Four Star 40 revisited
 

My second plane and first build was a Four star 40. It turned out well and I enjoyed flying it, but a rookie
mistake cut it's lifespan short. A while back I decided I wanted another one.
I had this build posted on another sight that recently got closed down.

The kit box is a little smaller than I remmembered and there isn't much in it, but the contents are
typical Sig quality. My original was die cut, this one is all laser cut.:)

RE: Four Star 40 revisited
 

I started with the wing. The trailing edge and bottom spars are pinned down. Then the ribs are squared, the tacked
in place with thin Ca. I backed the joints with med. Ca.

RE: Four Star 40 revisited
 

The root rib is glued in place at the proper angle using the provided gauge. The trailing edges pieces are then put in place.

Nice build, Skyraider.

I once scored a Four-Star 40 at a local flea market for $25... the only problem was that it only had one wing half... Apparently the original owner built the other one and then gave up interest...

But I'm not discouraged. I'm going to modify the wing saddle area slightly and make my own wing from a Selig 8036 airfoil. I did that once before and noticed a difference. But another one that I had, which was stock, also flew very well.

Did yours have that 'whistle' that only seemed to come from a Four-Star 40?? I really loved that plane and can't wait to dig into it again.

Mmm, never noticed a whistle from the FourStar, but I do get a little noise from the tail wires on my SSE.
Why not trace out the ribs and build the wing? Sig does offer wing kits for thier planes.

RE: Four Star 40 revisited
 

The shear webs go in next, Sig cuts these for us! The top spruce spar then goes on forming a strong I-beam
structure.
Note the holes in the ribs, those were meant for wires for running lights that I decided against.

Skyraider71: The 4* 40 is a great model to bash into a WWII fighter model. That is what I am going to do with my build. The fuse was started some time ago, and I got diverted from the workbench. My favorite plane is the Naval SkyRaider you have on your address page. I have the 40 size model from Global Hobbies stored now. Keep us in the loop on your second build of this 4*40.

A warbird look alike would be pretty cool indeed. I've heard suggestions of a crop duster conversion, something
like a Pawnee or Thrush. I could see that also.:)
BTW I'm a big fan of the Douglass "Able Dog" I wish there were more models of it.
When I saw the movie Flight of the Intruder I thoght the "sandies" were the coolest airplane I had ever seen.

RE: Four Star 40 revisited
 

The square stick leading edge is fitted into notches in the ribs. Accelerator is a big help here.

RE: Four Star 40 revisited
 

I began sheeting the wing with 1/16 balsa using Ca to attatch it to the ribs, and wood glue at the
joints. With the top sheeting complete I removed the panel from the board, to my delight it's as straight
as an arrow.:)

RE: Four Star 40 revisited
 

The bottom sheeting is now completed.

RE: Four Star 40 revisited
 

The left panel was done just like the first.

RE: Four Star 40 revisited
 

The leading and trailing edges of both panels were then shaped with the sanding block.

RE: Four Star 40 revisited
 

I've always liked this simple little plane. I had an ARF version a few years back until I mid-aired with an Ultra Sport 40. We were racing around down low and I yawed into him through the turn [:o]. Took us both out [:@].

RE: Four Star 40 revisited
 

Nice to see your 4* post i am starting to see some of us here from R\C HO have fun

AKA: newflytexas

RE: Four Star 40 revisited
 

This is a strange post.

I recovered the fuselage last year with the intent to eventually recover the wing. It was originally tan/cream (wing) and green (fuselage). I I covered the fuse with metalic red and white. The wing would get a similar treament when the time came. I finally finished the wing a couple of weeks ago along with the addition of dual aileron servos. The first couple of flights went well but the next day, it crashed and broke in half at the wing saddle. We have aguy in our group that does amazing things when repairing planes. I turned the fuse over to him and onve returned repaired the covering.

I've attached pictures of what it look like now.

Thats a good lookin' Bird! I crashed mine so bad there was no saving it lol!

RE: Four Star 40 revisited
 

Mr. Breeze.. Skyraider71.. What happened to the build sir?

Here's my ol 4* clipped 'n piped, still flying good and KY proud! Hope to see ya in June sir.

Peace,
J

nice man i own one four star to but the bigger brother 60 but i have fly a 40 and its a really fun bird to fly ;)
here is a picure of mine

RE: Four Star 40 revisited
 

Sorry guys. I left this sight for awhile. This plane got completed and has been enjoyed. I still have the pics, so maybe I'll post
them.

RE: Four Star 40 revisited
 

The servo cut-outs are made using the supplied template.

RE: Four Star 40 revisited
 

The wing panels were prepped for joining, the ply dihedral brace was sanded to a perfect fit.

RE: Four Star 40 revisited
 

The panels are now joined with epoxy in the usual way. The wires shown were part of a led lighting
system that I decided to remove. Turns out that glow models are not a good choice for night flying.

RE: Four Star 40 revisited
 

Here the wing lies next to the remains of my original FourStar. One thing I noticed was how far my building
skills had come since those days of fumbling through my first aircraft build.
