Lamar, to answer your question, yes the 4 star's do pitch down when rudder is applied. It's a aerodynamic trait or flaw they have. Moving the cg reward will make it pitch less but be careful it can get pretty snap happy moved much behind the main spar. I just put a rudder to elevator mix to balance out the yaw/pitch coupling.
Mine is shown earlier in this thread with Bob Hoovers Rockwell International theme. It is clipped 1 bay per wing and I cut the dihedral in half. I also added a dorsal fin. It fly's great. It's had a 46ax with macs pipe MA 11x8 @ 13,5rpm that made it unreal in the air. Now she sports an OS 52 4 stroke. I've been flying a MA K series 12x6 and really like this combo.
As to the clipping the wing and mods. I like it clipped. It really didn't seem to have much affect on the speed of landing just made it easier to settle in with out that float float all the way down the runway if you hadn't bleed the speed down. It still comes in really slow and gentle. My mods also made it track and roll a lot better. The dorsal fin helps with any tail wag and makes it knife edge better.
I did put a couple lite ply gusset plates in the fuse behind the wing saddle. And put scab plates running up in the nose on the lg block with the blind nuts on top of them. I had trouble with those two areas on my first. It was also my first low wing too so I was a little rough on it.
Skyraider/Breeze, Thanks for putting up this build. I enjoyed looking thru it and remembering building my 2nd one that I still have. Kinda funny but I think I have the same left wing, a tail, and the LG from my 1st. I've long said when this one gets rekitted I'll have a 3rd kit on order that night and have #3 rtf in a couple weeks. I love this plane that much. Here it is with the pipe next to my BTE Flyin' King.
