I finally got to run in my 75s today.  I left the timing marks as I last posted.  I used an APC 11x8 prop and 30% cool power heli fuel.  First tank was slobbering rich but I couldn't get it below 5K rpm.  It ran about 7K.  let it cool. 2nd tank.  Ran it about 8.5K. Cool down.  3rd tank 9.8K. Cool down. 4th tank 10.9K.  Idles as low as 2200 and accelerates with no hesitation.  I will pull the cam cover and check for lubrication later this evening and post results.  I am ready to fly it.  I just need to put it in an airframe and should be able to fly by Friday.   Estradajae  thanks for your input on the cam lube.  I had a few drops coming out the front brg during the runs but not excessive.
