i am getting a area 51 in the morning, how well do they start< and what fule mix should i use, it is a used eng and I am sure it was broke in right, but this will be my first jc eng and I am not to sure how they run, I am putting it on my 27% extra, its about 15 or so lbs, I have a 20 by 8 prop to use but not sure if it will get the rpms i need, i would like to get this plane in a hover at 50% th, and have the other 50 to jet out if need be, any one with this eng have any good words for this eng or problems about it?
