The 1818 is for Q S and T sport hydros in two lap or oval trim but Im at a Delima with these aspect ratios and the straight shaft angle in Finlay plans. Its 6 %. A 6 degree angle of attack on this prop only promotes more lift and drag. I have a long 1/8 wire drive but I dont know if id want to put a bend in it to set a strut AOA of zero degrees. I dont see the need to add lift to these props in AOA setup. I may switch to 1/4 inch flex but I really didn't want to do that. I guess id accept 3 degrees in a straight shaft setup. I really need articulated ball pin universals to take advantage or straight shafts but I think that's a stretch at 90000. For a 30000 rpm something can be built of the lathe.
