Quickie 100 RC flight video

I managed to shot a vid today on the Quickie 100 Racer, with the 1974 red postage stamp back-plate COX 049 reedie in its nose, beefed up with a Kamtechnik turbo head, and spinning a APC 4.5 x 3.5 prop. Fuel is 60/20/20 all-castor..Sunny day, air temperature a tad below 10 Celsius, Northern winds. Couple of people walking their dogs nearby, so my flight path was rather limited...(March 15th is a National Holiday in Hungary, but rallies in Budapest and all cities were canceled because of COVID19 concerns, people came to the field instead to enjoy the spring sunshine)



The plane is very quick and does all the aerobatics an amateur like myself can and wants to do, from loops, cork screw spins (sorry if my terminology is not correct), wing-overs etc.  

I audio-tached the video and measured engine speeds well above 24k incoming and outgoing passes both (i.e. Doppler or not, the engine unloads faster than 24k). This puts the theoretical speed of the plane - calculated from the prop pitch and rpm - to around 130...145 km/h and makes the Quickie 100 the 2nd quickest plane - after the TeeDeeVooDoo - that I have ever flown.

Also, the theory of copper reed valves tending to float and limit COX engine speeds below 20k does not seem to hold.
