For some reason I stumbled across this site this morning and saw the Grid Leaks information. It brought back a memories of time spent memorizing them

My older Brother, James Lanterman (Butch), and I used them as a guide to understanding R/C and we spent hours building our equipment based on what we read in them. I designed a ground effect machine that used pulsed rudder only for control based on Grid Leaks information.
My Brother went to work at World Engines in RC design for a number of years after graduation from Purdue, and I graduated as an Aero Engineer from Purdue working for McDonnell Douglas helping design the F-15, etc.
Grid Leaks guided our formative years and I thank Paul Runge for that. I am 71 and I am flying every day that the weather (and arthritis) permits. Now after I have flown with my new shiny JR-12x, I will read a Grid Leaks magazine to get a comparison with. I'll think about the good old days
Good Flying to all,
Ben Lanterman
