donhef,

I am currently building this kit as well but I'm not quite as far along as you are. I can't say that I have any suggestions but I would love to hear what other's say in response to this. I agree there aren't many threads here on the Dreamer. It's an old kit that not too many people know about or have ever built. I've come across about three people on here that have built it. I too have a question for the aileron servo. I think I want to use two servos but like you I don't know whether to mount them upright or upside down. The servo will have to be very low profile to fit in the wing and have the arm line up with the holes in the wing ribs. As for the other three servos, I think you have it right. The fuel tank will go between the engine bulkhead and the next bulkhead and the servos should mount in the space above the lower wing opening. I think they will mount with the servo shaft facing down. That way you can access them once the plane is completed.
This is my second plane, I built the 4*40 as my first one and I can't imagine building the Dreamer as a first one. You are pretty gutsy. It is very difficult without having building experience. Sounds like you are doing pretty good though.
Did you use the interplane struts in the wings? My instructions said that they are not functional on this plane so I left them out but I have hard time believing that they aren't functional.
I am very interested to see what people say about this stuff.
