Hi Ron,
Sorry for the delay, I haven't been on the computer in a few days.

The threaded end goes in the gear leg, a nut on each side of the gear leg to secure it to the leg. The head of the bolt needs to be cut off. I cut mine off so the axle just contacts the other side of the wheel pant. I glued plywood disc to the inside of the pant with a hole in the disc the size of the axle. This will secure the outside of the pant to the axle and give it enough support to keep it from moving. The bolts going thru the gear leg into the wheel pant blind nuts keep the pant from rotating. I hope this makes sense?
Use plenty of epoxy to secure the plywood disc inside the pants, both for the blind nuts and the axle end.

For the most part my back is better, the nerve pain is gone. Every now and then I get a lot of sore muscle pain in my lower back. I am hoping this goes away with time. I have been spending as much free time as possible flying with my grandson. He is now 6yrs old and flying on his own. The little guy has yet to crash a plane. Kinda peeves me off a bit. He won't listen to me anymore while flying he just say's I know what I am doing.
Later!!
Anthony

You're one lucky grandpa Anthony! I hope to be at that point someday with my grandson! And it's good to hear the back pain is diminishing. Just don't over do it, I want to see another build thread!

Gentlemen, I finally pulled the trigger on a DA-150 for my Barth/Proctor Waco. I pulled the old brison 6.4 off, and it was set 0-0. I fly a 1/3 super cub 0-0 with a 120cc, and never noticed any tendency to pull to the left, except on floats, so I apply throttle smoothly.

I read many, many pages back most of you reccomended 2 degrees of right thrust. Bill implied it's not necessary. I'm about to build a new motorbox for the bigger motor, and wanted to see what you guys thought before I go 0-0.

I did all my flight training in taildraggers, so using rudder is natural to me.

Most of my planes are set 0-0 on the thrust angles as well but I did go with the 2deg of right and 1 deg down thrust recommended by AMR on my big WACO. The plane does track well thru loops and does not climb excessively with throttle. Even with the right thrust you need to be on your toes with the rudder on take-off and apply throttle gradually or she will take a sharp right turn with the torque of the engine.

I would say 0-0 would work fine for the WACO just a matter of trimming for it.

My 50% Smith Miniplane is set at 0 - 0 if that helps.

Anthony, It's been a while since you finished your Waco, are you still enjoying flying it. I had to stop on mine because I was flying my 1/3 scale pup in the fog and hit a tree, almost a total rebuild, anyway I'm back on my Waco build.
I'm going back through your build to familiarize myself where I left off, thanks for your advice, help and your build...........Ron

PS: I hope all is well with you and your family

Hi Ron,
The WACO is still in one piece. I did not get to fly it at all last year due to health reasons. I had 2 surgeries that pretty much ruined my flying. I do plan on flying it this year. The grandson and I made our first trip to the field yesterday and had a great time. He is 7 yrs old and he flew my Twist 60 and rung it out for 2 flights. Kind of scared me a bit, he was flying inverted about 50ft of altitude. The kid has no fear flying my planes.

Enjoy the build and yell if you need any help.
Anthony

Anthony, I hope the surgeries corrected the problem, what a bummer!
Hey! I wouldn't have any fear flying your airplanes two feet off the ground inverted either. Ha!Ha!
I have a couple grandsons but are not interested in flying, (GIRLS) what can I say, I have a couple of great granddaughters and a great grandson, not interested either.

Thank you for the kind offer, if I get stumped again I will yell,..............Sincerely, Ron Gooden

Anthony, I know there was a controversy about raising the front of the stab 1/4 to 3/8 of an inch, also it was stated that the CG was off that it needed to be relocated approx. 3 inches in front of the rear strut connection.
My question is, If the CG is moved forward does the horizontal stab need to be changed, by moving the CG forward makes the tail light.
By the way, the Waco is coming along great after studying your build.............Ron

Ron,
I did both. I raised the front of the stab a little, maybe 1/4" and moved the CG forward on the rebuild.

