I too have just purchased a H9 Edge 540. I am thinking of using a Saito 180 or a OS 160 2 stroke. Which do you guys think would be better. I am leaning toward the Saito. I will be using Hitec 605BB servos for the control surfaces and a Hitec 422 for the throttle. Using a Klett 1/4 scale tail wheel assembly in place of the stock one.
Cajuncharley let me know how your servo mounting worked out. I am also thinking of doing the same thing.
