If you’re an RC enthusiast looking to step up from a beginner trainer to a thrilling warbird, the Ki84 WWII Fighter 690mm RC Plane might just be your perfect match. I recently unboxed, assembled, and tested this Japanese warbird replica, and here’s my honest take on its performance, features, and value.
First Impressions & Unboxing
The Ki84 arrives Ready-to-Fly (RTF), packed with everything you need: a 2S 1300mAh LiPo battery (yes, two batteries included!), SBUS/GPS expansion support, landing gear, a sleek white transmitter, and durable EPP foam construction. The 690mm wingspan strikes a balance between portability and presence, while the plastic-reinforced nose and magnetic canopy add thoughtful design touches.
What stood out immediately was the brushless 2204 KV motor paired with a drone-style prop—a clever choice for easy replacements. The included transmitter, with its retro-modern design and unmarked switches (more on that later), felt sturdy, though I’d recommend labeling the flight mode switches for clarity.
Assembly: Simplicity at Its Best
Assembly took under 15 minutes—perfect for pilots who want to fly, not fiddle. The horizontal and vertical stabilizers slot into pre-marked holes, secured by uniform screws. The wings attach via two plugs and screws, with pre-installed aileron servos.
Pro tip: Always perform a control check before flight! I verified the ailerons, elevator, and rudder responses, ensuring the brown/red/yellow wires matched the receiver ports. The landing gear snapped into place effortlessly, though the rear wheel required a firm push.
Flight Test: Stability Meets Aerobatics
I tested the Ki84 at a new field near Maitland, NSW, battling post-storm winds. Here’s how it performed:
6G Stabilization Mode (Beginner-Friendly)
-
Takeoff: Smooth ground roll with slight elevator sensitivity. Trim adjustments neutralized the dive tendency.
-
Flight: Stable even in light crosswinds. At half throttle, it cruised gracefully, ideal for scale flying.
-
Landing: The gyro-assisted touchdown was forgiving, though crosswind landings demanded extra focus.
3D Mode (Intermediate Agility)
Switching to 3D mode unlocked loops and mild aerobatics. The roll rate felt slower than expected, but snaps and dives were responsive. The 2S battery delivered surprising punch, though high rates proved overly twitchy for my taste.
Manual Mode (Advanced Control)
Out of stabilization, the Ki84 revealed its raw character. Knife-edge attempts were tricky, but loops and low passes felt crisp. The 300–500m range held strong, and the 20-minute flight time (per battery) matched claims.
