 22 to 35 will take 50,700,000 Builder Elixir and 80 days. The Copter is generally come into action once my primary Hero in Battle Machine runs out of health. The Copter's Bomb RUsh (Level 2) is the highest I've achieved so far. Therefore, I plan to upgrade the Copter next up.
Builder Elixir, upgrade time, Builder Hall needed and Bomb Rush level for each level. Level 15 is the unlock; no build time is listed for it.

Yes. It flies and attacks both ground and air targets from 7 tiles.
