RE: DL-50 engine
 

It's possible to convert the standard muffler to smoke. I've never done it though. Google is your friend.

My DL50 on an MTW RE2 pipe and Vess 23B consumes 1-1/3oz/minute for 3D flight.

RE: DL-50 engine
 

Smoke in a stock muffler..
Here's how I did it...

Find the nipple you would like to use...any old fuel nipple from an engine will do.
Figure out what size the threaded end is ..I used a drill guide to get a rough guess
Drill a hole in the muffler 1 size smaller than the size you determined in the previous step.... Room for error here
Ensure where you drill is going to be the hottest place in the muffler, usually in line with the exhaust opening so the oil will pass right thru the fire
Use a 10/32 tap to thread the hole in the muffler
Test fit fuel nipple
If its sung, not tight its good
Apply High Temp silicone gasket maker to threads of fuel nipple(found at Ace or automotive store, or wal mart maybe)
Screw snugly into muffler
Wait for silicone to dry
Install Tygon line to nipple
Start engine and smoke out your neighborhood!!!!!!!

Run time is hit or miss, you gotta play with your pump settings quite a bit but gassers smoke like crazy!!
Remember!!! Too much oil will cool it down so dont add more oil if you want more smoke...

Hope it helps!!

I have had a Skyshark Christen Eagle in the box for over two years now and have decided to put it together. Has anyone ran a dl50 in one of these planes? Thanks.

RE: DL-50 engine
 

Thanks a bunch for the info - that means my 16oz tank will give me about 12 minutes of flight, which is perfect, I'll set the timer for 9-10 minutes. I just may get a bigger tank too, they're only 7 bucks.

RE: DL-50 engine
 

Trust me, I will.

Thanks for the info! The same time I posted that question here I also emailed Bob from DL. Here's what he said...

So exactly where would you drill and tap or mount that fitting? I took a picture to ask this question..

To me Bob's explanation makes it seem like I should put that barb in the "pencil" location and run a brass tube over to the flame area.
But I don't know how I would get a nut on the other side of that barb in that location. I guess I've answered my own question here. I'll think I'll just use a nut and maybe even a 1/2" brass tube to get that oil to come out right in the flame.

Comments?

For you Amzoil lovers....I got a unopened bottle I will sell real cheap. I was to a very large Engine show that had a super large flea market. I came upon a amzoil dealer. He was desperate to sell the stuff. I looked at the different ratios ..ect, he had as I started to walk away he dropped the price way down. After reading about all the negitive things about Amzoil..I never used it and never will. Not going to argue whats best...but it is not Amzoil. Capt,n

RE: DL-50 engine
 

What are you, a Penzoil reseller?? [8D]
And it's Amsoil, not Amzoil btw.

RE: DL-50 engine
 

I agree the metal is way too thin, which is why I used the silicone gasket maker...I had JB Weld installed but since it is not actually a weld, it worked its way loose from the oil, fuel and vibrations..
As far as the brass tubing..I was thinking of trying the same thing but couldnt decide how to get it in the muffler and make it work so I just pointed the nozzle at the fire and I get puffy clouds.. I know if you can figger out a way to pre heat the oil it will be better but we are trying to make something do what it wasnt made to do ..right?
I would tap it right where you have it in the pic...right above the the exhaust and let it drip...even inverted it will work cuz the muffler will be hot enuf to "preheat" the oil and burn it off

RE: DL-50 engine
 

RCfan,

Can you tap into the edge of the flange? RC Showcase sells an injection orifice, cheap.

The jtec mufflers are thick enough to tap, carefully.

I have the christen Eagle by GP with the DL 50 in it and it is awesome plenty of power unlimited vertical,

Plane came in at 18.2 Lb and Im using a vess 22/b prop,

RE: DL-50 engine
 

I thought about tapping into the manifold (right by where it bolts on) but it didn't seem like there was quite enough width. I may do that though.

I don't think getting some brass tubing will be too hard. I ordered 3 different sizes of barbed fittings, sure one of them will be the right size to solder some gas tank brass tubing into it. We'll see. I'm about a week away from installing it all (waiting for the mailman), when I do I'll post a pic or two.

