Hi Don
My plane #31 is finished and flying. So I cant give you raw weight but my
AUW is 61 oz. Originally with the plane balanced at Drelas recommended CG
(92 mm) it took 4 3/4 oz added to the nose making the AUW of the plane 62
3/4 oz. By final set up (dive test and more dive test) I removed 1 3/4 oz
to get the plane to fly like a want a TD ship to fly. I could be wrong but
I believe the 92 mm CG is more of a European F3J set up.
Just my opinion but what a plane at 61 oz.
Maurice

Subject: [RCSE] Molded Supra Raw Weights
This message is directed to a small group of new molded supra owners, and
probably not of interest to other.
I have an excel spread sheet I would be happy to send to any other Molded
Supra owner who has not yet started assembly of their newly arrived
"baby".
I only ask that you weight all the raw kit parts and add your weights to
the
sheet and return the sheet to me.
I am not a weight weenie, but I started this exercise to try and determine
a
couple of things. First thing I was curious about was the exact weight
difference between the carbon wing lay-up and the standard wing lay-up.
Barry talked around it and didn't give a precise answer. The next thing, I
am trying to understand why some people are talking about having to add on
the order of 4 oz of nose weight to balance. Was this due to variations in
fin, stab, boom, or pod weights, or is this inherent to the molded design?
What have I found out so far with raw weights from 2 planes (#34 and #48),
left and right wing tips and joiners are VERY equal in weight - good.
Besides the type of wing lay-up, the most variation in weight has shown up
in the tail boom. One boom weighed 63g and the other 73g, on the order of
a
15% variation and who wants extra weight aft of the cg.
