MICRO - Center of Gravity (fuselage)?

[Stephen]

For stability calculations empinnage people need to know where the
center of gravity has been designed. fyi the battery, reciever, and 2
servos will be inside the tail about 18 inches from where the end of
the I-beam is.

emp is using two of these

to attach onto the inside of the I-beam on each side parrallel to the
web. Just double checkin with you to make sure this works.

plane only using one reciever. we are designing the tail to hold this
extra weight so we can get the center of gravity as close to where its
supposed to be (just behind the wing center of lift at takeoff angle
of attack) so that there is less chance that we'll mess up with center
of gravity during construction or when we are adding weights at
competition.

But your right we can do the exact cofg calc later. Right now Im just
wanting to know roughly +- 1 inch where the cofg will be and where the
end of your I-beam (the only i-beam) will be. Do you or somebody else
have a sketch or solidmodel you can through onto google groups?
