Schultzie,
I love the pictures, but Dawn is not in all three pictures.
And again. how well did you Sting Rays turn?
You are right about only the first photo with Dawn holding my Ray. In those early days...I was always asking young ladies if I they would HOLD MY---- stunt models for pictures.
My first Sting Ray was a REAL LEARNING EXPERIENCE...With the Merco 35 and a 4 ounce tank...AT FIRST I lived with a NOSE HEAVY model with too much tip weight and engine offset.
but after a couple of months and razzing phone calls to Bob!
MORE THAN A COUPLE OF TIMES I ALMOST LOST THAT MODEL ON THE BACK BOTTOM CORNERS OF BOTH THE HOUR GLASS AND TRIANGE.
I finally MANNED UP and took out that excessive nose weight...reduced the wing tip weight..however l did leave in the slight amount of engine offset.
NEXT IS THE STRANGE PART!! WHAT A HUGE DIFFERENCE A PHONE CALL TO GIALDINI CAN MAKE.
After I FINALLY RETRAINED MY MUSCLE MEMORY AND RE PROGRAMMED MY BRAIN... and got used to a model that flew with less line pull
without all that excessive wing tip weight and engine offset...NOT ONLY THE INSIDE CORNERS SHARPENED UP...without all that line pull and wing wobbling...The Sting Rays were the easiest and smoothest flying models that I ever experienced before. I was hooked.
THE STAB AND ELEVATOR although on the small size...STILL SEEMED TO HAVE PLENTY OF TURNING CAPABILITY! Sadly...it took almost 4 years of building and flying the Sting Rays, plus took me THAT LONG too finally finding and LEARNING the perfect combination in trimming.
Like so many stunt designs...it takes lots of living and airtime with a model in order to find what the flyer is looking for in a model.
Yes!
In my Avenger series...I utilized a sub dorsal fin to increase side are behind the CG fuselage at the same time aided stiffness to a
larger stab and elevator combination. which perhaps aided in a tad more line tension?
Not only did I come up with more wing area but also more turning power...but now with a tad more power using a new OS 40 Wilder tweaked engine...my building techniques also kept the weight under 47 ounce flying weight with a 4 ounce tank. (barely enough time for a pattern on my traditional 68 ft ALL AND FOREVER MOST IMPORTANT.O15 lines
Without the grace of being a member of THE ROBERT GIALDINI'S SCHOOL OF FLIGHT...These beautiful Sting Rays of mine as well as my Avenger would never have been possible.
eEVEN IF ONE NEVER BUILDS A GIALDINI STING RAY I STILL STRONGLY ENCOURAGE EVERYONE TO DIG THROUGH THOSE OLD MAGAZINE ARTICLES THAT BOB GIALDINI SHARED WITH US....HE HAD SO MANY GOLDEN WORDS OF ADVICE THAT I THINK ARE A GOLDEN TODAY..AS THEY WERE WAAAAY BACK in his Olympic Mark daze days.
