Hi guys,
This is my first attempt at chronicling a build so let me know if I missed anything important.

First off if anyone is wondering why this ARF costs twice as much as a Phoenix or SeaGull ARF?? Once you open the box and check it out you will not be. The packaging is clean and all the parts are of amazing quality. Sig included a very nice tail wheel set and pull-pull gear for the rudder. The hardware is of better than average quality. I expect to use it all. The manual is very detailed with pictures where needed. The best part is half the work is already done for you. Both wings are complete, the covering is cut away from the tail surfaces and servo slots.

OMG!! Check out the level of prefab here...



looks like they have a plywood block sandwiched in the fiberglass with blind nuts installed.

Cowl even has holes drilled for the mounting screws.

Contents of box



horizontal and vertical. notice the removed covering

My only issue after checking it over is that the bottom and the top of the wings have nearly identical covering. It may be difficult to tell if it is upside down or not.

Speaking of sig and prefab. When I assembled a Rascal 110 last year, it took me 10 minutes to put together the entire main gear assemble including wheels, and wheel pants. This included the time to find all the parts and remove them from the plastic bags and read the instructions. I've spent days cutting and sanding and gluing wheel pants with other "arf" kits so the Sig gear was a sweet surprise. Looks like the sundancer has a very similar gear setup to the Rascal. Sig does seem a bit more expensive when you are looking at the outside of the box, but once you dig in and start putting things together, you realize how nice their stuff is and it's worth the extra money. Every thing I've had from Sig flies wonderfully. I've never met an airplane I didn't like, and there is a lot of other good stuff out there, but you just can't go wrong with Sig.

Has anyone flown this plane yet?. I'm thinking about getting this plane. I have an OS70 without a home.

Looks like I may be the first to maiden mine on RCU. Should have it done around the end of the month.

good, let us know.

Well I finished the plane on Saturday & was hoping to maiden it on Sunday but the wind was a little to strong for the first flight so maybe next weekend. Assembly was fast & easy. The instructional manuel was very good with lots of pictures. It balanced perfectly using a SO 70 Surpass. My only complaints are the covering wants to come off at various places & the paint on the cowl & landing gear chips off easily I'm going to contact Sig about this today. I'm a little surprised that no one has flown this plane or if they have nothing has been posted on this site.

My dad just picked one up but has yet to start it. We did look over the contents and were also very impressed with the quality. My dad bought this to replace his Kyosho super Stearman which he finally had to retire. He should be starting it shortly and will be powering it with the O.S. .52 four stroke that he had in his Stearman. Should be a nice match for the Sundancer as the span, wing area, and weight are virtually indentical his Stearman and the .52 FS flew the Stearman great. I'll post picks as he gets started.

dawg

Can't wait to here the flight report. Sig makes great ARFs, I have several and all have been top notch.

Has anyone flown this plane yet? Futaba, YS 63 13x4 prop

Someone at our club has one finished and it seems to be a very sweet plane. I had thought I would buy one too, even though I usually don't get planes that other people in the club have. His is orange and yellow, I was thinking of the purple one for myself. but I actually have a Hobbieco ultimate byplane 40 size only problem is its out of production for many years now and the instructions are missing. Been planning to sell it , now thinking I might put it togather and fly it.

I hope to fly this weekend. Busy working to support the addiction. I will follow with a flight report when I can.
I like bipes. I, unfortunately, killed my Koysho 40 Stearman last weekend. It was a great flyer! Not too aerobatic though.

A couple of pictures from the building experience.. I found this kit to go together quite easily and it balanced perfectly with the recommended engine.

Hi all, was wondering, the specs say 8.79 OZ fuel tank. Ghost-RCU how much flight time do you get with the OS .70? Isn't that a little on the small side?

I haven't timed my flights but I'm sure I can get at least 10 min to 12 min out of it. I'll fly it this week & let you know. The OS 70 Surpass pulls it around well & its easy on fuel, more than enough power for this plane.

I put an OS 65la in mine, flies great! You will have a lot of fun with it. I had trouble taxi-ing mine, but I fly off grass, had to adjust the tail wheel, now no troubles. Also you might want to put a little thread locker on the turnbuckels on the pull-pull system, had mine come undone at the servo. All said and done, real nice plane.

I just finished my Sundancer 50 - last week tried to fly, but kept nosing over. I double checked the CG and the balance point was right on 3 1/4 inches. Also trying to fly off grass - wet grass then, any ideas - balance point per manual working for everyone? Grass field the problem, maybe even pilot error

k7pa, I ended up taking the wheel pants off, putting bigger wheels on, and bending the tail-wheel arm up towards the fuselage. Like yours, mine balanced properly. Since making the changes, I have had no problems taxi-ing. The plane still looks good without the wheel pants. Before making the changes I tried about everything I could think of, but it kept nosing over, even with maximun deflection on the elevator.

Thanks for the quick reply. I was thinking along those lines. I'll try the tail wheel first - hate to get rid of the wheel pants, but like you may have to. Again thanks.

I fly off grass & still have the wheel pants on. When I start to taxi I goose the throttle a little. Once rolling I keep in up elevator until I get it rolling for takeoff. I haven't had any nose overs since using this method. Give it a try if you haven't already. I also had to bend the tail wheel assembly towards the fuse.

Well guys I found this at the LHS. I thought it was the yellow version but when I got it home I found out I had the purple one.

I've liked Sig airplanes and had good experiences with the Rascal. The Rascal was covered in Ultracote. This Sundancer is covered in AeroKote. I'm not impressed with AeroKote seems like Chinese covering to me. Low temp and doesn't stick or shrink as well as Monokote or Ultracote.

I did not like the same covering pattern on the bottom of the wing as the top. Nor did I like seeing the white plastic servo covers against the purple and blue colors. So I added 3" wide stripes out of Ultracote. I liked the 1/8" pin stripping on the fuse and added 1/16th " on the wings. What do you think?

The plastic servo covers will fit in the middle of the stripe. I'm also going to epoxy the bottom of the plastic servo covers with 1/64" ply. I had a problem with them deteriorating on the Rascal.

I don't have a .70 4 stroke and I hate the idea of a large 2 stroke muffler hanging out the side. I looked at the weight of the Magnum 91 verses the 70 and they are really close so it will be getting the 91 and a 13 ounce fuel tank.

I don't like the covering on mine also, but that's my only complaint
