Default Sig Four Star 40 or 60?

Hi Guys,

I'm considering a Sig Four-Star 40 or 60 for my first kit after flying a few ARFs. From the Sig website it looks like the main differences other than size are that the 60 uses two aileron servos and is "laser cut" while the 40 has one aileron servo and is die cut.

I'd appriciate any feedback for or against either of these kits as a "first build."

Thanks,

Carl

If you have to buy an engine anyway, and the price difference doesn't concern you, go with the 60. It's larger, and is one of the best flying planes I've ever owned. And I've owned a lot of them. Super easy to build. Strap a .91 four stroke on it and you have a dynamite combo. The Thunder Tiger .91 four stroke is perfect, and inexpensie.

Go for the 60. I have one and love it. Mine has a GMS .76 engine on it and it is a rocket with unlimited verticle.

Another vote for the 60 size. Bigger is better.

YA KNOW.........I have just looked at this plane yesterday and it's only $80. So i'm probably goin to get it for my next plane. I was considering a Extra, but everyone said that that would be too much for me. So, my people at the Hobby Stop said to look at the Four Star 40. See, I'm probably goin to get the 40.......and put soem over kill. I WANNA HOVER. You might be saying, why does he want to hover when he's only on his second plane? WELL, IT LOOKS SOOOO FUN. So what would lemme hover and have unlimited hover for an engine if I get the .40 size. Thanks Alot.

Thanks for the replies!

Other than "bigger is better" ...

Does the "laser cut" vs. "die cut" make a big difference between the four star 60 and four star 40?

Thanks!

Hello Cfossa:

The 40 and 60 size are very similar. However the wings are built differently. The 40 uses standard "D" tube construction. The 60 uses something similar but uses cross braced ribs. Lazer cutting gives you a better finished edges. More accurate parts. But die cutting can be just as good. The important thing is that the dies must be sharp and properly adjusted on the machine. Wood quality also has an important effect on die cutting. So there is more chance in having rough ill fitting parts using die cutting.

Having said this Sig does a very good job in Die cutting in my experience. I have built a number of thier kits and will do more in the future. I am a Sig fan as there planes fly very well indeed. I would say the quality of thier kits is very good. If you get some bad die cutting just get in touch with Sig. Thier customer support is great, and any problem will be taken care of quuickly. So fear not on either kit. I have a 4*60 under the bench to be built. I have looked at the kit contents an am pleased with them. I would go with the 60 of the 2 because as many before said "bigger flies better". I fyou have an engine laying around buy the kit that fits it and go for it. otherwise pick a kit and have at it. I wish you well.

Thanks Guys!

Good to know that they are both laser cut. I'll have to take a look at both at my LHS!

The 4*60 is a great kit to build. Builds straight, fast and easy. I built a 60 size kit about 8 months ago. I modified the plane some and put a YS. 91FZ up front. The plane now has dual elevator servos, pull-pull system, counter balance rudder, 1" extra on rudder and elevator, better tail wheel, front hatch compartment plus other small modifications. Using a Futaba 9C computer radio. You will love the way this plane flys. My plane can hover and knife edge very very good. Using a APC 15x6 prop. With flaps deployed, the plane will creep over the runway slow and level. I had to program a little up elevator when the flaps are down because the plane will try to dive downward when flaps are deployed. How slow the plane can fly will amaze you and your friends with the flaps down. Many stated that the plane doesn't need a motor like that, but I can't see flying any other way. The plane handles extra power wonderfully. Take off and go veritcal until you get dizzy or think "OK, that is high enough". Just make sure you secure the wing halves together nicely.

The 4 star 40 has turbulator spars instead of the D-tube leading edge and it goes together fast.
I have one in the box that I'm going to build after I get my Sealane finished(the Sealane should be done in a few days). I'm going to build it to look like a crop duster I think. Have built 2 4 star 40s and a 120 size and they are great flyers everyone of them.

Just a thought but a good alternative to the 4* 60 is also the Venture 60 from BTE Models. Bruce Tharpe is the one that designed the 4*. He left SIG and started his company and pretty much redesigned the 4* with a couple improvements. You might consider taking a look at it. The kit is $150 with all the included SIG and Dubro hardware and Fiberglass wheel pants.

Default RE: Sig Four Star 40 or 60?

Ok, can't resist putting my two cents in.........I'm flying a 4*60 and love it but, my 61fx is not really enough motor. Definately go with a 75 or 90 size two stroke or YS91, Saito100, Or one of the 120 size four strokes if you want good vertical. My 61fx is ok for flying it like a trainer but vertical and large loops are lacking. Mine's modified also........Larger cap style rudder and clipped last bay off each wing half. That mod makes for a lot nicer roll rate. Even with the clipped wing, it slows to a crawl to land. I'd recommend the 60 size plane for sure. Lot more visible and presents itself much better doing aerobatics.. Just have fun whichever you choose.

