Some design changes are due to the fact that this airframe was started by another builder who made changes yet some are done for reasons explained below. If you have other suggested modifications feel free to chime in with a 'short' note or link pointing to another thread.
1st: as I understand it, the original builder tacked up the bottom fuselage on a table made from a set of doors too narrow to allow the full width of 24" so the width was set at 21". I'm not a big guy and this is an XL so I think 21" will be great.
2nd: Based upon information from other builders (ie. Chuck), the Verner 3VLA is a bit weighty and makes for a forward CG if mounted in the standard 1/2 VW location. It was suggested I move the firewall back "a few" inches. So that is what I'm doing, moving it back from 24 1/2" to 22 1/2" from STN#2.
3rd: Also based upon recomendations with the Verner 3V. Some have mounted the 3V up 3" from normal VW location. This puts the engine noticably above the firewall. So I decided to make the firewall a square 13.5 x 13.5" instead of 13.5 x 11.5.
