Thanks for the info.

I'll let "The Next Guy" fix this problem to his liking.

If you get my drift...

Hi Dick thanks for all the information on assembly and flying the 1/6 Pico WACO. I have purchased one as well but have not yet started to assemble it yet. You said that the Saito 80 is all the engine this plane needs. Do you thing that a smaller engine might be a better fit.
I was intending on installing a OS FS 91S II four stroke in mine. I also have a OS FS 70S II four stroke that I might try after reading that you flew yours at half throttle and still were going faster than scale speed. Any thoughts?

The OS 70 will fly it OK, but you'll probably need some nose weight to balance.

You may not have to cut a hole in the cowl either for the cylinder head.

The advertised engine-only weight for the OS .70 II is actually a few ounces heavier than the Saito .82. It's tough to beat the Saitos power to weight ratio.

It sure would be nice to eliminate cutting that beautiful cowl.

yep, but the saying goes. Always can use the front end weight in a bi-plane. OS comes with the lead built right into the engine!

If any of you would like to order the WACO Brotherhood T-Shirts, have a look on the Vintage and Antique site on the WACO YMF thread. Damifino is taking orders. These are gorgeous shirts.

Dick,

If the engine was installed rotated a few degrees to get the rocker covers on the Saito lined up with the cowl bumps, could the cutout(s) in the cowl be made smaller? I realize you may have been stuck following the directions to mount it at 90° or the blind nuts for the mount may have been pre-installed, but it would seem to make sense to rotate it a bit and line up with the cowl bumps and an engine cylinder (# 6 cylinder would hide the cuts better than #7 and still be nearly horizontal). The first 2 pictures are of Continentals in a UBFs (NC 2019K & NC 155Y), the last is a Jacobs R755B Series in a YMF (N50YM), the Cartier YMF from the Airliners site. The # 1 Cylinder is center top on all three.

Picture of the shirt design is found on page 80, post 1999. It is totally cool.

Possibly, but I have my doubts. It's not just the rocker boxes that hit the cowl.

Thanks, I wasn't sure from the picture in post # 7, it looked like the head was clear but not the rocker covers.

No video.

The plane is in the hands of its new owner anyway.

Dick,

I read the entire report in RCR this past week. I still think that it's a good bargain for the guy who wants a WACO without having to go through all the contortions required to build one.

1/4 the way back from the leading edge of the top wing to the trailing edge of the bottom wing with the airplane in flying attitude for the first flights. Lots of elevator and rudder movement. Mix 50% rudder to aileron. Fly it first, then adjust to taste.

God! I love that A/C. Built 2 YMF-5. both Dave Platt kits. The things were astounding flyers! Aerobatics in slow motion!
I used one of the first YS 120s and they had more than enough power.
Landings are something you'll have to learn. They want to run along on the mains, till the airspeed is bled off. 3 points are tricky.
My Ultimate IS fun, but as graceful as the YMF!
Hunt up some pilot reports on the real flight. It's an old timer, but still a lovely flyer....

Hi all,
can someone please inform cowl diameter of 1/6 waco ?
Just wondering if I could fit a Saito radial 3 cyl 90 in it.
Thank you.

Thano,

The 170 radial is too big for the 1/6th Pica/COX/Platt Waco but will fit the 1/5th. Go to Vintage and Antique forum, WACO YMF and look up the 170 Radial in the index in Post 1, click the blue numbers and you are taken to that post.

Thanks for the reply but I was asking about the 90 radial not the 170.

Thanos,

Whoops, I forgot about the 90 radial. The Platt and Pica plans show 6-3/4" (171.5mm) at the rear edge of the cowl, 6-5/8" (168mm at midpoint, about where the cylinder(s) will be) and it is 3-7/8" (98.5mm) long. Sorry for the confusion and hope this helps.

I would give the 90 radial a second thought. I do not think it has the power required to pull the COX/Pica ARF. Check the specs on it first. The sound though would be great.

John thank you for your reply.
I have to check the engines dimensions again but I think that the 90 radial will fit.
It will be a tight fit for sure but the looks and sound will be great.
Now as far as the engines performance. I have seen a 90 radial pulling a Hangar 9 sopwith camel.
Not too much power but scale flying.
Having in mind that the h9 sopwith is about the same weight and wing span like 1/6 waco, I think it will worth to try it.
On the other hand I'm not going to buy the Cox / Pica ARF but will build the pica 1/6 kit and try to keep it as light as possible.
This doesn't mean that it will be lighter than the ARF but I will give it a try.
Any way I think that it would be better start building and at the end I will check the weight without the engine and then decide if I would go for the radial.
I expect model to be a little tail heavy so maybe the r3 additional weight will balance it better.
Hope to find someone who has used this engine on waco 1/6 before in order to have an opinion.
Or else I'll be the first to try it.
Thank you,
Thanos.

I doubt that the Pica kit will build into a tail heavy model. Mine balanced perfectly, with an OS 91 Surpass.

Well Tom ,
that means I'll have to move things back. Receiver battery etc.
Do you remember the total weight of your Waco ? And was it a kit or arf ?
Thanks

Mine was one of the last kits. It was a joy to build.

It flew well on the 91 single cylinder. Your radial may be a little less powerful.

I'd be concerned about the added weight, but it may be doable. I know that the sound will be awesome !!!
