RGIGN1, Please don't take this the wrong but wouldn't a "more modern" engine work better for racing? Less weight, more power etc. It seems like they are preferred for acrobatics. Just curious
I seemed to remember there are some classes of racing that REQUIRED all planes to have a G-62. I thing they were all AT-6's IIRC.
A more modern engine would be lighter, but a scale plane would need the weight anyway (and often more.)
