Ihave a similar disclaimer at the end of all of my work e-mails:

This e-mail and any attachments may contain confidential and privileged information. If you are not the intended recipient, please notify the sender immediately by return e-mail, delete this e-mail and destroy any copies. Any dissemination or use of this information by any persons without the original author's express consent is strictly prohibited. Unless otherwise stated, opinions expressed in this e-mail are those of the author andmay not necessarily beendorsed by the author's employer.
<o></o>

Outlook automatically inserts it. In the world today, things like that are essential. Who knows what an e-mail or portions of it will be used for. Just standard stuff, nothing threatening at all.

As for the response from Hobbico, I know it is a little vague but they unfortunately have to be. If they give the green light to use a larger than recommended engine then someone somewhere would strap something crazy on it, injure himself then sue them because they told someone else a larger engine was OK. Lawyers are salivating looking for stuff like that. Talking to someone from GP off the record might be a different story but on the record, in an official company communication, they have to stick to recommending only what has been approved by their legal people.

Same goes for the tailwheel. I trust them when they say it is adequate and passed all of their testing. That does not mean it is the best of course. Sure, it could be done better. If their employee says, "Better install a Sulivan tailwheel" then they are again opened up to liability. Everybody will be demanding a new tailwheel to fix something that isn't necesarilyl broken. Some attorney somewhere will gladly file a class action suit for poor product design even if it really isn't. They just might win too just because the wrong wording was used in an e-mail. Companies have to be very careful about throwing around words like "inadequate", "defective" and so-on.

It's a funny thing. We sometimes want certain things in an ARF but then we complain about price. The manufacturer has to find a balance point where they can produce a nice product and still sell it at a price point that people will buy. Designing and building anything is full of compromises. They may have to find something like a tailwheel that is more than adequate but maybe not quite the best in order to meet the goals. If we want to upgrade then we are free to do so.

Once you've been grilled by an attorney a time or two you figure it out.

Rcflyerjoe,

Have you considered retrofitting your engine for a smaller sparkplug? It might minimize the appearance of the boot. Just a thought.

Ditto- It's called proprietary information, meant for your personal use only, no harm meant[8D] My company has it too, even goes as far as saying that if you get a virus from their email tough luck[sm=47_47.gif] I know what you mean though about going the extra mile on these expensive arfs, you think they could spring for a decent tailwheel[:@]

Mine came out at 14.6 pounds. Ya, a tad on the heavy side but will fly just fine at scale. Concerning that tailwheel issue, the Sullivan type seems to work fine on taxi trials. Pros and Cons please. MM

Thanks MM. About what I expected from the beginning. Most weights listed are on the low side. And when they said 12.75 to 13.75 I said over 14 then. So the 30 is where I am going as of now. I get home friday so I will get mine weighted up to see about where I stand, but I am going to have a heavier engine and another battery to account for.

Also MM did you have to add any weight to balance or were you able to just move things around.

Yes, I added weight to the front of the engine mount, about nine ounces and the battery is right behind the fuel tank. Hope this helps. MM

MormanMike; Whats under the covering in the tail wheel section? Is it solid? I'm getting ready to find out, but thought I'd ask you beforehand??
Thanks,

stick I guess I don't understand, but would you not want the same distance so they would move the same.

The geometry is just far enough out of kilter to make the top aileron move further than the bottom aileron, given the exact same placement. The Stagger is what causes this. The top wing is ahead of the bottom which gives you positive stagger. It messes with the throw enough to require a little offset in the connection. Here is a photo of Dan's Waco which shows the angle. Like I said, the upper goes at the trailing edge, and the lower goes 1/4 inch from the trailing edge. Trust me on this, or set them up equally, and then go back and do it like I said. You will see what I mean if you do it equally. Then you will have an extra hole in your aileron to explain to those who ask.

Bill, Waco Brother #1
To be able to use slave rods in this plane the ailerons will have to have the covering removed and install mounting points for the slave rod brackets to screw in too. Some work involved there. I might or might not....
Thanks,

Here is a 14# Stearman flying with a DLE 20.. Looks like plenty of power to me... he took off in a short distance and climbed to a good altitude fast and did a loop. Looks like it is going way faster than scale speed with the 20 to me. I'm glad to see this video because I already have my Dle 20 mounted and a special Jtek muffler thats made for the AeroWorks Cessna 195 to fit the Dle 30 to be retrofitted to fit my Dle 20. The pipes will exit straight down for a nice fit for my set up
Thanks,

Thanks for your input guys,

I will go ahead and do the tailwheel mod for my own peace of mind.

I think I will also go ahead with the 155. It is both lighter and less powerful by 1 hp than the DLE 30 which IS a recommended engine. I just thought it strange that the person who responded to me didn't seem to realize that fact. They specifically market it because it has "more power for the same size as a 120."

CannonBall, It's two pieces of 1/4 inch basswood glued together. One is about a half inch shorter and that piece fits into a recess under the tail you'll have to carve out to fit tight. It's all balsa under the tail so after it's epoxied, soak the surrounding balsa with thin CA. Then re-cover with Monokote. MM

If that 1.55 is anything like the .81 and 1.10 you should be very happy with it. Those alpha series 4-strokes are the best out there in my opinion.

You hit that head on. I have a 110A in a 10 and a half pound TF Mustang and that plane has all the power that I could have ever hoped for. The 155 will be great in this Waco.

I checked the Tower website last night and it said the Waco was backordered till May. I checked tonight and it was available with free shipping and a $15 discount. Ordered it right away. Its a good thing I get home from work before my wife does.

I am looking forward to joining in on all the discussion.

If anyone is building it with the DLE30 with the rear carb, doing the throttle is tough. I will post pics tomorrow on how I solved the problem

That's the only issue with a rear carb engine, the throttle can sometimes be a pain. I have two DLE-20's right now that I am trying to put in a 70" Revolver and a TF P-40. Almost have the Revolver done. My Waco got put on hold temporarily in favor of the P-40.

I'm using a DLE 30 with side carb. The instructions call for using 13 spacers and with the standoffs that came with the motor you need a 10-32 x 4" socket head bolts. I would like to know where to get this bolt. I have checked all the usual hardware retailers and no luck. I then did a Google search and came up with nothing. Have any of you guys gotten this far with a side carb engine?

"Test fit the engine with the spacers and standoffs using
four 10-32 x 4" [102mm] bolts and four #10 lock washers
(not supplied)."

I was looking for some 8:32 by 2 1/2 socket head bolts and had to go to a special hardware and bolt store in OKC. Look for something like that where your at. They are hard to find.
