That profile looks great AeroDave you must have rocketlike pullout at that wieght, i will use the 90 degree adaptor it should fit good inside of the cowl, i hope to have good pullout with that engine in the 100X, i am flying a GP U-CAN-DO with a os surpass 70 and pullout the plane with autority not to slow and not to fast but i would like to have a bit more pullout performance on the 100X
