Simple, a better, more scale looking ARF came out. Also the cost of the hobby, some are getting out. (see the reasons listed)

The Pica kits build to a better looking, with as much scale detail as you wish to add, plane. Detail can be added to an ARF, but it is as much work if not more than building the kit or from the plans.

The only thing Cox had in common with the Pica kit was the name. Cox redesigned the Waco and did not leave much untouched.

The 20 looks like it has the power, but does it have enough thrust to over come the drag of this big biplane?

Power doesn't actually fly the thing, Thrust does. Pick an engine that will swing a large diameter, low pitch prop. That eliminates high revving motors, or at least those that need to rev to get their power. Biplane drag is speed dependant, provided you don't want to go fast, then the drag, and therefore thrust requirement, will remain lowish. Pick the lightest model you can find, then you don't have to go fast to fly, and you can use your excess power (thrust) to do the other stuff biplanes (Read Waco's) love to do, big lazy eights, slow stall turns, chandelles, and the rest. If you build heavy, then you bring both ends of the flight envelope closer together, and the whole thing becomes much less fun.

DLE 20 will be just fine. We have a guy at our field with a Great Planes Stearman with a DLE 20 and it flies great using a 17x6 prop. After watching it fly I have decided to go with the 20. I have a DLE 30 in my Aeroworks Cessna 195 and it is a rocket ship, way to fast even flying less than half throttle. It has a 90" wingspan. I would go with a rear carb setup.The DLE 30 on my Cessna has a side carb and does not run well at the lower power settings. Will be converting it to a rear carb soon. I guess that is one reason they have changed to the rear carb setup. Hopefully it will help it run smoother.

I'm all for the 20 but why do you think GP set the Waco up with the 30? It's nice to see mfg going the gas option.

Maybe back when this model was designed, the DLE 20 was not available. It was introduced after the 30. Most people want to over power their models anyway. I guess that is what the throttle is for. I believe if you want scale flying, the 20 is adequate. The manual even suggest a 120 four stroke (20cc) for this plane as an option.

You don't think anyone outside of the "Brotherhood" has templates for the Pica Waco? Just looking for clarification, not sure I understand the statement.

SkyPilot101

I do hope the 20 proves to be adaquate for spirited flight, I want a little more than to just lumber around. It would certainly make for a cleaner install!

I believe if you are at a low altitude enviroment you should have enough power for spirited flight.

That's about the size of it. They sure were not ever included by Pica, or Platt.

Well being that we are talking about engines and speed. I am going the dle 30 route and know that a 18x8 will be to fast but what about a 19x7 or 19x6. What pitch is going to be best.

Stickbuilder

Look at it like its the transmission in your car. Running an 18-6 is like leaving your car in second gear. It does not go real fast, but it will accelerate like a bandit. That's what you are after, the pulling power of a low pitch prop. Dan Hudson has an 18-5 for is Waco, and its just about perfect. That is a hard prop to find though.

Wow....Sounds like most are beating a Dead Horse...???

GP Waacooo doesn't have anything in common with the Pica/cox ,, well other than the name YMF Waco...

Possibly start a post that talks about all the diff. between each other ect ect...


Someone should post a build page. This would be helpfull and nice to see...

Skillet,

Last season I ran my dle 30 on a 20x6. Good thrust, moderate speed and the engine ran fine. It was installed on a Hangar 9 Taylorcraft. You might try that on your Waco.

I run a 19-6 on my DLE30 in a 1/4 CUB. Works great ... pulls extremely well without excess speed. Have wanted to try a 20-6 to see how that works also.

Wow!!!! I knew the DLE 20 would fit good in the Waco ..... I know this will have enough power to be "spirited" as someone has called it. I'm not worried after I have seen some 20's pulling 14# airplanes vertical for more than I will do with my Waco. I'll post more pic's soon.
Thanks,

kochj

The 20cc makes the engine cowl look larger than the os 1.20 4-stroke does. (the video hobbico posted, and in instructions)
Perhaps do to mounting the 4-stroke sideways and the 2-stroke inverted..??

Looks like a match made in Heaven!

There are several bulld pages in the Waco YMF thread. You are not going to be building anything with an ARF. (Sorry, I had to say that), but it was built by someone in China, or Vietnam). You are putting subassemblies together. To claim that you are building it is an insult to those who are cutting all their parts, and are actually building the model. I'm sure that you didn't mean it that way, but put yourself in the shoes of the guy who is doing it all.

You guys who chastise about builds or arf's .....I get what your saying about building, but think you are being a little critical An arf is like a partial build, So what!

In actuality you are assembling an ARF not building it. As they say whatever makes your tree bark, if it works for you then it is good. Not bashing, just stating the obvious.

Hey guys, how 'bout we get back to the WACO, and not argue over build vs. assemble... That's been done in other threads- but let's leave it OUT of this one!

Now WACO talk. I saw Minnflyer's WACO just after he pulled it from the box- what a beautiful plane!
