I am presently building an Escapade, which is essentually the same as the Highlander. I will admit that my devotion to the project has been very lax, but things like a job, motorcycle, a Cherokee 160, just to name a few, have taken a bite out of my time.
Have you visited the factory and flown their demonstrator? That should be your first step. Just Aircraft has a very impressive operation and they always welcome guests. The Highlander is not a fast a/c but it excels in STOL /low and slow flying, and does a beautifull job of it. If you're into high speed cross country flying consider an RV. Fly a Highlander and see for yourself what a nice flying a/c it is, and you will be hooked.
The build manual is somewhat vague in a few areas, but the great customer service more than makes up for it. Jak, the customer service guy,and owner Troy have been a great help and always answered all questions to my satisfaction. These guys are more than willing to help. Your proximity to J.A. is also a big plus. It would be no big deal to drive over to see any specific areas that need clairification.
All of the materials and workmanship in the kit are first rate so go over to Walhalla and and take a look.
