Do you want to know how realistic our Beaver really is? Well, let’s do some math (don’t worry, it’ll be fun!). The original Beaver is built to 40% scale and the empty weight of the original Beaver is 1361 kg. If you scale this down (1361 kg/2.5³ or 1361 divided by 15.625), you arrive at an empty weight of 87.1 kg for the model Beaver. The prototype, however, tipped the scales at only 77 kg. When we checked the center of gravity it turned out that the aircraft was tail heavy and needed quite a bit of lead under the cowl—10 kg, to be exact. Let’s do some more math, shall we? The motor of the original Beaver, a Pratt & Whitney R-985 Wasp Jr. radial engine, weighs in at 300 kg. Scaled down to our 40% size, this engine would weigh 19.2 kg. But the Moki S400 weighs only 9 kg—there’s your missing 10 kg! Pretty incredible, don’t you think?