RE: DL-50 engine
 

Bosco,

I covet your Eagle. And I've also fallen in love with the DL 50 (have two nowone in a GP 27% Extra and my second in a GP 27% Edge). Back when, I did the "in-house" development on the Eagle and wrote the instructions for it, but they (we) discontinued that one and I never got one for my self. [&o] I've always loved the Eagle and I wish I could have flown one with a good (powerful) engine like the DL.

Take care of my "baby."

Tim

I have one NIB that I'm about to let go of. Too big for my pit crew (wife) to handle. I'm talking about the Great Planes 1/3rd scale version of the Christen Eagle. PM me if interested.

Mmmmmm lucky guy. Jump on that one if you can Tim.

RE: DL-50 engine
 

Hallo i am from greece and i am thinking of buying a DL 50 and i wanna know what i can do with the exhaust xan i find a better exhaust in order not to be as fragile as the stock?


Thank you..!

RE: DL-50 engine
 

There are many exhausts you can put on the DL. Any Exhausts made for a DA50 bolts right on. Many others like those made for the MT or G62, etc. will fit with very little work. It all depends if you want to stay with the stock style exhaust or if you want something different like a wrap around pitts style, canister, etc.

RE: DL-50 engine
 

Hi Guys!

Tomorrow I'll receive my DL-50 directly from China. I'll be putting it on a Yak-54 85in . As far as I read in the manual, the plane should come at about 16.8 pounds, but I don't trust this, so I suppose it will be somewhere near 18. Maybe I should open a building thread, so many of you could suggest me for some tips and tricks...

Best regards!

In reference to your comment about Amsoil, how in the world can you knock something that you have never tried and never will? I have used Amsoil Sabre for years and have never had a single problem. I guess you can have your OPINION and I can state my facts.

We need to get back on track. I have followed this forum for a long time. It has been shut down twice to my knowledge. When that happens, all the good and valuable information is not lost but after timeit gets hidden back amoung the dead forums. I got into gas about three years ago and the rc memembers were very helpful in overcomming theproblems I encountered along the way. Good luck to all and keep in mind we are here to share knowledge and solve issues.

RE: DL-50 engine
 

Hello everyone!!!

Maybe i can get help here. I have a DL50, it is a power monster, 22x8 prop turns 7600. Its still on mineral oil 1:30. It has about 2,5 liters of fuel burnt. I find one annoying thing. Midrange. The low midrange, lets say. It fourstrokes, splutters etc. I cant lean the LSN anymore because the idle becomes unstable and fast WOT causes choking. Is there any way to improve the low midrange in DL50?

RE: DL-50 engine
 

hi,

i received my dl 50 last week and fired it up for the break in yesterday. it is my first 50 cc. i dont have a lot of experience with gas (4 months gas and my gas engines have been a crrc 26, a cy clone of the zenoah 26 now the dl 50)

i do not know what ignition was with my crrc, the cy has an excell with ralph's rc xxx sticker (i think it is his. its a little sticker with rc xxx buried in foam on the plane so i cant see the exact number right now. i assume its his authorized ignition identity). the dl 50 came with an ignition in a bag with identical labeling to the excell that came with my cy.

all three of my gas engine planes use the 42 percent opti kill connected to a tx. my first two planes were used with a dx7 and my dl 50 plane i am using a RDS8000.
the crrc and cy ignition battery is a 2500mah 4.8 v. the dl ignition is a 2000 mah 4.8 v but from differant manufacture. a123 rc batt on all 3 planes.

now that i have given detail i have a question if you all do not mind.

when i charge my ignition on the dl plane, i hear a pop in the head. engine starts easy and engine seams to run fine (initial break in cycles per instructions)
i have never heard this pop with my crrc nor my cy. is this nothing to worry about with my mind paying more attention to situational variables with it being a new bigger engine with a new electronic package?
just want to make sure im not harming anything

edit. i just noticed that my reply was applied to the poster above me. this question is for anyone who would know

RE: DL-50 engine
 

Will the engine not idle at all. If this is the case you may have trash in the seat causing the needle to leak fuel and at idle and mid range a leaking needle seat will cause poor idle and mid range.

RE: DL-50 engine
 

What do you mean " when you charge the ignition"? Do you mean when you plug it in to charge the battery or when you turn on the ignition switch. Either way though you should not be hearing any noise from the head of the engine or anywhere else for that matter.

RE: DL-50 engine
 

That is STRANGE are you say the engine spark plug fires when you charge the battery.
