Leroy, is this to look you are going for?



Or or is this the look ?



If if so are you just going to glue the pvc on to the covering then paint like one would do with vinyl rivets and hatches.

That's it Tony, the ones in your pictures have the covers on them, others will have the rings in the event you need to get in there, Back in the old days we put the rings on the dope finish by softening the paint with acetone and stuck the rings on and painted them with a brush.

Hi Leroy, I've been watching and enjoying your build for sometime now. I'm building a building a cub as well, to be finished as an L4 grasshopper, gotta finish this thing this winter!
Im also using a DLE 30, trying to find a muffler that will not make me carve a hole in the side of the engine cowl, gave you decided on a muffler yet that will provide a decent fit?
thanks

Todd hear are some pic's of a modified pitts style muffler the Bison from Canada made for me as we have a real strick sound rule at out field First one is the right side center is the modded parts the increased can size is the most important the holed baffle and the stacks help brake up the sound wave. this is on a RCGF-26 and note the extra mounting leg on the right side it is a must to keep the muffler from coming loose.
It met our sound requirement with 10 db's to spare.

I am sure they make a unit that will fit your 30 cc engine, this maybe the engine I will put in my cub.

Hope this helps

Cheers Bob T

Have you guys thought of using a can........for the sound thing. My DLE55r with stock muffler is under one of the more strick clubs I fly at' and I am under the clubs DB limit. My EME120 with cans should be even lower on the DB reader.

todd Tower Hobby has two mufflers for that engine, they are the wrap around Pitts type, Jtech is one and there is another but I would go with the jtech, you don't have to cut the cowl up using them, around $79.

J-Tech is a great muffler, Slimline may also carry a Pitts wrap around muffler as well. http://www.chiefaircraft.com/radio-c...flers/dle.html

I have two from Jtec. One is a wrap around pitts on a DLE 20 that is louder than all heck, and one, the same thing, on a super tigre 3250 that is the same exact muffler for the DLE 30 except it has a pressure nipple. That one was much less noisy. May be something to think about if noise is of concern. Just a thought.

The best muffler that I have found for the DLE 30 is from Mile High RC. It is very quiet when running a 19x8 prop. I have two of them. They pass the noise test with no concerns and they are inexpensive. I just comunicated with Mike from Mile High and although this DLE 30 pitts muffler is not listed on his site, he does have them. It is the same style as the "DLE 20 pitts muffler". Make sure you order the all tubular pitts DLE30 type not the one shown on his site for the DLE30/EME35

Guys I have Tried most all of the muffler brands in the past 5 years, 26 cc and up Pitts and side cans and until the last ones, none would meet the AMA 90 db at 9 suggestion J-tech make a great add on unit but you have to have the room, or build a spot for it. for those that are right on the border with the Db thingy you can stuff about 1/4 of a S/S pot scrubber in to the can section ( caution to much and you get to much back pressure) any thing to break up the sound wave,

Leroy Sorry to get so far off topic but the sound thingy at our field has been a real PITA at our field.

Cheers bob T


PS the one Bison made for me it was only about 15 $$more the a stock one

VincentJ

If purchasing a J-Tech muffler, you have the option to buy the larger style that comes with a larger can. It does help keep the noise down. If you purchase the "standard" style can it will be loud. I just purchased a wrap around Pitts for my DA-35 (with the larger can) and it is super quiet! The type of prop you run will also contribute to how loud it is as well...

Does fiberglass specialties make the super cub cowl for the 1/4 scale balsa USA? What else are the differences between the J3 and the super again? A longer fuse, more ribs...?

Randy

pilotbum

Are you going to make these inspection panels functional?

and what will you be using for the actual covers? Can't wait to see....

Pilotbum aka Randy

F/G/S make's a really nice super cub cowl, but I will do some reinforcing when I get to it just for the mounting points and any cut outs. Also the price was not bad in my book.

Cheers Bob T

Leroy Gardner

Yes on the cowl, it's in my post you put up. Body is wider as is the Balsa model, it has 16 ribs , Balsa's has 10 and its 1/2" longer, I added it to the nose. The J3 has different shaped rudder, stabilizer and elevator which can be redrawn for the super cub, not that hard to do. A lot of guys just put the super cowling on it and widen the nose, there are a lot of options you can do, it's builders choice.

Randy I'm building a scale plane and it will have all that the real one has. Rings have no function other then adding to the scale looks of the plane, same for everything else. Covers can be made from the bottom of pop cans for the dome effect which they have and some are kinda flat. Again I'm building scale so it will be as close to that as I can get.

Leroy

Leroy Gardner

Today I ordered the jTECH wrap around Pitts muffler for the DLE30 and it will likely get modified to one discharge tube to better fit the scale of my plane. I used a jTECH on my DLE20 and cut the can and one tube off and I didn't see or hear much difference. We are far enough from the whining public that noise is no problem.

Leroy

VincentJ

Leroy, why don't you ask them (J-tech) to modify that exhaust for you? They could easily change that to one pipe...

Leroy Gardner

I thought about that but it's just as easy to cut one off and plug it. I will have to see where the outboard tube is in relation to exit position on the plane, there isn't much distance to get a flex tube in there so I'm hoping the length and position of one tube will work out, should have the muffler by Monday at the latest.

I looked at the Bisson and the one at Mile High RC and they look like their made the same way as the crap mufflers that come with the engines. Jtech mufflers are made a lot better than most being tig welded and they don't need support straps.

J-Tech custom made one for my Cub, marvelous!!

Leroy Gardner

Some yrs. ago I bought a special made muffler for a 1/5 scale mustang with a DLE55 engine from Jtech, they were making to order at the time $110 shipped. It was real nice looking until I went to put it on and found a gob of weld and restriction at the out board screw hole so got the cutters out and cleaned it up. I e-mailed them and told them what I found and what I had to do in order to use it and mentioned it should have been done before they sent it to me. Their response was if you don't like it send it back, I let it go at that but I can't sat what I thought about them at the time.

They build a good muffler now and have even improved on them but I look else where when I buy one.

Getting back to the tail. I did put a make shift jack screw in just for the fun of it, it kinda looks like one too and is visible all closed up, "anything worth points" to the judges. Looking at the real tail I wondered how the covering transition was going to look and be accomplished when I do it, like how much of the lower fin is it stuck to to get that nice flair on the front base of it, it just looks odd. The fuselage tail post will be the last thing going on the plane after the finished parts go on, I need to slide the elevator assembly through a slot in order to get the hinges on and the tail wheel assembly is not going to look like that when I get finished with it, lots of small things to do to this one, it's all fun though. I can't believe all the work I got myself into when I decided to build a Super Cub and it's like that from one end to the other but fun stuff.

Leroy, it is really looking nice. You need to slow down though as you will be done in February and will have to just look at it until the thaw................
