I know T.O.M. thinks I'm crazy but if $ were that important to me I wouldn’t be in this business to begin with. I seriously do it because I love it, I love engines, I love planes and most of the people that share my affliction. Any design deficiency in any product that affects its use in any way is the responsibility of its manufacturer to correct, though I personally view the issue with DLE30 as minor idiosyncrasy as there are methods of dealing with it that essentially make it a non issue. Nevertheless, in an effort to give the people what they want, its correction does deserve consideration. With my always willing to help attitude and all to often foolish inability to say "no" I dove into it with the hope that a very minor modification that I could apply to any engine at will would have the desired effect, I'm sorry but that's not possible this time. What I have found that does provide relief is far too complex and time consuming for any one individual to provide, it also still leaves room for further improvement in other areas. Even if I were to disclose it here with pictures many trying to duplicate it would have mixed results, as I said it's complex. It would also relieve the manufacturer of responsibility of the issue to a large degree. The very best thing for everyone, including the manufacturer, is for them to develop the solution that could be applied easily in the field and apply that correction to subsequent production runs. Those that know me well would tell you that $ is not a very good motivational influence in my life which is why I gave my idea to the manufacturer no strings attached, even if they choose to utilize it, it would take some time. My primary focus and concern is always for the satisfaction of our customers and the prosperity of business in general including that of DLE.

Now you made us very curious Jody about that complex fix Is it the backplate, porting, ...?

FROM ANOTHER RORUM Re: DL-30 / DLE-30



The engine i did the jb weld fix can be put at idle way up in the sky then put in knife edge glide carb up carb down on the way to the ground. Level the wings and land while still idling. Pick the model up take it back to the pits idling,tip it twist it any wich way. Put it on the ground and give it a blat of throttle. It picks up better than it did before the modification. No hesitation at all.
The motor is now tollerant to poor tune also or at least a too rich tune.Hot starts are easier too. 91 octane 35 to1 revtex (Caltex) 28 deg BTDC timing after testing it at factory setting of 39 deg.
You could not even pick the model up prior or it would quit.

capt'n,

That Giles 202 is looking pretty good. The longer you wait to get it into the air the colder it's goiing to get . I've added baffles to the front of the cowl on my Taylorcraft to help move the hot air out a little more smoothly and keep the engine from over heating. It's ready to go up again this weekend if the weather holds up.

Interesting, new DLE 30 version:
http://www.rccanada.ca/rccforum/showthread.php?t=96271/

so it's a port timing/vacuum issue and a fix involves some welding and later a different cylinder design from the manufacturer.

Wrong modification for the dieing thing I believe

Welding?

That is for an idle quality issue that some have had, I've never seen one that needed it, has nothing to do with dying when tilted.

Maybe something like the JB welding? It may stay in place better?? I hope the new casting is not just a re-weld....but a entire new casting! Capt,n

The cowl is going to have lot of air exit room. The botton of it is pretty open and the side has a hole in it the size of a Webra 1.20!!!! I may get a new cowl if I like how it flys!!!!! Capt,n

CaptinJohn-
So exactly what is this DLE 30 JB Weld fix you mention from a different forum??
Do you have photos or can you give a better description?
Sounds like it fixes all the issues so I'm sure we are all curious??

FlymoreRC,
I had a simular problem on my gas engine (not a DLE 30) dying when I rolled to inverted. Discovered that the tygon pickup tube in my tank had become to stiff to allow th clunk to move to the top of the tank while inverted. Tygon tubing was only about 6 months old. I replaced the pick up tube with Hayes neoprene tubing and the problem is fixed.

Hey Tired Old Man I did buy my DLE-30 from Valley View and would have bought my plane there if I could have. I just wanted to get my engine a Yak 54 to mount it in and the only plane I could find at the time was Peak models. The plane was tied up with shipping problems. Now if you know of any problems with this plane I would like to know what they are. Cheers Don

I see the guy over in the other forum packed the intake manifold with Bondo and made a gradual blend from the insulator plate to the reed ports.

He said he used JBWeld <strike>but there must have been $45 worth of JBWeld in there if that's what he used</strike>
I stand corrected
He just used common sense porting practice. <strike>Probably took him a few days because he had to let the stuff cure out?</strike>

There's a couple pictures but if you have your engine manifold apart you can see what must be done.

Here you go guys.1/4 of each tube. 2hours work with heat

There he is again

So if we buy a new DLE 30, from now on a set of J-B Weld is included?

Not with engine....you will not need JB Weld right away...break the engine in first! Capt,n

For you guys that missed it, here is a link to a completly stock DLE30 that would quit in a split second when moved the wrong way. Easy cure so you can at least fly it and get it broke in more yet. That will help to. Again...I like my DLE30 and I am not any kind of dealer...just a person who likes engines! Capt,n http://www.rcuvideos.com/video/DLE30-Tilt-test-run

No, It's not backplate porting.

The problem, as Jody so well indicated in his post before yours, is that it requires thought, time, materials, and a little skilled effort to perform. Done wrong and an engine has the possibility of not running at all, or running well for a little bit then not running after an improperly installed correction detached from its installed position. Ideally, you would not want just anybody making the attempt to manufacture and install a home brewed fix since so many are a little bit hazy about mechanical endeavors. We now live and play in a buy and fly hobby atmosphere and so very many that are involved are very limited in mechanical ability, and/or patience. For them to make attempts and then fail would only perpetuate the original issue and likely generate new ones, ones where they would wrongly want to hold the manufacturer responsible.

Nice Terry

Terry, that is a nice part you made, maybe you will have a market to do a few other engines. A chance to make some side money!!!! Capt,n

Now ya did it Terry.

That IS the immediate solution ot the fuel puddling condition. More could be done in other areas to improve things further, but the re-worked intake plenum handles the primary concern. My concerns lie with the number of people that will try this on their own, manage to do something wrong, then take a grinder to their work to clean it out and start over. I can forsee the need to have a lot of aft case halves sitting on the distributor's spare parts shelves.

At least the only person they can be mad at is themselves
