Yeah, I know. This plane looks like the parent company of the B-17 Flying Fortress, Boeing, decided to build a Reno Racing machine! But really, the Quadzilla was born from my desire for something totally different. I was thinking that everything had been done in RC: helis, jets, scale, pattern—even twin pattern models! So what haven’t I seen before? A four-motor sport pattern ship! This would be a nightmare with glow but easily accomplished with electric power. How to keep it simple? Inexpensive brushed motors would only require one speed control and relatively simple parallel wiring. So using my multi-motor experience and some basic parameters, I conceived Quadzilla with a 50-inch-span with a sheeted-foam wing and basic box-structure fuselage. It uses four Speed 400 or “long can” 480 motors, a single 45- to 55-amp speed control and a 3-cell, 3700mAh LiPo battery pack.

PRODUCT REVIEW: RC PLANE STANDS BENCHTOP MODEL
I’m a sucker for shop stuff. I buy tools I will probably never use just because they are cool, or I might need to use them someday. When Glen from RC Plane Stands reached out about a review, however, I knew as soon as I browsed their website that I would be receiving something I would use a lot, maybe even daily.