Gare try using a GMS .76. I have one on one of my 4*60's and it is great. Look at www.gmsengines.com and you can get one for 85.00 shipped to your door. This engine was very easy to break in and tune. It ran great right out of the box and once broken in all I had to do is fine tune the low speed needle a little. I was flying it with a master airscrew 13x8 scimitar prop and it would just keep going vertical. My other 4*60 has a magnum 91 4 stroke on it and I haven't gotten to run it yet. (Maybe tomarrow) I am really excited about this combo and think that the vertical will be outstanding. I love my 4*'s and will always have one in my hanger.

I finished my second 4*40 not long ago...the first one flew through a tree(or at least tried to!). I put a servo in each wing for the airlerons... was an easy mod to do. Laser-cut, went together easily. Has an OS46FX on the front and will easily fly around the sky at half-throttle, lands as slow or slower than my trainer.

Default I am building my 3rd 4*60. Interesting bashing possibilities

I am building my 3rd 4*60. 6o is the better plane because of the size, it flys great and you can see it soo well. Great construction. But here's the little twist I'm trying:

I am bashing it into an Eindecker!!!! removing the turtle deck, rounding over the vert/rudder, triangle ends on wing and horizontal. my friend is even suggesting I put the wing on top. I will add scale pilot, machine gun, etc. I am looking for any tips. Covering with Nelson and painting with Latex!!!

why do it? I still need experience flying and the plane is just right for me. But I am also a scale guy on the inside. Great combo.

I have had a couple of 4*60's and have flown numerous 4*40's. These planes, in my opinion, are 2 of the great basic designs in RC. They can go from mild to wild, as they say, depending on power and control set-up.

As someone mentioned, if you are not a rank beginner, the 60 size will be underpowered with a .61. My 2 have had an OS .91FX and, presently, a Magnum .91XLS. If you are a pretty good flier, a full wing, .61 powered 60 will bore you to death in a few flights. The 4*40 with a TT .42GP flies about the same as a .61 powered 4*60.

With a good, ball bearing .46 in the 40 or a .91 in the 60 you have the power you need for some fun.

Both need 1 rib removed from each side unless you want it to fly trainer-like. Makes the rolls much better and snaps crisper. Does not seem to affect landings. Take 2 ribs off and you can start thinking fun fly. Does land a little faster, but nothing drastic.

Both need an inch added to the rudder if you want better snaps, spins & knife edge.

Actually, you could make a career in RC out of flying modified 4*'s. You can bash them into anything and it doesn't seem to affect how it flies. You can teach someone how to fly on one. Chop the tips and put on larger controls and you've got a fun fly.

The 4*60 is the way to go. I built one from a kit, put an OS 91 FS on it. Just loved it !! Then one day "dumb thumbs" and low-inverted caused me to buy another one. There is a guy at our field who flys a 4*40, and he says he's thinking about a 4*60 after watching mine fly. It's a great kit to build. And a SUPER flyer. I can even get mine going backwards in a hellova headwind !! It's that stable. Well, there's my two cents worth. Enjoy-John

OK, I've reading a LOT about the 4*60. My issue is with the engine. I have a 4*60 in the box and three engines, K&B 65, O.S. 91 4cy and a brand new O.S. 1.20. Which one is best for a pilot that loves to fly but not brake the sound barrier?

I love my 4*60. Have had a 4*40 so can tell you that the 4*60 is smoother flying. You won't regret stepping up to the 4*60. I fly mine with a Saito 91 and it hovers reasonably well. But if I were buying today, I'd opt for the Saito 100. Have fun whichever way you go.

Hey Bolt-If you already have an OS 91 4 stroke, that's the one I'd use. The 120 is too much power, unless you are at 3 or 4000 ft. elevation. Then the 120 would be better. I also fly mine with 42 in. Sea Commander fiberglass floats. The 91 4 stroke does just fine, except when I flew off a lake at about 4200 ft. elevation. It did fly, but took for ever to get off the water. So, any way, I'd use the 91. It should do just fine for ya. And you'll just love the plane. It's not supposed to be fast, any way. It's an areobatic trainer. Have a ball-I know you will.

I just maidened my 4*40 this morning. I have a MAgnum .61 RFS (4 stroke) up front and verticle was literally unlimited. It flew straight and true off the board - it was quite literally one of the finest planes I've ever flown in my 20 or so years doing this.

I was very very pleased with it and really I think the choice is simple - which ever one you want - you can't go wrong. I have a friend who has 3 of them - a 40, 60 and a 40 kit on the board. I'm really amazed at it - I never would have bought one myself but I won it at a raffle and I could not be more please.

Enjoy!

It's a fantastic plane.

A lot of people talk about taking a rib off of each wing. Thats one rib off of the outside of each of the wings right? Not the inside? Thanks.

Yes T-Maxx, leave off the outermost rib if you are planning to clip the wing. I've built it both ways and actually prefer the full wing. Every once in a while I like to hang it in the breeze nice and slow. Enjoy the plane!
