I am going with 2 servos for the ailerons and 2 for the flaps for the security, I am thinking I want max control for this over powered bird.
I am not sure about the zenoah I have not actually seen one in person , the BCMA also has E.I. and is pretty light for a gas engine I am using a rear dump muffler to keep things in the cowl and the scale look the only major hole I am planning is for the side draft carb.
