Mount the turbine to the rails as they are supplied. Then line the tube up to the turbine ( Straight ) All is fine. The heat is distributed evenly down the pipe ( Dont worry this is no fry eagle pipe

) There is no pitch change with power. I know it looks strange but all of the Vipers are like this and all work perfectly.

Ali,
with a friend of mine that is building another Viper we measured the difference of degree between wing and engine mount... 4 degrees!!!
Of course I swear I believe you (!!

) about the strange absense of pitch change with power but what about the total power? Don't you think we can lose some of it?
