Thanks for the information. You are right about them being crashed. I found this one in a dumpster and rescued it. I put it on the rack in my shop and about 3 weeks ago I rebuilt the 2 piece aluminum landing gear and the front of the fuselage. I had little or nothing to go on. I did some calculations on the CG and it is real close to what is specified on there web site for the CAP21. Thanks for the help.
