WOW this is so coincidental. I have the same airplane but the Yellow and Blue trim. I bought mine about 5 yrs ago and its still sitting in my home office unbuilt. I kept looking at it and thinking when I am going to build it.

Just last night I was online looking for Dave Patricks website and realized he is no longer in business, that's too bad because he designed and made some really great airplanes including this edge.
Dave Patrick is Canadian born and used to fly at our club when he was a teen, in fact the guy who taught him to fly still flies with us and a friend of mine. Dave went on to win the Pattern Championships more than once I think and had bought over Carl Goldberg Products.

I think what killed his business is when the era of 3D flying came into being and the market was flooded with 3D airplanes, none of which he was manufacturing at the time. The Edge would have been a half decent 3D airplane but with introduction of the Extreme Flight first generation YAK 54, they stole the 3D market along with Great Planes Patty Wagstaff Extra 300L

I have bought over $500 bucks in Hitec Digital high torque servos for this airplane and have a DA50 waiting for it, but was contemplating building it or not. Its such a beautiful airplane, but the EF YAK 88 also got my attention years ago.

The tail stab aluminum I am sure will be easy to fine in CA, just look for an aluminum or metal supplier or look for a scrap metal company. If you have trouble getting it I can get it here for you easily but I am in Canada, you should not have to go that far for it though.

I am happy you are building yours, please keep the thread updated with your progress, who knows I might build mine too soon.
