That's amazing work guys 
It fascinates me to think of the scale speeds these planes reach. Wikipedia says a Bearcat has a wingspan of 10.92m, a max speed of 678km/h, and a takeoff weight of 4,354kg. That makes RC rarebears approximately 1:20 scale, given their 620mm wingspan.
20 cubed is 8000, so the scale weight of an RC rarebear would be around 2760kg, which means its a little less dense than the real thing (perhaps they should build the full-sized ones out of foam!).
However, if an RC rarebear goes 200km/h, I think it's achieving almost SIX times the scale speed of the full-sized version!
(20 x 200) / 678 = ~5.9
Does that make sense? To fly "scale" an RC rarebear should be going approximately 34 km/h, not 200km/h? Or to look at it from the other angle, an RC rarebear would be six times as exciting to ride in (FPV!)
