Is anyone in the group flyng an "A" powered Piet using the Bumfield Standard head (cast iron, 5.9-1 compression...not the Super head) or know anyone who is. I just wanted to get some idea about its good or bad points. I' m not really interested in the aluminum heads with less weight and higher compression that are currently on the market Don Hicks________________________________________________________________________________

Jim Hammond of Yellow Springs, OH flies one. it was upat oshkosh this year. he slapped it an because thealuminum head cracked. he gets no rpm or horsepower. it is not reccomended. his air camper is single seatuntil he gets a new head. he told me that he plans tobuy a new aluminum head and mill it out to 5.9/1.hope that helps you out.Dan BadgerIHA#111 --- DonanClara(at)aol.com wrote:> Is anyone in the group flyng an "A" powered Piet> using the Bumfield Standard > head (cast iron, 5.9-1 compression...not the Super> head) or know anyone who > is.
