I did the maiden this morning... It went great. I love this airplane!!! The DLE 20 is awesome. It will fly the Waco scale at 1/3 throttle and at full throttle will climb almost vertical to where ever you want to go.... No need for any bigger engine on this 14 1/2 # plane... It balanced right on the 5 1/4 # back mark upper wing without fuel.. It lands awesome with wheel landings.

Glad to hear it went well. Finally finished the project I was working on and I'm starting this one. Prehinged surfaces are a welcome, as long as they did them right.

My hinged suffaces were good. I just never know how hard to pull on them to give them the "test"...... I made my pull-pull tail wheel set up and it works great... had to cut out a hole where the tail wheel is mounted and run plastic tubes for the cable to run through to the rudder servo, then balsa it back and cover it, but it was worth the hassle..

What engine are you going to use??

Thanks,

I'm still undecided on the engine. I have an OS 120 four stroke on the shelf but your report on the DLE 20 is making me reconsider using it.

I see the DLE 20 with muffler and ignition is a couple of oz lighter than the OS.

Hill202;

If you can do it, get you a DLE 20 and put it on your Waco. It is a perfect fit if you use a Hanger 9 alluminum mount. I ordered a special muffler from JTEC that cost $119. which was kinda pricey but it is a perfect fit for the Waco. They actually made them for the DLE 30 to fit on Aeroworks Cessna 195. I called him (JTECH) and he made some for the DLE 20. Gasoline is a lot cheaper than glow fuel too. I'm going to like the DLE 20/ Waco combo just fine.
A 120 4 stroke will fly it too though???

Yes the OS 120 (or anyone elses 120) will fly this model just fine. In fact, the OS 91 will fly it too. The original model was designed for a .60-.90 engine. I have flown one on a Supre Tiger .75 before. You don't have to overpower a model to fly in a scale like manner. The full scale airplane only used a 170 Horsepower engine.

Hi Bill,
You are right on. I've been saying without any proof that the DLE 20 would be a lot more than enough power to fly this 14 1/2 # plane. Today proved it!! I would not want a larger engine on it and the DLE 20 fits it perfectly if someone was wanting to go gas.....

How is the ticker doing?? I will turn 67 next Sunday and am hoping mine keeps working so I can keep R C ' ing. I flew with one of my friends this morning that is a true scratch builder that is 76 years young and you can not tell it by the way he acts and gets around. He can out do all of us and builds the most beautiful warbirds and etc. around OKC.
Also. how isyour new plane project going??

Thanks,

Thanks for the pics Cannonball. That wrap around muffler looks good. I guess that saved some cutting on the cowl right?

Bill,

I will defer to you on the power for the model but have to disagree on the full size power. From what I can find the original 1934-35 U/YMFs left the factory with either the Continental R-670 210 hp engine, 225hp W-670-K, 220hp W-670-6 (UMFs) or the Jacobs L-4 MB 225 hp engine (YMFs). The Waco Classic YMFs have Jacobs’s engines from 275 hp to 300 hp from the factory.

Hill202,

Not much cutting at all... I may have to make a couple more exit holes if the engine seems to heat up.... The cowl is open all around for air exit too.
Thanks,

I see you drilled access holes in the fairings for removing the gear also. I'll probably do that also before I glue them.

Does this mean I should go with a DLE 30

Yes, don't forget to make those access holes or you cannot get to the screws to take the gear off. I enlarged the center one also. I had to remove the gear because I forgot to epoxie on to the gear the center plate and it would not go in place without taking the gear loose and sliding it in under the farings. That is when I decided to do the access holes so I could get it off.......da.....
Thanks,

Hill202,

I know you are kidding but in truth the newer Waco Classics have gained weight since they were introduced in 1986 (gross weight from 2650 to 2950 lbs). If you go all out and add a lot of scale details and end up with a porker at around 18-22 lbs, yeah then maybe the DLE 30 might be needed..

You're right, I was kidding with you. If I go gas, it'll be the DLE 20. The manual shows a DLE 30 but looking at Cannonball's, I believe the 20 is a better fit.

The DLE 20 looks like the ticket for this plane! Nice install C.

I have no gas engines in my hangar & I'm thinking about the GP waco with the DLE 20. How about the vibrations of a gas engine long term? Servos? Structure?

Thanks!
V.

BTW C., where did you get the Hangar9 engine mount? (maybe the oredring no?), thanks

Gawd, I can't believe that I posted that about the 170 Horsepower. All along I was thinking 225 for the YMF. Old age and treachery is letting me down.

Well I used the 30 and have no regrets! That is why they gave us a left stick. I have really enjoyed mine and love the looks of it in the air! Mine came in at 14 and a half pounds and balanced perfect. The landings are a none event and other than the fact that it does not seem to like wind to much it has been a joy to fly. I am turning a 19x7 xoar at the moment but have a 20x6 waiting on the engine to finish breaking in.

And PS I have since added cockpit combing and a pilot to finish her off. I am also thinking of putting some combing around where I cut out for the engine.

Here's a vid of the 2nd flight of the day, 10th overall.

26cc Aerovate with Keleo Pitts
17x8 APC sport prop
4 aileron servos
2 elevator servos

"Pamela" from Slimline is the pilot.

After a few times fumbling with the wing nuts, I did the solder mod mentioned a few pages back. Huge difference!

My new favorite plane.

They really look good in action!

Looks good Skillet. You're gonna be trimming the grass with a 20 inch

Thanks Hill, I think it will be fine but I will be paying that close attention. It does not try to nose over any so we will see.

And I also meant to say that YES a 20 would fly it fine. The 30 is way more than is needed but a lot of fun! But on the advice from club members that have bi planes I went with the 30 because of the weight and drag that a bi has. Did not need to worry about that. This plane just floats!!

Hey, Guys here is my Waco that I just got done with last week.
It has a DLE-30 with stock mufler.
I used 2 A123 battery's and a Smart Fly Supper regulator.
Also a fiber optic ignition kill switch.
When done no balancing needed.
I flew it this weekend and love it. Even my 14 year old son fly's it.
The DLE-30 is hand full on take off.
It wants to turn left real hard so we just use 1/4 throttle.

I have nothing to say but good on building (assembling) this plane.
Great Planes Models are the best.

The 30 can be a lot of torque on takeoff so you have to feed in power slowly. Once it gets moving and the tail starts to come up it is great. I fly warbirds and all of those you have to do the same. Did you solder the nuts on. It makes assembly so much easier!
