I hope this isnt wrong, I talked to many of the flyers and questioned them on the Powerplants Used, If anyone disagree's please make the correct changes.
Another "interesting" Point to come out of the world champs is this :
Did anyone notice that 1st, 2nd and 3rd all used "radial cowl" style front ends, with regular propnut style snub spinner??
*scratches chin.. * coincidence?? maybe... Maybe not....
Outside triangles?
