PC air duster motors power 21-inch DIY remote control plane at 130,000 RPM — $23 air duster power styrofoam A10 Warthog-style RC plane, hits the skies much faster than expected

PC air duster motors power 21-inch DIY remote control plane at 130,000 RPM — $23 air duster power styrofoam A10 Warthog-style RC plane, hits the skies much faster than expected

A remote-control hobbyist was taken aback by a model airplane they constructed, which was powered by a pair of PC air duster engines. The plane, resembling the A10 Warthog, boasted a 21-inch wingspan and performed "much faster than anticipated," according to RCMakerLab, the source of the video. The video features an informative display on building your own high-performance RC plane utilizing PC air duster motors, such as the 110,000 RPM brushless Wolfbox MF60, which is currently discounted on Amazon for $31.99.

The creator's video, inspired by earlier disassembly and testing of PC air duster engines, focuses on the twin-engine RC plane's assembly. The plane's wings were fashioned from a Styrofoam sheet, and the motorized wing flap control was particularly innovative. Fast forward to around 8 minutes into the 10-minute video to witness the installation of the two air blower motors, and at 9 minutes and 20 seconds, observe the plane's rapid takeoff.

With a 54cm (~21-inch) wingspan, 42.5cm (~17-inch) length, and 368g (~0.8 pounds) flight weight, the plane was estimated to fly for 3-4 minutes on a single charge. The cost-effective RC air duster jet specifications include twin airduster motors with a 20A Brushless ESC, 5g micro servos, a Flysky iA6 Radio Control FS2A Micro Receiver, 1,300mAh battery, and rechargeable handheld air dusters as power sources.
