The new aerobat by Karis (sp) - is -strangely enough -- in the new March issue of RC Modeler - I don't remember the page number -
He was a top Sukhoi pilot and this is his "shot " at an even hotter setup --
The Pitts setup to provide a predictable stall- -wasn't that back in the late 40's? Betty Skeltons Stinker? (early 50's)
current aerobats have a rather (ahem) more aggressive performance arrangement.
