Jody that stuffer looks really good. Do you know anyone that does injection moulding?

Can ypu please not use the word STUFFER with Jody`s name affixed as this was my contribution

The term "stuffer" has been around for ages when referring to filling and reducing volume inpoorly made induction tracts, you nor I are the first ones to use the term. I also collaborated with 3 other individuals and madethe first stuffers for the DLE30 nearly two months before your first post about one, Iwrote about it here and on another site, I didn't post pictures at the time because I was hoping the factory would do something with it, they asked me for what I had done and I gave it to them. You even PMed me and asked if I wanted you to remove your post about it because you knew I had already done it and was working with the factory on it. You cango aheadtake the credit for my work and informative posts if you wish.

Ido know someone in the injection molding biz, and I have investigatedthe process,there are several prohibitions in makingthe stufferfor the 30. The biggest is the cost of the tooling required for the mold, it's many thousands of dollars. There are not enough 30s out there to pay for it, not to mention I have a bit of a problem with profiting from the sale of it when it should be given to anyone that purchased a DLE30 and needsit. And contrary to popular belief, the factory has beenworking to solvethe problemsthat people have related to them, I correspond with them about itregularly. My luck would be that right after I paidthousands of dollars to manufacture a stuffer the factory would release one of their own or something that provides equivalent relief,then gives it away as they should.

The 30s that Ihave flyingdo not have any kind of stuffer in them, with the exception of the very firstone Iran and mounted allare just as they came out of the box and mounted with the plug at 6:00, none die in the air,when landing, or when turning rightbut all will die on the ground after idling for several secondsthen tilted carb up.

I won't make the stuffers for customers even if they want to pay for them, I just don't have the time to hand make them for everyone that may want them, that's why I posted the pictures. Iand others have been working on other things to help this engine that may be easier to produce or convince the factoryto change the design but all of it takes time.

I wish I could find an Ultra Stick Lite 120 like yours. They are out of production. I have a Syssa 30 coming.

OK guys I have read all of this thread and some others and I read a comment like that and it confuses me.(easy to do) I Have a GP Super Chipmunk that I know this engine would be great for, but I have held off buying because off the quiting issue. I do not want the plane for 3D just for aerobatic flight. How many guys have this engine and are enjoying it??

Geee... I built my first crankcase stuffer for a Mac 91 gokart in the late 60's. An thats just what we called it a crankcase stuffer.

Well I will go even further...Jody likes to take the credit for all he can. I was the first to post that mounting the DLE at a 20 degree angle would help this pooling problem a lot. Jody for a long time said people just did not know how to tune the engine and ..OH...the pooling problem when tilting engine has to be a pretty isolated thing! I even had video about a test...but could not upload it untill weeks later. Capt,n

Yes the "stuffer" was used to raise the crankcase compression to make help push the fuel/air mix through the trnasfer ports. It is completely different than a "Plenum runner" that is shown in a lot of the photos. It should be called that....a Pleum Runner! Capt,n

For the life of me, I cannot understand why DLE chose to side mount the carb and duct the fuel/air mixture around the case. Of the the 26cc engines that I have the biggest nit I have is that the carb usually has to stick out the side of the plane.

Any theories as to why the didn't put the carb on the back of the engine like the 50 and 55? No pooling problems with a shorter and more direct path. Not to mention the throttle linkages are more direct and easier to route. Most of these engines are mounted on 2 1/2" standoffs anyway.

3d I wondered that also and believe it could be because of the length that most planes have to use for the engine in a 30cc class. I know that you can cut the firewall so that the carb would work but not all planes are capable of having that done. I hate to cut a beautiful cowl also.

I guess DLE did make a DLE30cc protoype engine with rear induction. I understand it ran well. But the DLE people thought it would be too "long" of a engine with rear induction. I guess it may help to let them know our thoughts. So now is the time to post if you think the engine would be to "long". Also email the DLE company. They do respond. Best Regards Capt,n

Jody has done WAY more testing on these engines than anyone else on this thread that actually KNOWS what he's doing and people have the nerve to say that he's just wanting credit for it. That simply amazes me!!

I tend to agree with that !!! - plus all the work behind the scenes that doesn't get reported here [sm=thumbup.gif]

I don't understand what these negative remarks towards Jody are all about. He has done more for people on thee forums than any of these people could hope to do. Jody never claimed to take credit for anything that I seen. He has just been helping out. I had a quick look back and I can't see any posts where Jody claims anything to be just "his" idea.

edit: (sp)

Who cares who did what and when!! It seems to me people that post this kind of crap need to stay away.

Dang, Somebody that lives near this guy go give him a pat on the back he has solved it all! HA HA HA

Some of you guys just make me sit back a laugh. My 7 year old acts more mature than you guys!!

It looks like a lot of us put a lot of time into working the DLE30 to get the kinks out! You have to read the F.G. Forum too to find all the postings. That serial no thing...not a bad idea? Capt,n

<div>Can we drop the banter about this pooling problem?</div><div>
</div><div>Or at least everyone get over it til someone comes along with a cheap fix or the factory does?</div><div>
</div><div>Start a DLE 30 Pooling Problem thread and complain and whinge about it there if you feel you were ripped off.</div><div>Seems you either fix the intake plenum problem yourselves, mount the engine any way but vertical,  or sell the engine and get over it.</div><div>
</div><div>Piping up in here and b*tching how the factory is doing nothing isnt helping anyone. Nor is the arguments about who came up with the fix or what its called. </div><div>
</div><div>I want to see more pictures of peoples installs with the DLE-30 and prop data etc. </div><div>

Amen.

well said!!!!!!!!!!!!

I just found out santa is going to be leaving this engine under my tree! I came to this thread to do exacly what you said, learn about oils, octane, and props. This thread would be much more useful without the childish arguments.

So, I have run maxima 927 in my dirtbikes and atvs for a good while. It is one of the best (in my opinion) oils, however will it perform just as well in this engine? I also run cam 2 fuel, would there be a noticable power increase with useing that over pump gas?

There are a lot of good oils to choose from and different ways posted to break in. I have went to pennsoil for aircooled engines at 32-1 on breakin and because its good and easy to pickup. Then use echo 50-1 sys oil. I have not made the change to syn yet as I have only ran the engine on test stand. Xoar 18-8 was turning 8100+ . Idle was 1900 . This was after about three hrs of running at 3000 on the test stand. Now all I have to do is build the Yak 54 and go fly. OH I for got I use 91 pump gas.

All this moaning and groaning about the DLE 30 but nobody seems willing to step up and spend more than double the cost of a DLE 30 for a tried and true 3w-28i, which I know can run for over 600 hours and never give a moments trouble. Then you have the Zenoah G-26. Do people want a strong and reliable engine or a reason to complain? BTW, all three of the engines named in this post have their purpose, and none of them are bad engines.

Jody,

In the photos you posted, what type of material did you use to make it out of? I work with Marty as a mold maker. We were trying to figure out
what type of urethane to use that would cast into a silicone mold. I think most urethanes won't do well with gas & heat.

Mark

Hmm, never thought about showing to Marty, he's typically a one off guy rather than mass production. The pieces are made from body filler.

Do you even have a DLE-30?
