Dang there TOM, you must have a serious burr under your saddle today. I can't see where Cherokee Flyer's comment detracted from or criticized Jody's excellent post in any way whatsoever. He simply added an additional comment or point of interest regarding Jody's post. Frankly sir, something you do all the time here in these forums. So I guess your post is criticizing yourself as much as anybody else on here.

Yes and no.

Jody gave a very nice, and brief, dissertation about how things work. There was and is a lot of room to delve even further into what happens with an incoming fuel mix, and the various components that effect the conditional effects before reaching the top of a cylinder. I didn't, and still don't, believe any more was needed to get the point across. More simply clutters up the intent of the original post and rasises more areas for discussion, which would not ultimately effect the end result, but would require a lot more time and effort attempting to illuminate those issues for people that would never understand. IOW, lots of additional work with no benefit. Just as is happening here and now.

TOM, this is a DLE30 thread right? You have a DLE30, so how are you coming on the mods you taked about doing to prevent the pooling of fuel? No need to go into deep...read a book thing. Just what works or helps and what does not work. Thanks Capt,n

So perhaps we agree, both your original post commenting about Cherokee Flyer's comments and my comments about your comments were unnecessary?! And of course, there were my comments about your comments ..... it goes on and on as you suggest. We've made our points.

So you are saying that Todd Syssa is lying?

PlaneKrazee,

The cylinder casting on my Syssa looks as good as any cylinder I've ever owned. Frankly, its external appearance is flawless. Can't imagine the DLE being any better.

From my Syssa ..... first day out and after the first flight, it was turning a Xoar 18-6 at 8600 with the HS needle set just to the rich side of peak. I think that falls within Todd's spec range and it can only improve from there. Have not tached it since. I've read here the DLE will outperform that.

My Feedback: (13)

I have heard that the DLE will outperform the Syssa also. That is why I wanted someone to post an engine RPM with the Vess 18 X 6 so we can see how much difference there is. I am thinking that it won't be as much as some people think.

Except for comparing performance on forums such as this, I really didn't care about tach readings on my Syssa. It more than meets my performance expectations in the air and thats what counts. It way out performs the Saito 180 it replaced, it runs smoother than the Saito, it sips fuel and starts effortlessly. I might add it runs in all positions too. No it isn't a perfect engine and few engines are. I'm hanging out here on the DLE thread because I think the future of these smaller engines is great and I have a project in mind where the DLE 30 would be a better physical fit than the Syssa. Hope to see the DLE issues resolved one day soon. DLE performance doesn't seem to be an issue, thats for sure.

Sorry for asking questions that are beneath the people that consider themselves in a class above the rest of us.

Ididn't miss it, I intentionally didn't mention it because the cooling is an effect of the expansion, in the DLE30,the expansion is the bad part.Prior to my post it appearedthat a few people wanted to better understand what goes on inside the 30, Ifeltit could be better understoodif it wereexplained in short and with arelatableanalogy. As I said, induction design is a science in itself and can get very complicated very fast, much more could have been written but I, and I'm sure everyone else, would prefer discussion on the topic to focus on how it relates to the DLE30 and in a form that most all can comprehend.

I didn't take your comment as finding deficiency in my commentary but it's exactly why I simplified it down to how it all relates specificallyto the DLE30. I'veseen many comments on what may cause or contribute tothe pooling but it's obvious that theywere not formed from study of the30 itself orin some cases a usable understanding of the properties of the components involved. That is why I used the analogy I did, something everyone haswith results anyone could reproduce. Further understanding requires handson investment andstudywith a disassembled engine.

It was intended as an addition, you said it very well.

Hey millertym2000 I have the Ultimate 120 from Nitro Models and have a CRRC Pro 26 in it. Over all wt is 10+ and it flys really well. In fact It is my favorite plane. The engine does hang out of the cowl and had to cut away for the muffler but it still looks pretty good. Nitro has this plane on for 199.00 bucks right now. I did have to hang the servoes a little different for the elevator. I do not like wire link to put elevator halves together. The plane is fast and more areobatic than I know how to do and land very stable no stall problems. Knife edge is easy and stright. Do not know what plane you are wanting to put the DLE-30 in. Oh and by the way the spects seem to be the same for the nitro and the cyclone 30cc ultimate even if it listed different. Mine is the yellow and white.

Jody,

Would the new plug design of the nkg cm-6 help with the DL 30 cc. ? It is a platinum plug design, I believe? Would it fire with a hotter spark and at least help with the issue?

Thanks in advance!

jedijody

My Feedback: (1)

I doubt it would make a difference, platinum is used on the firing end of a spark plug for a different reason. It makes the plug more resistant to fouling and gives it a longer service life, I don't think it would enable it to ignite large, heavy, globs of fuel, might be a lifetime spark plug though.

I have seen photos in the other thread that show some rough casting on the top fins.

As far as the Syssa muffler is concerned, the engine is close coupled, the single exhaust of the dle is located about as far back as the two Syssa stacks. A properly designed Pitts style muffler does not lower rpm, only db.

captinjohn

How about heat range of the spark plug. Maybe a tad hotter...but I am guessing there is not much to choose from in heat ranges with the plug style. Thanks Capt,n

So Jody,
Can we stuff the rear intake case on this thing to keep the velocity up, or will it cut down on the top end?

My Feedback: (1)

Yes, it has been done with good results but it's easier to just mount the engine with the plug at about 7:30 clock position. The stuffer in the pictures had no effect on the top end.

Nice looking stuffer prosthetic. You did a good job

captinjohn

I made a device that took some time to get done and on engine that has good promise. I ran my DLE 30 in 23 degree weather. It seems to really help. I am uploading it to photo bucket to view. I wl ilhave a link for that. The video will speak for itself. Thanks, Capt,n

Jody, Have you found anyone who can make these yet since DLEdoes not seem to want to do anything? Iwould like to purchase another engine but I will not, untill this issueis resolved. Weather its the stuffer or whatever.

DLE 30 in Nitro 120 bipe. 203km/h downwind out of a dive last Sunday.Well it certanly did not do it anywhere else in the flight. Garmin forerunner101 GPS on board

Nutzz

I will have 3 of those if the sort out my issues (which I belive they will), I just want to thank Jody for the information provided on this site as he has described and explained the problems I am seeing with 2 of my DLEs, to tell you the truth I think probably 90% of average pilots will not see the problems.

Keep up the good work Jody and as for the haters....................................
