My Feedback: (3)
I'm mounting a Moki 180 on my Hanger 9 1/4-scale Cap 232 and am wondering whether I'm setting it up correctly.
I'm using the engine mount that came with the kit; the engine is side-mounted in the rear-most position within the slots. The mount is bolted to the firewall, using the extremes of the stock holes due to the width of the engine crank case. This appears to be the optimum position EXCEPT!!!! The cowl does not appear to center virtically on the prop shaft. It is fine horizonatally and I can force the virtical position to center but I end up with the top of the cowl laying about 1/4" above the fuselage. This is caused by the firewall former, which when the cowl is fit over the front sits about halfway down its length -- I certainly don't want to modify the top of the firewall???? I could also offset the engine within the mount but am concerned I will dial in upthrust when downthrust is preferred. I might be able to raise the engine mount position relative to the firewall but there is very little room to work with due to the width of the engine crank case. THOUGHTS????
I am planning on running dual elevator servos and a 4-40 pull-pull rudder from one servo. What are my options for positioning these servos relative to establishing a good CG with this plane/engine combination? Where should I postion the throttle servo (under wing or within cowl???) I'm planning on running dual batteries and dual switches so I have their weight to use for CG corrections. If it will fit, I am also planning of installing a 24oz tank in the normal tank position. I could change this to the CG position if I can move the tail surface servos to the rear of the wing area or mount them on the tail because I am going to be running the Moki with a Cline Regulator.
