On to the lower bracing wires & done. Dismantled the main gear, cut out the attachment hardware, soldered all the appropriate pieces & have it all installed. Now it's on the motor installation, cutting the holes in the cowl & hopefully that should do it & start covering.

I have one suggestion for you. You are using a push/pull system for your rudder. Used that method in a competition pattern ship and it always need adjustment. Problem is wire is under tension and all you need is a temp change(model sit in 100 degree sun out at field and wire lengthens given you slop in the movement on the servo.(that could even lead to flutter). Try it when it is 40 degrees when the wire contracts( it can bind the servo). If your can still get the CG right, move the servo back and use the same method(ball joint) as the elevators.

One of my co-workers was Bob Granville and he was always a pleasure to talk to(quite the stories he told). He was one of the 2 instructors who taught me how to fly RC. Even my son had him when he learned.

Yes U R correct. I have several birds with it & do need to adjust them from time to time. I like the way they look & having fun experimenting with them. Now that I am finally back up to building again, I need to get back & finish this one. I'm sure Bob had quite of few of very interesting stories to tell.

Very impressive build!! Any more updates?
I built a smaller version a few years ago from a free plan in the much missed Scale Model magazine in the UK designed by a guy named Dave Stirchley. It was powered by the lovely OS 26FS and flew pretty well on its maiden until an overheating motor quit in a banked turn an she stalled in.
I liked it enough to consider a larger version and I am in the process of tracing the same plan as you into Draftsight and scaling it to 60 inch span. Looking around online for some reference photos had me come across this thread, which has been very informative, so thanks for sharing your build.

OMG! I luv those colors. I want to finish this one in fabric. So, unless I paint, it will most likely be either in blue on white or red on white. Unfortunately I have no updates as of yet. Moved in into a new place a year ago & I am just now starting on setting up the new workshop this week. Look for updates after the first of the year. Post your build when U get to it.
