So great to see everyone at Top Gun wearing the Waco shirts! We had some crosswind to contend with but it was very nice weather this year and a great group of pilots with incredible planes...

I was about a month shy of completing the Waco in time this year but hoping to finish soon and get some good flights in this summer. Having a lot of fun with the detailing and thanks to everyone who has generously contributed with tips to learn from.

David just sent a nice photo of the Stearman I flew this year in place of the Waco. We lucked out with some beautiful sky to fly in.

I have 2 x XL Waco shirts that I will post free of charge to any brother who missed out or wants some extra ones. I ordered the wrong size and they may as well go to a member that can get some use out of them. If you want them PM me with your name and postal address and I will send them off.

REGARDS TMAC48

The shirts are on there way back to the USA. I look like #hit in yellow anyway!
tmac48.

tmac48 I hate that happened I had you down for XL what size did you need? If I messed up I will make it right some how.

Dan, not your fault,I received what I ordered, I messed up plain and simple! Time to move on and await the next issue, in fact I think I might get myself some WACO shirts done here locally, I will post photo of shirts when done.
Regards tmac48. PS moving house at the moment and a little pissed off at the fact that we leave our present home in pristine condition just to spend $$$ to have the new premises cleaned good enough for us to move into! makes you loose faith in your fellow human being,
Need to install receiver in the WACO and go fly!!!!!!

At Long last I have finished my 1/3 scale Barth Waco YMF-5. Alas! it seems to be nose heavy with the Moki 215 installed. Not justa little, but over two pounds of tail weight seems to be required to attain the CG on the Barth plans.
Has anybody else had this problem? I have measured this about 4 different ways and they all seem to come out within a few ounces of each other.. I just can't see adding that much weight to the bird, it weighs 46 lbs already.
HELP!!

John,
Go back to page 710 post 1734 and Bill explains how to get the correct CG. Hope it helps,

John. I have a DA 150 in mine and although it may not weigh as much as your MOKI I have a very heavy 2 inch solid alloy engine mount and a alloy front behind the cowl, all up I am sure I would have as much weight up front as you have. I also have all my battery's behind engine mount. With this set up my CG came out at 8 1/2 inch's behind leading edge of top wing. Have not flown mine yet but pretty confident that it will be close enough to be controllable By the way I would be happy if mine only weighed 46 lb :rolleyes:

Could someone please post a picture of how they arranged the servos on the 1/6 th scale version. I'm having a bit of an issue coming up with a good arrangement. Thanks.

Thanks , got it worked out now.

Hey guys, I have a Pica Waco YMF 3 kit for sale, 60" wingspan. I had it squirrelled away for a rainy day but I'll be dead before I find the time to build and fly it.

Anyone interested? I considered just putting it on ebay but not sure if that's the ideal way to find the very best home for it.

Flyrc67, can you post some pics? That may help someone in the future.

Here is my layout with the 1/5 Pica. Was a bit of work to build the servo bays in the wing to replace the stock bellcrank setup, but would have been a lot simpler during initial construction. Same with hogging out the rod slots in the ribs and feeding the extensions to the center. Well worth it, though.

Hey guys,
Just wondering any one still waiting on there tee shirts to arrive? hope not but let me know if you haven't got them yet.

As they say "the third time is a charm", that is how many times I had to revise the pushrod dog leg bend to get the right amount of throw on the elevator. I ended up lengthening the quick connect side by about 3/8" from the plan drawing to get it to work. Also ended up using the same dog leg bend on the rudder side, which is totally different than the plans. Elevator throw result is 1-3/8" twice what the plan recommends and almost 2" throw on the rudder. Attached is a picture of the final set up. Hope it helps.

For some reason the picture won't upload.....

Now that's a great looking cake one of a kind.
Happy birthday shaked.

Hi Shaked,
that is one fine looking cake,
HAPPY BIRTHDAY TO YOU

thank you

Hello WACO Brotherhood. Wow, what a long thread, 731 pages! I hope you won't be offended if I ask a question without actually reading all 731 pages.
My question concerns the Great Planes WACO YMF 1.20 ARF and engine selection.
I have an OS 1.20 Surpass II that I could use but I would like to have a little more power than scale.
My first choice would be to use this engine, http://www.horizonhobby.com/airplane...engine-evoe735
Or I could go with this one, http://www.horizonhobby.com/airplane...3A-bi-saie150b
Or this one, though I'm not sure it would be any better than the OS 1.20. http://www.horizonhobby.com/airplane...--bh-saie120r3

Two stroke engines and gasoline engines are out of the question. Personal choice.

Opinions please.

Thanks,
Keith

The EVO 735 weighs in at 3.1 lbs and will likely make you nose heavy. I flew mine with an OS 1.60 Gemini Twin which weighed 11.5 ounces less and swung an equivalent sized prop and had a higher RPM range. If I recall correctly, I did not have to add any weight to balance properly and I think it flew scale-like at 1/2 throttle. No cutting of the cowl required except for the a notch in the back edge of the cowl for the exhaust pipes to sneak out. The Saito might not be a bad choice. Its close weight-wise and a lot cheaper but you lose the sweet sound of a twin and I don't think it will swing as large a prop as the OS twin.

I've got the OS 1.60 in a GP Super Stearman and it is a good choice for the Stearman. What I didn't like was waiting 15 weeks for a muffler from Keleo Creations for the 1.60. I would love to use the radial but I certainly don't want to add weight to balance it. Of course the Saito 1.50 is out of stock. What about the 1.20R3?

Thanks,
Keith

For the GP WACO you don't need a Keleo muffler. Two lengths of slip-fit K&S brass tubing. Heat them cherry red and let them cool, then bend to shape. A simple strap made of brass and screwed to the firewall will capture the rearward ends and keep the pipes in place. If you want a pressure tap, that is easy to add as well. Total of about $3.00 in materials.
