Hi, test flew waco with 90 Saito twin this morning in dead calm conditions.Take off is a bit longer[on grass field] but plenty of power,half throttle is about right and the sound of a twin makes it very realistic.Also chaged wheels to three and a half inches and put a scale tail wheel setup.Used flexipipe for exhausts welded to header pipes, also turned up a custom nut to fit spinner.Just waiting for a onboard glow to turn up and get the cowl back on.Also found tuning engine with tacho the most reliable.

I started the breakin on the Saito 100T this morning but attempted no flying as it was quite windy. The engine ran fine but I had to stop before I could peak the RPM because the on board glow battery ran dead. It's 1600 mah and was good for about 40 minutes of continuous use. I'll run it again tomorrow and lean the carbs so I don't need continuous glow power. The twin cylinder engines sure sound nice, don't they? Did you still use the wheels pants with the larger wheels? I was thinking of doing the same because our grass can be thick at times.

Here my finished product. Maiden flight tomorrow if the engine cooperates? The flying wires are not difficult and take me less time to attach/remove than the "N" struts. Once rigged all that is necessary is to remove the 4 attaching screws from the lower wing.

Looks great silver.kiwi. The flying wires add a lot to the scale looks. Does it come with a dummy engine? That would be the finishing touch. Nice work. Can't wait to hear how the maiden flight goes.

Maiden flight complete........zero faults. Here's the offical poster pictures of the event. I was alone at the field so I couldn't get any airborne shots. The Saito FA-100T pulls the plane with good authority and takeoffs are short even on the grass. As for the plane itself, I could not be more pleased. Two clicks of right aileron and two clicks of down elevator and she tracks straight as an arrow. Drop the flaps and it lands like a feather. Want to do unscale aerobatics? That's O.K. too. That's a great testament to a straight airframe thanks to SIG's engineering and jig built laser cut parts. First comments about the lower wing aside, this is a great model and with great quality throughout. The instruction manual is the best I have seen with an ARF. I don't know who the author and proof reader are but they are to be commended. I suspect Scott Christensen. Although a dummy radial does not come with the kit I purchased one but probably will not install it as I hate covering up the FA-100T.
Thanks Silver.Kiwi! You not only have a beautiful model, but your flying field is also something to be jealous of! Has anyone placed any video clips of the Waco online yet? I can't find any anywhere....

Silver Kiwi, Congratulations on your Waco maiden! If you're anything like me, my own Waco very quickly became my favorite! It's as much fun in the pits as it is in the air. And for such an interesting model, I've found it to be virtually viceless in its flight envelope. I'm pleased as punch that you have enjoyed the assembly, as well as the flight of your new model - after all, THAT was the whole idea. I know that you're rightfully enamoured with your Saito 1.00 twin, but I still have to say that a nicely done dummy 9-cylinder radial in the front really looks nice, at least in my humble opinion.
Again, congrats and I sincerely hope that you continue to enjoy your great looking model! Kind Regards, Scott Christensen SIG Mfg. Co., Inc.

Silver Kiwi, how do you adjust needle valves with the cowl on, i cant see any extentions from the photos.
The answer to that is, I don't. I've found in the past that once the engine is running correctly I try not to mess with it. I'm hoping this one will be the same as I HATE cutting holes in the cowl. Also, this cowl fits great (no complicated engine or exhaust to fit around) and is easily taken off and put back on if needed. The only hole is in the left side for the fueling service valve as shown in the instruction manual. How did you accomplish the job with your twin cylinder .90?

Yours certainly does look nice and I may rethink the idea after I am able to get a new union nut for the correct spinner. By the way, what did you use for the cowl scoops on the lower cheeks?

I test flew mine without the cowl[still waiting on onboard glow]and only have three holes in cowl.One for the fueller,one for needle valve [asp 90], and one in the bottom to clear rocker cover[asp90\]If i have to fit extentiones to needle valves i will try and dummy them up like fuel cap and breather, how ever you cant see them when flying.I prefer practability on my planes.

I have to agree with Scott, the dummy radial really completes the model. I rarely fiddle with the needle valves on my Saitos either but I do usually run an extension out through the cowl.
Congrats on your maiden flight, kiwi! Sounds like it flies as good as it looks. I'm hoping to be able to order mine after the Perry (GA) swap meet.
