<DIV>Jerry,</DIV>
<DIV>I had a similar situation, a few years back, on my first pattern plane, a used Excelsior 2M that I bought in the UK. The stab had been glassed and painted. To make CG it needed nearly 12 oz in the nose. I changed the stab for a monokote covered version and saved over 3oz and was able to take out all that nose weight, and saved nearly a pound overall ! </DIV>
<DIV>I that is your only alternative, itīs worth it.</DIV>

Maybe you are using the wrong CG point or did you<BR>put servos in the tail? Is the tail painted. I think figure out why, then<BR>solve the problem that way instead of adding all that weight.?<BR><BR>Jim Ivey> <BR>> From: "Jerry Wilson" <JWILSONJR@HOUSTON.RR.COM><BR>> Date: 2005/06/29 Wed AM 07:14:53 EDT<BR>> To: <DISCUSSION@NSRCA.ORG><BR>> Subject: Elan trouble<BR>> <BR>> I have a dilemma and could use some advice from the group.<BR>> <BR>> <BR>> <BR>> After over a year of building I have nearly completed my Elan which is my<BR>> first attempt to build a fiberglass fuse pattern ship.
