Safebet,

I did enlarge my rudder a little bit but I didn't increase the height of mine. I just kinda added a little more angle to "sweep" it back some. I just didn't like the way the stock rudder looked.

I'm not positive as to which tank I'm going to use on mine yet it's still to early in the building process to tell for sure. I've got a 10 oz. Sullivan Flex Tank laying around and it looks like it'll work by the plans but then again I won't know for sure until the fuselage is built.

Every body have a safe Thanksgiving

Regards
Mike
