Status: offline 		Have been doing some fiddling around this weekend. I was looking at the cooling vents for the wing. They look ok, but I think I will scale them up, give it some relief to make it look more realistic. I glued the alum spar to the plywood insert. This will slide into the wing, and is epoxied in place. Just checking for fit right now. The starboard wing was not cut deep enough so I needed to remove 5/16th of an inch for a proper fit. A hacksaw blade made this an easy task. I hope tomorrow I will have a little time to do at least one wing, just need to make sure it is aligned well, so the sheeting will be flush with the fibreglassed part when it is attached.

Just pluging along. I am trying to do at least one thing per night. Tonight I epoxied the spar into the port wing, and I plan on doing the starboard wing tomorrow.

Status: offline 		well I have just spent last 2 nights setting up our new Vista based PC and migrating all of our files, favourites, emails .dbx files etc etc

Thank goodness we have an ethernet hub and can network both boxes.

Just a few programs to install on the new one and I am done, then I can get back to building!

Status: offline 		Hi Craig,
Very nice build. I have had 5 of the Byron Corsairs and everyone flew great. Just a heads up. When you get to gluing on the stabs Byron only has a small spar piece at the trailing edge and the rest is butt glued to the fuse. This is a weak point and is prone to breaking or flutter. I glue in a 12 in. piece of 1/2 in. aluminum tubing that spans both stabs and is glued against the ply bulkhead where the tail retract goes. This makes the stab bullet proof with very little weight. In essence it's a front spar.
Just a thought. Good luck with the rest of your build.

Craig,
I don't mean to hijack this thread but I feel that Fred has a great suggestion and I needed some clarification. If others are building the same kit they may also have the same question; so I decided to post it rather than a pm.


Fred,
The Corsair I am finishing for my buddy had the stab already attached. After reading what you did, I would like to also do the same. However, the bulkhead that the tail retract unit mounts to is about 1 1/2 inches or so (I didn't measure it) in FRONT of the leading edge of the stab and the linkage for the rudder torque tube is on the AFT side of that former lwhich will impeed the aluminum tube. Did you add a couple blocks of wood glued to the bulkhead and then glue the aluminum tube to those blocks? Or am I missing something?

Thanks!

Les

Status: offline 		Great input. I was actualy reading the instructions for the horizontal stab this evening. I was concerned with the butt joint and only the 1/8 plywood at the rear tying it all together. The other issue that I was having was finishing the stab before I attached it. Not the rivet stage but the glassing and sanding, just before painting. Sure would be easier before it is attached.
Don't even worry about hyjacking this thread. The more input the better, and I am learning as I go. Some clearification is also needed on my end regarding the set up with the 1/2 inch alum tube. I am concerned with it not aligning properly. I was planning on using a robart tail wheel retract on the corsair, putting it in the scale position, therefore rejigging the linkage hook up. I dont plan on attaching the rear fuselage until everything is done as it is much easier to get at.
I glued the starboard spar into the foam wing tonight, and sheeting will be next. I intend to sheet the whole wing, which is a change from the instructions.

Thanks for posting guys, and the heads up for some possible problems ahead

Craig

Status: offline 		Hi Les and Craig,
The fix I stated can be done after the stab is glued and aligned up if you prefer. I believe there is a 1/16 0r 1/8th ply former between the tailwheel bulkhead and the end of the fuse. The tailwheel retracts in the middle of it. This is where the aluminum tube glues to. If the stab is attached already I cut a 1/2 in slot on the bottom of both stabs and a slot in the bottom of the fuse, slide the tube through, apply epoxy, and imbed the tube into the stab. The middle part of the tube should be in contact with that middle bulkhead. I then glass that part to the bulkhead. If that bulkhead is not there simply run some lite ply or balsa from side to side in the fuse and sandwhich the aluminum spar between them. When all is dry, I cap the tube in the stab with 1/2 in balsa sheet , reglass the slot in the fuse,and finish as normal. You will be able to stand on this stab when it's finished. LOL. I hope this clears it up for you.
Thanks,
Fred

Status: offline 		Fred, thanks for the explanation regarding the 1/2 in tubing. I will think about this for a while to see what method will work best for me, not to sure at this point. I was also thinking about maybe using some 1/8 ply, and make the support spar that would go through both stabs and the fuselage close to the front. Just kicking around a few options.

Craig

Status: offline 		Hi Craig,
Whatever you decide will work and give the stab considerable strength. The main thing is to support the front of the stab . I was always suspect of butt gluing the stab to the fuse. Good luck with your build , I'll be following it. Your doing a great job and you will have an awesome looking and flying Warbird. Check out my Dave Boddington Hurricane build on RCU Warbirds Forum if you get a chance.
Thanks,
Fred
