Hey Phildo,
As I scratch-built mine some 14 years ago, I found it easy to get some supplies here in Oz. I was extremely lucky to find Brad Waldron in Castlemaine Vic, who was an artist in cutting the timbers from gigantic logs of Spruce ( and if you have seen the plans there is quite a lot of small cut timber in the wings).
These days, I dont know what Brad is doing, so my suggestion would be the mini kits. I did purchase a couple from Wayne Ison when it was the TEAM Inc MiniMax, and they were very well produced and relatively easy to ft into my aircraft.
I built from the 1100R plans set, but it was an older set of plans and the width of the fuselage was 22inches, where the newer models are 24 inches. I had to re-work the rear turtle deck just a little to get it to fit, but as you can see, it does and quite well.
Still the best little aircraft I have ever flown and more than worth the 2 1/2 years build time.
The ONLY problem I have ever had with this arcraft, is that on landing, those huge wings tend to blanket the rudder thus you can turn into a go-kart real quick, so we have to fly it onto the ground and hold the tail off the ground until it stalls. By this time the speed has washed off and the tailwheel allows decent steerage.
Hope this helps some and if you need any help, just drop in a new quote here or contat me through the membrs messages.
Cheers ( it is worth the build )