The plane is much more stable in pitch and is pretty much neutral on the elevator trim. I had quite a bit of down trim in the plane the first time around.

The one thing I can't stress enough is to keep power on during final, she will bleed speed in a hurry. Also keep the air pressure to a minimum in the tires. This will help reduce the tendency to bounce on landing.

Later!!
Anthony

Anthony, great advice on the power thing, I cut power all the way only after the wheels touch, the guys think I'm a great pilot, they don't realize they could grease them in if they kept a little power on, aircraft are unstable without air going over the surfaces, especially biplanes.
I'm a little afraid of lightening the tail surfaces like you did, so I will set mine at .375 inches positive on the stab.
I have that eleven pound Moki to give me the nose weight.
Low tire pressure definitely!
Thank you Anthony,
Enjoy your weekend!

Hi Guys,
I bought Real Flight 7.5 for my grandson and he wanted a WACO downloaded. I went to the Knife Edge site and downloaded Ken Spears (aka Big-Bird) WACO. The grandson liked it but wanted one that looked like my WACO. I asked the guys on the Forum there if they would create a color scheme for my WACO. Doug Schulte obliged my request and created a color scheme and AV file for the performance I requested as well. The plane looks and fly's like my WACO. If you have Real Flight and want to download the WACO search for Waconut Dark Blue with numbers. Also need to download the required EA file and then the Waconuts WACO YMF-5 AV file.
Later!!
Anthony

Put 2 more flights on the WACO today.
Finally getting comfortable with flying the plane again. I need to swap out the 34x10 prop for a 32x12 to get some more speed out of the plane. The roll rate and aerobatics are a bit sluggish with this prop.

Here are a few pics from flying today.

I bought a new Xoar 32x12 prop for the WACO.
The blade tips are not very scale so I rounded off the tip a bit and painted it up like a Sensenich wood prop. I used gold paint to simulate the brass L/E reinforcement and steel paint to simulate the fasteners. I had some Sensenich decals on hand that I got from Gary Siebert at Pink-It.net I applied the decals then sprayed 4 coats of clear gloss. I also used the clear gloss to balance the prop.

I will fly the WACO again this weekend and see how much it improves the performance.

Later!!
Anthony

Anthony, Great job on the prop, that should finish the look of the aircraft, is it the light or do you have black on one blade and blue on the other.
Experimenting with these large props gets expensive, I have had the best performance on my biplanes using Xoar props..........Ron

The tips are actually green.
The lighting was not the greatest when I took the pic. With these props costing over $60 a pop you don't want to have to buy too many for sure.

Sorry Anthony, I'm blind in one eye and can't see out of the other.
The price of these props will keep you from nosing your Waco over.

I know this thread has not seen much action for quite a while, I just wanted to throw a bone out to a great flying model. I picked one up at an estate sale a few months ago and finished it off with an electric conversion. Flies like a dream at 55 lbs and 11,000 watts.

How does one join the Waco Brotherhood? Just rolled the plans out on my Barth 1/3 scale. Thanks for any input.

Hi Guys,
I have been away for a while. I had made a career change and been very busy with my new job. I have also had some health issues and I am getting ready to have another back surgery. With that being said my modeling interest are moving in a different direction. I will be moving away from giant scale and going small electric. I have decided to sell my prized WACO. If there is anyone interested in the WACO and willing to pick up in the Cincinnati Ohio area send me a PM. The plane will be receiver ready. You can look back through this thread to see all the details on the plane. The engine has maybe 3 gallons of fuel ran through it. Just broken in good.
If I don't get any takers I will put it up for sale on consignment in the local hobby shop. This is a great opportunity to pick up a beautiful looking and flying WACO. This is a $6K build all day long. The kit is no longer available from AMR. I will accept $2K cash offer. A new 3W-157 engine sells for $1995.00 alone.

Update: The WACO has been sold, I hope the new owner will enjoy it as much as I have.

Later!!
Anthony

Sorry to hear that your selling your Waco, I know how much time and effort you put into it. Good luck with your new job Anthony and I hope your back issues will finally become resolved...
