JACKALL,

Go to "search" and type in engine break in, This subject comes up consistantly (MARC, COULD WE DO A FORUM ON JUST THIS SUBJECT?) I do not believe in breaking in, in the air!! you have absolutely NO CONTROL! you need a smaller sized prop to keep the revs high (but not rediculous) and do not let the engine get hot. Somewhere here I posted DUB JETT's engine break in techniques.. Go to his web site and read read read..... And do all of your break-in test work on a test stand..... Have it broken in when you're ready to fly..
