This method was shaped by the kind of RC pilot I used to be: curious, hands-on, learning by doing. It comes from years of flying, crashing, scratch-building, and correcting mistakes the hard way.
It is written for thoughtful pilots and creative builders tired of vague rules, messy plans, and airplanes that look right but don’t fly right.
Most RC airplanes do not fail because of bad calculations.
They fail because key decisions were made too late, or in the wrong order.
A wing is sized before its mission is clear.
Balance is adjusted after the first crash.
Numbers compensate for choices that were never explicitly defined.
This book follows a different sequence.
It is a decision-first method for designing RC airplanes, turning mission and aerodynamic logic into clear, build-ready specifications aligned with your intent.
Mission defines direction. Geometry expresses it. Numbers specify geometry. When that order is respected, calculations support the airplane instead of trying to rescue it.
This is not about turning you into an engineer. It is about learning how to think like a designer.
Order before detail
Every design begins by defining what the airplane is meant to do. The mission becomes explicit in the next chapter, setting direction for all major choices and preventing the project from drifting.
Instead of relying on rules of thumb, aerodynamic logic is applied directly. Lift, drag, and moments explain why the wing, tail, and fuselage take the shapes they do in practical terms.
Before the first flight, size, balance, and proportions are defined deliberately so the airplane behaves as expected, rather than being corrected afterward.
Airplane design offers endless variation. That freedom is part of its appeal, but it can delay clarity. Without structure, it is easy to revisit a planform, reconsider a proportion, or postpone a compromise until the design becomes difficult to build, difficult to fly, or difficult to understand.
Structure prevents that drift. It avoids dead ends while preserving creative control.
Each chapter resolves one design question before introducing the next. The sequence matters because decisions depend on one another.
Before moving into missions and geometry, we establish a shared baseline. The next page revisits the fundamental control axes and forces that act on the airplane to align vocabulary and physical understanding.
With that alignment in place, the design process can unfold naturally, one decision at a time.
RC Plane Designer evolves as chapters are refined and connected.
The project began as a personal notebook used while designing scratch-built RC airplanes.
