RC Plane

This tower circles its base and pops bloons with its propellor. It has quite a few... interesting upgrades, and even becomes stealthy, too! Cost: $970 (Cannot pop camo or lead bloons without upgrades.)

Path I

 * Autonomous Targeting: Enables the Autonomous mode, which allows the RC Plane to lock onto bloons and chase them down. (Returns to base if target is popped. Autonomous Targeting acts like it is on Close Priority targeting mode used by stationary towers.) Cost: $510
 * High-Power Motor: This heavy-duty motor makes the prop spin so fast, it pops lead bloons! Cost: $385
 * Combat Drone: A super hi-tech drone that fires special homing missiles that can pop black and zebra bloons as well as lead bloons. (Removes the ability to pop bloons with the propellor.) Cost: $1350
 * Reaper Drone: The deadliest combat drone known to exist ever is in your hands! This one fires, in addition to the homing missiles, laser-guided bombs that do heavy damage to ceramic bloons, and special NEW homing missiles that pop as many as FIVE layers of bloon! Ouch! (Neither one of the new attacks pops black and zebra bloons.) Cost: $6800

Path II

 * Advanced Chopping: The rotor is now so efficient, it can rip the regen status right off of bloons it hits! Cost: $770
 * Surveillance Drone: Allows for the RC to spot camo bloons. Doesn't grant camo detection to nearby towers... yet. Cost: $260
 * Advanced Intel Channels: The RC now gives towers that it passes over in its flight path camo detection. Cost: $1500
 * The Beast: A mysterious surveillance drone has been added to your defences. It is stealthy, and sucks bloons into its turbofan engine instead of popping them with the rotor. (Grants Stealth status to the RC Plane, in addition to turning it into a flying 1-2 Bloonchipper) Cost: $4250

Trivia

 * This is my first tower to NOT have an ability.
 * The Combat Drone upgrade is a reference to the real-world MQ-1 Predator.
 * The next upgrade is a reference to another real-world attack drone, the MQ-9 Reaper.
 * The Beast is a reference to ANOTHER real drone (this one is a surveillance drone), the RQ-170 Sentinel (AKA: The Beast of Khanadar).
