high in da sky,

My dad and i had the same problem. First, we had to Turn the engine mount right side up on the plane instead of upside down which it was suppose to be mounted. After that, we put some 1/2 in. carbon blocks under the engine and kept the engine inverted. I'll try to post some pics later or tomorrow. We tried to raise the engine up as high as we could and it is still a quarter in. below the middle of the tank. When i post some pictures, it will give you a better discription. The engine has run fine since.
