The real A6M5 Zero has a wingspan of 36 feet 2 inches and a length of 29 feet 9 inches. Let's convert these to inches and do some simple algebra:

36 feet 2 inches = 434 inches
29 feet 9 inches = 357 inches

434/62.2 = 357/x

where x in the equation above is how long the VQ Zero should be.

x = (62.2 * 357) / 434 = 51.2 inches

So, if the Zero was true to scale, then it should have been around 51 inches in length. Mine is around 44.2 inches from the rear tip of the fuselage to the tip of the spinner. VQ labels the Zero as "Semi-Scale", so I can't really complain. However, it would fly much nicer and be more stable if the fuselage was longer (longer tail moment).

If the tail was longer, then you would need to add more weight to the nose to balance the plane since the tail would be more heavier. Perhaps this is why the plane has a short fuselage.

The Kyosho ME-109 flies and lands great. It's a floater on landing. You can just chop the throttle when it approaches the edge of the runway, and it will just gently glide in without tip stalling. It weighs only 6.5 pounds with a Saito 72 4-stroke up front. My Zero is 7 pounds 1.8 ounces and needs two or three clicks on the throttle to do a good landing.
