It's a shame that the classic cut off date is 12/31/1969. I'd build one if it was classic legal. Darn...
But Donne, you can still build a Stingray for classic. 
Yes...what a great n' beautiful stunter...designed by the best of the best....and what an elegant model in the air
...(landings were often quite exciting to say the least.) IF YOU DIDN'T LAND IT HOT...Bob designed the Sting Rays landing gears....to have a noticably small FOOT PRINT on the moment of contact with the ground.
Those long inward swept main landing gears worked to perfection with that rearward slanting nose wheel all worked together to make the cleanest wobble-free contact with the ground ....HOWEVER IT LOVED TO AND HAD TO BE ALWAYS LANDED HOT WITH LOTS OF AIRSPEED.
When you touched down with good airspeed...IT WAS BEAUTIFUL AND VIRTUALLY IMPOSSIBLE to know exactly the moment of contact to the tarmac...
which natually would make for max landing points...Those inward slanted gears really absorbed the shock beautifully and talk about beautiful ground contact with NO BOBBLE OR BOUNCE....
OOOPS!LOOOK OUT!
If you screwed up and missed the wind and try to flair and try to whip that dead stick model around for another go and found yourself out of air speed.
THEN YOU WERE IN DEEP POOO-POOOOOO.
Touch that Sting Ray down at too slow a speed and you were asking for that funny HIPPITY HOP off one main slanted gear...that would spring that wing tip up and back down on the other wing...and BONGITY BONKITY back again to the other side. BINGITY-BONKITY BACK N' FORTH.
I think our beloved stunt judge... Bob Parker counted one of my touch downs...and totaled me about 6 landings on that one landing.
How alarmingly and weirdly funny to watch that Sting Ray spring gear do that funny little dance-- I SAY AGAIN....
SO THE MORAL OF THAT TRIKE GEAR DESIGN (WITH THE NARROW FOOTPRINT) WAS TO SIMPLY KEEP THE AIRSPEED UP..AND SET IT DOWN
HOT-HOT-HOT!The rest of the flight with a Sting Ray was truly soooo smooth and predictable..UNLESS YOU REALLY OVER HAMMERED THAT BACK BOTTOM CORNER OF THE HOURGLASS...
On my first Sting Ray....I think I might have had a problem with air pocket blanketing from that wing. Which would block some the airflow to the elevators??? I am NO AERODYNAMISTICAL' ENGINEER LIKE GARY LETSINGER? However in most situations..this was never a problem...except in really high wind conditions?
