Razor Rotor blades rip up Bloons on contact, including Lead and Frozen Bloons.
~ BTD6 description

Razor Rotors is the third upgrade of Path 1 for the Heli Pilot in BTD6. It allows the Heli Pilot's sharp rotors to hit bloons on contact, popping and dealing 2 damage every 0.75s. The Razor Rotor attack can also pop Lead Bloons and Frozen Bloons. Razor Rotors have 10 pierce per cycle in BTD6.

It costs $1,485 on Easy, $1,750 on Medium, $1,890 on Hard, and $2,100 on Impoppable.



Razor Rotors provides some extra grouped popping power that the Heli Pilot may tend to lack in its earlier upgrades. Compared to other anti-lead options, Razor Rotors is quite expensive, but with the extra damage buff in Version 24.0 it is quite effective as area-of-effect with mobility.


  • Razor Rotors is best used when not in Pursuit Mode. Instead, it is better off to micromanage the Heli Pilot by manually flying the Heli Pilot over the target bloons, especially Lead Bloons.
    • Compared to BTD5 Mobile, Pursuit Mode is not nearly as negative when paired with Razor Rotors. In BTD6, setting a Heli Pilot on Pursuit will make it follow just in front of the bloons.
  • Crosspathing does not benefit the Razor Rotors attack, with exception of 3-2-0 for camo detection. Use whatever crosspath helps the Heli Pilot's other attacks, or 3-2-0 for hitting Camo Leads.

Version History[]

The strength of Razor Rotors was initially similar to how it was in BTD5 when it was first released in BTD6. It was buffed later on to improve its blade reliability when interacting with Pursuit targeting, and gained extra damage to make it more worth the price as an area-of-effect with mobility.

[...] On the opposite end of the spectrum, Pursuit Razor Rotors has underperformed due to distancing itself far too much, so we increased the range of this attack slightly.

  • In BTD6, the Razor Rotors Heli Pilot will intentionally tilt towards the bloons to shred bloons. Similar behavior occurs for Apache Dartship and Apache Prime.
