Signing on. I spent nine months building a BUSA 1/4 scale DR-1 and would love to do the Spad someday. Lots of building isn't it? I think I took almost a month off in the middle of building mine simply because I got tired of building wings....wings...wings...I'd wake up in the middle of the night from wingmares.
I know I have at least $100 worth of glue in that thing.
I did a lot of reinforcements, also. I shear webbed the bottom and center wings, beefed up all the TEs, and lined the inside of the stab and elevator with 1/4 inch spruce, as the original design was way too flimsy. I went to 1/4" wire on the axle, and gusseted the aft fuse at each joint, as it was very flexible.
I put in at least 4 degrees right and downthrust, about 3 degrees positive incidence on the stab, and counter torque weighted the right hand wing tip. (1.20 engine times 2 = 2.4 oz in the tip)
All of this resulted in a very scale flying, well behaved airplane.
Build looks very nice. Keep truckin.
